Amblydoras nauticus

26. September 2014

Catfishes have no scales. But many species have bony plates that cover and protect the body. In the family Doradidae these plates are sometimes additionally armored by spines.

One of the most common species of Doradidae in Amazonia is the marbled talking catfish, Amblydoras nauticus. The species is not very popular by the natives, because the fish often do not swim away when a wading person comes along. Instead they erect the sharp, hard and serrated spine of the dorsal fin. In case one steps on that weapon: ouch!

Amblydoras nauticus are very nice, peaceful and undemanding catfish for aquaria which can be recommended even for beginners in the hobby.

Mormyrus rume

24. September 2014

We received a species of bred fish from Singapore which is usually only traded as wild collected ones: Mormyrus rume.

Currently the genus Mormyrus contains 24 species and subspecies. The determination is a very difficult task. Moreover, juveniles look totally different to adults. We obtained bred specimens of a species of Mormyrus from Singapore under the name of M. longiristris. A species M. longirostris does exist, but it originates from Mozambique and in that country work no ornamental fish collectors. It is much more likely the the fish belong to the species M. rume, which originates from Nigeria. We also get sometimes some wild collected M. rume from there.

However, both Mormyrus species are almost identical, not only externally, but also in respect of their aquarium maintance. The weakly electric fish are always involved in minor quarrels against conspecifics, what can be seen in harmless fin-damages. One should keep them solitary or in very large tanks in groups. Both species of Mormyrus can grow larger than 75 cm.

L107 / L184 Brillant-Ancistrus

24. September 2014

Among the most beautiful species of Ancistrus is this one. It originates from the middle Rio Negro area in Brazil and is not yet determined scientifically. Instead even two L-numbers have been given to it, namely L107 and L184.

The Brilliant Ancistrus is a very peaceful species. The number and size of the white spots differs in every individual specimen. There are fish with very small, numerous spots and others that have comparatively large, fewer spots. In some fish only the first third of the body has spots, but most of the specimens have spots all over the body.

We were able to import this beautiful fish from Brazil now.

For our customers the fish have code 26480-L 107-3 on our stocklist. Please note that we exclusively supply the wholesale trade. Available in limited numbers only!

Ophichthus apicalis

16. September 2014

Eels (in the scientific sense) are usually no ornamental fish. But there is a greater number of species than one expects, and many of them are used for human consumption. We were able now to import a species of eel from Vietnam that was to the best of our knowledge never imported before alive: Ophichthus apicalis. The species belongs to the snake-eel family (Ophichthidae) and has a gigantic natural distribution in the Indo-Pacific. Usually the up to 45 cm long species is found in the sea, but it is very often found also in brackish environments. The genus Ophichthus contains currently 75 accepted species.

We received specimens in two sizes, 30-35 cm long and a dozen fully grown specimens. Nobody would regard these fish as beautiful, but in any case they are very interesting!

Aphyocharax anisitsi wild

15. September 2014

There are species of ornamental fish that are kept and bred already for such a long time that their conspecifics living in the wild are almost unknown now. Such a species is Aphyocharax anisitsi, the Bloodfin tetra. The first importation was back in 1906. The fish proofed to be easy to breed and very productive. Nowadays Bloodfin tetras are represented in the pet shops all over the World almost exclusively by bred specimens, wild collected ones are hardly ever available.

So it is very interesting to see the wild specimens we were able to import now from Paraguay and to compare them with the bred ones. The most obvious difference is the varying coloration of the wild ones, whereas the bred ones look very uniform in this respect. The red coloration differs in the wild ones from almost absent to extremely intensive. On a photo the red colours look sometimes virtually artificial!

So aquarists who are interested in biological research have now the unique opportunity to study the sense of this different coloration. It is not very likely that the difference is a secondary sexual dichromatism (more red = males). Males of A. anisitsi can be recognized by fine hooks on the anal fin that appear as silvery refections on the photos. So one can clearly see that the most colorful is is a female in this case!

For our customers: the fish have code 206413 on our stocklist. Please note that we exclusively supply the wholesale trade.

Cynotilapia pulpican

15. September 2014

At the first glimpse Cynotilapia look very much alike the Malawi Zebras of the genus Maylandia In contrast to the zebras, in Cynotilapia the teeth are monoscupid (with two cusps in zebras). This difference is of more importance than one should think, for the zebras feed on Aufwuchs (eg the algae film on rocks etc. with all the containing microbiotics), whereas Cynotilapia feed on plankton (mainly small crustaceans), which is picked out of the water column. So the zebras and Cynotilapia differ very much in respect of their natural way of feeding.

On the other hand, Cynotilapia pulcipan can be kept in aquaria like any other Mbuna (Mbuna is the name for all the rock dwelling cichlids from Lake Malawi). It is best to keep them in larger groups of 10 or more specimens. It is of little meaning how this group is composed in respect of the sexes. People who want to breed will prefer one male for a greater number of females, but people who like simply to watch the fish do best to keep more males than females. In the latter case will always be one or two dominant males in the tank that display their breathtaking colours!

Cynotilapia pulpican become 6-8 cm long in the wild, but, like all Mbuna, they grow bigger in the aquarium. But even old males will not grow larger than 10 cm, females always stay smaller. So C. pulcipan is one of the smallest species of Mbuna known so far.

Synodontis robertsi

18. August 2014

The squeakers (Synodontis) are a very species-rich genus. More than 130 species are known, all of them originate from Africa. In the countries of their origin most species are used for food. In the aquarium hobby most species are unknown with a few exceptions.

Among the most pretty, smallest and rarest species of Synodontis is S. robertsi. Finally we were able to import a small number of that rarity once more. The species became known to science only in 1974. As far as it is known it lives exclusively in the river Lukenie, which is a tributary to the central Congo river. The maximum length reported for S. robertsi is about 10 cm. Against conspecifics and other fish this squeaker is completely peaceful. Squeakers are most active at dawn, but well settled specimens leave their hiding places also during daytime, especially when the fish are fed.

Squeakers are omnivorous fishes that feed readily on any type of usual fish food. These fish become usually very old in aquaria. They reach easily an age of 10 years or more.

Tetraodon miurus

18. August 2014

The Congo Puffer is one of the most remarkable species of freshwater pufferfish at all. The strictly solitary living species is a predator. It prefers to spend the day completely burrowed in sand. Only the mouth and the eyes peep out of the lair. If a potential prey comes along the puffer shoots out of the sand and bites the poor victim‘s belly off. Later the complete fish becomes eaten.

The ability to change the coloration is also remarkable. They can be brick red (as on the photos), but they can also be black, grey with black dots or marbled olive green. The puffer use this ability in case no sandy bottom is available. In this case the fish simply mimics a stone.

The maximum length of Tetraodon miurus is about 15 cm. It is necessary to keep this species in a single-species tank as a single individual. This tank, however, can be comparatively small, for the puffer does not swim a lot.

For our customers: the fish have code 191303 (6-8 cm) and 191305 (9-12 cm) on our stocklist. Please note that we exclusively supply the wholesale trade. Available in very limited numbers only!

Kryptopterus minor

15. August 2014

The “Ghost catfish” has been kept for more than 80 years under a wrong name in our tanks. Initially it was determined as Kryptopterus bicirrhis, afterwards as K. minor. However, both determinations proofed to be wrong, the species was in fact new to science and still undescribed! Now it has a final name, ie Kryptopterus vitreolus. Please see http://www.aquariumglaser.de/en/archiv.php?news_id=700 for more details of the case and pictures of K. vitreolus and the “real” K. bicirrhis.

Now we were curious how the “real” Kryptopterus minor looks like! So we ordered from one of our suppliers in Indonesia glass catfish from the Kapuas river on Borneo, where K. minor occurs. The species is in fact very similar to K. vitreolus. Especially in our fish, which have show size (up to 8 cm), the morphological differences between K. minor and K. vitreolus are hardly recognizable. But there are very obvious differences in coloration. K. minor has a bright golden-yellow back, a iridescent stripe over the anal fin and bright blue eyes.

Like Kryptopterus vitreolus K. minor lives in very soft, acidic water in the wild. However, adaptation on other water conditions is very good, as it is in cardinal tetras and other blackwater fishes. By far more important than imitating the chemical water conditions found in the wild is partial water change on a regular basis in the home aquarium. The fish simply need clean water with as few pollution and bacteria as possible.

Nematobrycon palmeri wild

12. August 2014

The
emperor tetra (Nematobrycon palmeri) belongs for decades already to the
most beloved species of tetra at all. This is due to its great beauty
and interesting behaviour. The species is available the whole year
through as bred ones.

Wild
collected ones, on the other hand, are available only seasonally. We
recently obtained once more a good shipment of these beautiful animals
from Colombia.

Wild collected and bred emperor tetras differ – as
it is the case in most species of tetra – mainly in respect to the
figure. Wild collected ones are much more gracile than bred ones for the
food in the wild is by far not that opulent as it is usually in
aquaria. In respect of coloration one can say that there is no
difference between wild and bred ones: both are very beautiful!

Neolebias trewavasae

12. August 2014

The genus Neolebias contains 12 species of small tetra from western Africa. Neolebias trewavasae attains a maximum length of about 5 cm and is one of the largest members of the genus. Sadly the species is only very rarely available in the trade, so we are glad that we could import them now once more from Cameroon.

The regular coloration of the pretty fish reminds one strongly in the coloration of the South American tetras of the genus Nematobrycon and Impaichthys, the emperor tetras. The quiet and grave swimming behaviour is also very similar in both groups. This is the reason why we suggest the common name “African Emperor tetra” for the species. But a real royal outfit get the fish in breeding condition. The males become deep red then. Sadly we have no picture of that coloration on our own, but in fishbase such a picture can be seen: http://www.fishbase.org/Photos/PicturesSummary.php?ID=11255&what=species

Trachelyopterus fisheri

5. August 2014

Currently we can offer a very odd species of catfish, namely Trachelyopterus fisheri. Initially this species of driftwood catfish orginates from Colombia where it is found in the system of the Rio Sucio. From that area only very occasionally importations appear. So we are quite happy that we have an adult wild collected male of this extraordinary species in stock.

Like their close relatives, the bottlenose catfish of the genus Ageneiosus, Trachelyopterus males develop a mighty dorsal spine, a penis-like organ (which is used to fertilize the female internally) and thick maxillary barbels during the mating season. All these feature vanish after the breeding season in Ageneiosus. Males and females cannot be told apart externally then. It is unknown wether this is the case in Trachelyopterus, too.

Interestingly this rare species is bred already commercially in Indonesia as an ornamental fish. We also have such bred specimens in stock. The coloration differs a lot individually. In our fishhouse the animals are swimming around the whole day through and obviously love to company of their own.

Trachylopterus fisheri becomes about 12-15 cm long It is a peaceful species, but very small tankmates may be taken for food.

For our customers: the large wild collected male has code 297546 on our stocklist, the bred specimens from Indonesia (which are 6-8 cm long) 297543. Please note that we exclusively supply the wholesale trade.

Toxotes blythii

31. July 2014

This
archer fish that lives exclusively in freshwater originates from Burma.
It has been discovered as early as 1860 and received its correct
scientific name in 1892. Since then it has not been found anymore. Only
in 2004 the first specimens appeared in the international trade and were
celebrated as a sensation. These first specimens were extremely
expensive, but nowadays the price is on a normal level and so any real
fish enthusiast is able to keep this beautiful fish at home. Currently
we received a shipment with really nice specimens of this extraordinary
archer fish.

The
animals of our current importation have a very uniform pattern; this is
quite different to the specimens observed in former importations. We
add a picture of a specimen imported in 2011 as an example. Possibly the
fish in our current import represent even a species new to science, for
there are a lot of hints that the real diversity and species-richness
in archerfish is not understood yet. Currently only 7 species are
recognized in the genus Toxotes.

Sternrachorhynchus from Peru

28. July 2014

This week we introduced to you already a species of knifefish from Peru: Brachyhypopomus brevirostris (see http://www.aquariumglaser.de/en/news.php#1122). The odd Sternarchorhynchus, which is theme of this newsletter, originates also from Peru, but belongs to a different family, eg the Apteronotidae.

The number of described species of Sternarchorhynchus has risen enormously in the past few years. Up to 1994 only 4 species where known, in 2006 the number of known species increased to 10 and now (2014) 32 species are accepted! This makes the genus Sternarchorhynchus the most species-rich genus of the Apteronotidae. The main differences between the species can be found in the shape of the snout. When the fish occurred here only a quite rough determination was possible. This is why they are listed under the name of S. mormyrus on our stocklist. The analysis of the photos, however, makes it much more likely that our fish belong to the species S. goeldii, which has been described only in 2010. S. mormyrus becomes about 50 cm long, S. goeldii about 30 cm. Currently our fish are 14-16 cm long.

However, more interesting than the question how the fish should be named is their behaviour. The animals are a bit quarrelsome against each other. But they do not hurt their counterpart, they swim with high speed and breathtaking elegance around each other. The better swimmer wins the combat. Also a very special role of the snout can be observed while he fish are fighting: they use it like the sword of a foil fencer. The pictures published here are the first existing ones to document this fascinating behaviour.

Feeding Sternarchorhynchus in aquaria is no problem, the fish take readily any type of live and frozen food.

For our customers: the fish have code 293974 on our stocklist. Please note that we exclusively supply the wholesale trade. Available in very limited numbers only!

Lexicon: Sternarchorhynchus means “snout with the anus at the breast”; this refers, of course, to the long snout and to the fact that in Sternarchorhynchus the anus is placed immediately behind the head. mormyrus: means “mormyrid”; the members of the African fish genus Mormyrus have a comparably long snout. goeldii: dedication name for Emilio (actually Emil) Goeldi (1859-1917) as a appreciation for his merits regarding the knowledge of the animals of Amazonia.

Stigmatogobius sadanundio

21. July 2014

Most species of goby are ground dwelling fishes. Only few species have a free swimming behaviour. The knight goby is one of these rare exceptions. We can offer this pretty goby from India on a regular basis. Knight gobies live in estuaries and can live both in pure fresh and in pure marine water. However, it is best to keep them in brackish water (5-10 grams salt per litre).

The eyes of the knight goby have a reflecting layer. This led to the popular name “sleeper gobies” for the realtionship of the knight goby. Not so long ago the sleeper gobies were even thought to represent a family on their own.

This week we obtained an import of extraordinary beautiful knight gobies from India. Obviously they have currently breeding season over there. The species spawns on stones, roots etc. Sadly the larvae are extremely tiny and need full strength sea water, so no successful breeding has been reported so far. But even without breeding: knight gobies are wonderful fish! The species becomes about 8-10 cm long.

Pseudotropheus crabro

21. July 2014

The colorful mouthbrooders from Lake Malawi – the so called mbuna – belong to the most popular aquarium fish over decades already. They are also called the “coralfish of freshwater”, for – like their salty relatives – they unite splendid colours and a rather quarrelsome temper. The latter is due to the very restricted food in the wild – both in the coral reef and in Lake Malawi. The sparse food is defended heavily, even when there is no need for this behaviour anymore in the aquarium.

The wasp mouthbrooder (Pseudotropheus crabro) has found a very special resource of food. It lives in caves and cleans the large bagrid catfish from parasites. These bagrids are called Kampango all over the lake, the scientific name is Bagrus meridionalis. The large predators recognize the cleaner fish even in the darkness of the cave due to their contrasting yellow-black coloration. Dominant males of P. crabro become very dark, almost black. This says other males to stay away from him and gives a hearty welcome to all females.

For our customers: the fish has code 568252 on our stocklist. Please note that we exclusively supply the wholesale trade.

The Dwarf corydoras (Corydoras pygmaeus) belongs without any doubts to the most attractive and interesting aquarium fish for small tanks. This dwarf becomes only 2-3 cm long and is a somewhat untypical member of its genus, for most species of Corydoras are bottom dwellers; C. pygmaeus prefers to swim in the open water column.

Kryptopterus geminus

30. June 2014

The glass catfishes of the genus Kryptopterus are close relatives of the Wels catfish (Silurus glanis). However, in contrast to this giant among the freshwater fishes (Wels catfish can attain a length of up to 2 meteres), the glass catfishes stay small. The largest species known so far (K. cheveyi from the Mekong basin) becomes about 35 cm long. However, this species has not been imported yet for home aquaria.

The biodiversity in Kryptopterus has been discovered only recently. Currently 19 species are recognized, 7 of them have been described after the turn of the millenium. Among these late discoveries is the most common glass catfish in the hobby, Kryptopterus vitreolus, which is “the” glass catfish in pet shops all over the world. This species becomes only 6-8 cm long and has been misidentified over 80 years as K. bicirrhis or K. minor. For more informations on that topic, please see http://www.aquariumglaser.de/en/archiv.php?news_id=700.

Kryptopterus geminus also belongs to the late discoveries and has been described as separate species only in 2003. Before that it was thought to represent a population of Kryptopterus cryptopterus. The latter is restricted to the Malay Peninsula and Indonesia, whereas K. geminus inhabits the large river basins of the mainland of Southeast Asia: Mekong, Mae Khlong, Bang Pakong and Chao Phraya. In contrast to K. vitreolus K. geminus is less deep in body and has a strong, blue-silver tinge on the sides. K. geminus attains a maximum length of about 15-20 cm and so it fits perfectly for larger aquaria.

For our customers: the fish have code 422104 on our stocklist. Please note that we exclusively supply the wholesale trade.

Lexicon: Kryptopterus: means “with hidden fin”, this refers to the very small dorsal fin. geminus: means “twin born”, this refers to the strong resemblance to K. cryptopterus.

Chaca bankanensis

26. June 2014

The frogmouth catfishes of the genus Chaca are very unusual fish. Only four species are known. The look quite similar to each other and form a catfish family on their own, the Chacidae.

Chaca lie on the bottom without any move for most of the day. They wait for shrimps or small fish that take them for stones and want to feed on Aufwuchs. As soon the potential prey sits down on a Chaca and wants to start to feed, a huge mouth opens and the shrimp or fish ends up as food itself. Some species of Chaca even have small lappets on the skin that imitate algae and makes their hunting strategy even more effective.

Chaca bankanensis is a blackwater species. Usually this species s reddish brown to brick red; it has only few skin lappets.

All species of Chaca become 15-20 cm long. During acclimatization the catfish often refuses food for quite a long time. So it is best to give number of live shrimps or feeder fish in the tank and to wait. Sooner or later the Chaca will start feeding.

Platystomatichthys sturio

16. June 2014

Finally we are able again to offer one of the most bizarre species of predatory catfish of Amazonia: Platystomatichthys sturio. Anyone who sees the fish for the first time will think that the animal is distorted; however, the upturned snout-tip is rather species-specific. Nevertheless the grade of this upturn differs individually and depends also a bit from the age of the animals. The maximum length of the species, which has a very wide distribution in Amazonia, is about 40 cm.

The sense or the reason of this upturned snout-tip are unknown. The species has extremely long barbels and prefers to swim against a strong current. Maybe the snout-tip helps to localize the prey or it may have a similar function as the spoiler of a car and helps so save energy while swimming against the current. There is also a lot of speculation that this upturned snout-tip is an artefact from keeping the fish in aquaria and resuls from swimming against the glasses of the tank; however, this sounds quite unlikely, for first of all allmost all – even very small – specimens can show this phenomenon and, twice, the species is not shy at all and tends not to panic and crash with anything.

Against conspecifics and other fish that are too large for prey, Platystomatichthys sturio are very peaceful.

For our customers: the animals have code 280705 on our stocklist. Please note that we exclusively supply the wholesale trade. Available in limited numbers only!

Lexicon: Platystomatichthys: means “fish that looks like a Platystoma”; Platystoma is another genus of fish. sturio: means “sturgeon”, which refers to the similar body shape.

Hydrolycus armatus

10. June 2014

The complete opposite to the Yellow Phantom Tetra is the Giant Waterwolve. This fish-eating predator attains a maximum length of 75 cm and is thus the largest species of the four members of the genus Hydrolycus. Of course this animal is much sought after by owners of really big tanks and public aquaria; sadly larger specimens are difficult to transport and this is the reason why the fish that is anything but rare in the wild is hardly ever imported.

We tried really long and now finally managed to import a larger number of juveniles from the Orinoco which are perfectly suited for the acclimatization in aquaria. Now enthusiasts have the unique chance even to keep a group of these fascinating predators. Against conspecifics and other species of fish that are too big to be seen as prey Hydrolycus are absolutely peaceful.

For our customers: the fish have code 259631 (4-6 cm) and 259632 (5-7 cm) on our stocklist. Please note that we exclusively supply the wholesale trade.

Amatitlania sp. Honduras Red Point

4. June 2014

The Convict cichlid (Amatitlania nigrofasciatum, formerly Cichlasoma, Archocentrus or Cryptoheros nigrofasciatus) was for a long time one of the most popular species of cichlid in the aquarium. Nowadays it becomes rather rarely seen. Instead of that species another Amatitlania appreared some years ago on stage, named Amatitlania sp. “Honduras Red Point”. These fish seem not to become much larger than 6-7 cm and are comparatively peaceful. The origin of Amatitlania sp. “Honduras Red Point” is much debated, but still no solid data are available.

Mesonauta festivus

3. June 2014

We received from Brazil very nice, wild collected flag cichlids. M. festivus is usually not kept due to its coloration, which is not very spectacular, but due to the interesting and peaceful behaviour.

But the animals that reached us now have a very interesting, blue pattern in the face. The scales also show an attractive blue shine. Moreover – this is of course not visible on the pictures – the fish are very curious and tame. Mesonauta usually are rather shy during the phase of acclimatization.

Trigonostigma heteromorpha

27. May 2014

Genetic investigations showed that there is not only one species of harlequin barb, but a number of sibling species, which have to be described scientifically yet. This becomes very obvious when we come across wild collected specimens. The depicted animal, for example, is a wildcaught from southern Thailand. It is much more elongate than the “normal” aquarium strain of T. heteromorpha.

Microctenopoma fasciolatum

27. May 2014

Our current import from the D.R. Congo contains inter alia two pretty species of dwarf bushfish: Microctenopoma ansorgii and M. fasciolatum. While M. ansorgii, the Orange bushfish, is imported on a rather regular basis, M. fasciolatum is found only very rarely in the trade.

The Striped bushfish – this is the common name of M. fasiolatum – can be compared best with the gouramis of the genera Colisa and Trichogaster in respect of care and behaviour. Like the gouramis, M. fasciolatum is a peaceful fish that feeds on small insects, crustaceans etc (in the aquarium it feeds on all types of dried, frozen and live food) and becomes only a bit quarrelsome during the breeding period when the bubble nest is built and becomes defended.

Males and females can be distinguished best by the coloration of the fins, which are spotted in males and plain in females. The coloration differs drastically depending on mood. For example, sometimes the fish show a cream white horizontal stripe which cannot be spotted at all in other mood-depending patterns.

The maximum length of this species is around 8-9 cm, the fish become sexually mature at about 5 cm total length.

For our customers: the fish have code 117002 on our stocklist. Please note that we exclusively supply the wholesale trade.

Lexicon: Microctenopoma: means “small Ctenopoma”; Ctenopoma is another genus of bushfish. fasciolatum: means “striped”.

Large wild collected Zebra Oscars arrived!

27. May 2014

The Oscar (Astronotus ocellatus) is by far the most popular species of large cichlid from South America. This is not only because it is so splendid coloured, but also due to its behaviour: the fish becomes much larger than 20 cm, but is of calm nature and can thus be kept and bred properly in medium sized tanks of 120-150 cm length. Most Oscars in the trade are bred ones from Southeastern Asia and represent colourful sports that do not exist in the wild. This is the reason why the diversity of wild Oscar species is still only poorly understood. Currently seven species are formally described scientifically, but only one of them is widely accepted as valid, namely Astronotus ocellatus. However, this does for sure not reflect the natural conditions.

Now we could import from Brazil some large, 18-22 cm long Zebra Oscars. They are remarkablely more slender than “regular” Oscars and have a unique pattern. First of all the typical, species-specific ocelli under the dorsal fin, which are always present in “real” Astronotus ocellatus, are missing. When we take a look in the scientific descriptions of other species of Astronotus, our new importations fit best to Astronotus zebra, which has been described by Pellegrin in 1908 from Santarém.

Barbus jae

6. May 2014

Barbus jae is one of the smallest species of barb from Africa. It has been described from the river Dja in Cameroon. Sadly nowadays imports from Cameroon are very rare, so one has to be really lucky to find this jewel in a local pet shop. B. jae becomes only 2-3 cm long. Breeding B. jae is not complicated, but not effective and so the species is not bred by professional breeders. One should keep this small fish that is found in forest-streams at temperatures of about 20-22°C. Other water parameters are of minor interest. The male of B. jae are polychromatic. This means that each male has an individual coloration.

Beautiful P14/Itaituba, bred specimens

24. March 2014

The taxonomy of the black river stingrays is very confusing. Three scientifically described species do exist:
Potamotrygon henlei (described from the Rio Tocantins), P. leopoldi (described from the Rio Xingu), and P. garrapa (described from the Rio Branco).

In P. henlei several varieties exist that possibly represent different, separate species. All specimens from the Rio Tocantins have large, white spots. Nevertheless the fish from the Rio Tocantins represent two different species that cannot be told apart externally, but only by studying the teeth. These are very different and the feeding habits of both species are very different, too. P. henlei from the Rio Tocantins can currently be imported legally from Brazil.

The very beautiful small spotted variety from the Rio Tapajós (the city of Itaituba is situated at the Tapajós) is prohibited for exportation currently. So these fish are available only via bred specimens. We are glad that we can offer three of them now.

Wether the Tapajós/Itaituba fish belong to the biological species P. henlei or not is under investigation. Hobbyists call them P14. This is a bad decision, for the “real” P14 is a variety of P. leopoldi from the Xingu, but we can do nothing against it.

We are happy that even so special fish as these large-growing black stingrays are (they become at least 30-40 cm broad and need a real lot of space) are bred by specialized breeders and so the wonderful animals stay available – at least in small numbers – for the hobby.

Drought in Singapore and Malaysia

Currently about 80% of the freshwater ornamental fish traded worldwide are bred specimens. A larger part of them is bred in Malaysia and Singapore. The drought there is extreme, February 2014 was the driest February in the region since 1869! This affects strongly the breeder´s facilities. One of our suppliers wrote:

“The weather issue has affected the fish production, the breeder is facing shortage of water supply as there is no rain, and it has certain impact on certain fish production, for your shipment we might face some supply issue like Fantail 5cm (which we always update every week), Silver Marble Molly, Red Platy, Blue Gourami, Lemon Tetra, Pristella Tetra, Panda Cory and Red High Fin Sucker , the supply is limited at this moment and the breeder not able to tell us how many pcs they can supply to us on every week it will have to wait until they do the harvesting. Weather issue also affect certain level on the fish quality, due to the production issue the breeder might not able to supply us the good size fish on some varieties.”

Lepidocephalichthys guntea – the ideal aquarium loach

12. March 2014

There is hardly a second species of loach that is as good suited for the home aquarium as Lepidocephalichthys guntea is. The species becomes usually 6-8 cm long, only in very rare occasions larger specimens up to 15 cm have been reported in literature. The animal has a huge distribution area over the north of India and the adjacent countries. Here it often has to live under conditions that can be survived only due to the ability to breath atmospheric air.

The fish are completely peaceful against conspecifics and all other species of fish. Plants are not affected, but should be well rooted, for the loaches dig a bit of course. The water temperature can lie between 16 and 30°C, this is the span that the fish have to face in nature, too. The water chemistry, eg hardness and pH are of almost no meaning. Any tap water the fits for human consumption is also suitable for keeping Lepidocephalichthys guntea.

The sexes can be distinguished best by view from top. Males look quite famished compared with the females and have comparatively larger pectoral fins. The coloration of Lepidocephalichthys guntea varies a lot and this fact led to numerous synonyms. The coloration is not sex-specific or population-specfic and also varies mood-dependent.

There are nor reports of a successful breeding known by us, but it should not very very difficult. It is recommended to try to initate a rainy season for breeding. This means to make large waterchanges with cool (18°C) and soft water after a period that simulates the dry season (no waterchange for some weeks at high temperatures).

All in all: what the Peppered Corydoras (Corydoras paleatus) is for community tanks with South American fish, can be Lepidocephalichthys guntea for community tanks with Asian fish: a very hardy, nice bottom dweller that feeds reliably on all left over food of its tankmates.

For our customers: the animals have code 424003 on our stocklist. Please note that we exclusively supply the wholesale trade.

Ompok cf. fumidus

12. March 2014

We don´t always get what we want. Initially we ordered the Malayan Giant Catfish Wallago leerii for one of our customers. But we received a species of Ompok from our Singapore supplier instead. However, this error is understandable. Even professional scientists have in the past confused both genera quite often and described a number of (now) Ompok-species as members of Wallago. Nevertheless the error of our supplier is an advantage for us, for Ompok are very interesting and hardly ever available catfish.

First a short note how to distinguish Wallago and Ompok: Wallago has always 5 rays in the dorsal fin, Ompok always 4. This can be easily seen on our photos.

Ompok belongs, like glass catfish (Kryptopterus), Giant Catfish (Wallago) and Wels catfish (Silurus) to the family Siluridae. Maximum length in most species of Ompok is around 15 cm, only O. bimaculatus from India is said to reach up to 45 cm.

The determination of the species is not easy in our fish, for we known nothing about the origin of our specimens. There are not less than 27 valid species of Ompok and most of them look extremely similar to each other. Nevertheless we think that our fish most likely belong to the species Ompok fumidus, which has a wide distribution over the Malaian Peninsula, Sumatra, Borneo, Riau Island and Thailand. O. fumidus becomes only about 15 cm long (the largest reported specimen had 145 mm without the tail fin). It is usually found in shallow brooks with peat water. In our fishhouse the fish proofed to be very peaceful, but, however, small fish will serve as food.

All in all Omopok cf. fumidus is a very interesting new importation. This “Wels catfish en miniature” enables even aquarists with comparatively small tanks to keep this type of catfish.

Xiphophorus hellerii Wien Lyra

12. March 2014

Even in wild living swordtails one can observe the tendency in females to mate only with the most impressive males. And so in swordtails the swordfin developed. This fin is obviously a pure luxury without any practical use, comparable best with the train in male peacocks. The only use of this is to impress the females.

Under human care even luxury genes can become established which are already inherent genetically in wild fish, but which cannot become established in the wild for several reasons. One of these genes is the lyra factor in swordtails. This gene leads to a prolongation of all fins (except the ventral fins) in both sexes – also in females! These females find lyra males very sexy, but their desire cannot be fulfilled by lyra males. For the copulation organ of male swordtails (the gonopodium) is also a modified fin (the anal fin) and thus much too long for use. You know the saying “have you ever tried to play mikado with cooked spaghetti”?

So one must use normal finned swordtail males for breeding. The offspring of the cross normal finned and lyra contains only in part lyra finned specimens. This makes breeding lyra finned swordtail quite elaborate.

We just received a shipment of wonderful, large lyra finned swordtails of the Vienna sport. Vienna swordtails are plain red albinos with red eyes. This sport is very rare and we can offer only a limited number of them.

Synodontis bastiani

7. March 2014

The squeakers (Synodontis) are a species-rich genus of catfish from Africa. Currently 131 accepted species are known. The maximum size of these fish lies between 8 cm and 60 cm. Most species attain a maximum length of 15-20 cm in the aquarium. In their home-countries these fish are very common and heavily used as food fish. Sadly only very few species are imported on a regular basis. Squeakers are very interesting fish, for they have a complicated social structure. One should always try to keep them in groups. Spacious tanks with lots of hiding places are essential for keeping these fish. Regarding water chemistry they are undemanding. They will live happily in any type of tap water. Food is mostly composed from meat, in the wild Synodontis feed in insects, small fish and Aufwuchs. If a Synodontis is caught and held out of the water is makes a loud squeaking sound – that is the reason for the common name of the genus.

We could import after a quite long time again Synodontis bastiani (S. eburneensis is a well-known synonym) from Nigeria. The species can be best recognized by the dark should spot. The body coloration can be plain or spotted, this differs individually. A special juvenile coloration has not been described for that specires so far. However, our smallest individuals have still two light bands on the caudal peduncle, which is a typical feature for many juvenile states of squeaker. According to the literature S. bastiani can attain a maximum length of 25-30 cm.

The blue shine all over the body is fascinating. Finally, the dynamic “Comet” pattern on the tail puts the finishing touches on the fish.

Rhinomugil corsula

18. February 2014

The Indian Four Eyed Fish belongs to the mullet family. It becomes usually 15-20 cm, in rare occasions up to 45 cm long. Like in the South American Four Eyes (Anableps) the eyes in Rhinomugil are parted horizontally. Nevertheless both genera are not related to each other. With the upper half of the eye the fish can see sharp above the water surface, with the lower part under water. Fascinating, isn´t it?

Gymnocorymbus cf. thayeri

18. February 2014

Sometimes we obtain animals as so-called accidental catches. And sometimes these fish have never been reported so far from the area we got them from. The silver widow tetra (Gymnocorymbus thayeri) is a close relative to one of the most popular tetras in the hobby, the black widow tetra (G. ternetzi). Both look quite similar to each other, but the silver widow has a golden or silver basic colour and an attractive, copper-red eye.
The silver widow is reported so far only from the upper Amazon in Bolivia and Colombia and in Brazil. We now received three specimens as by-catch to a new species of Serrapinnus from Peru (see http://www.aquariumglaser.de/en/serrapinnus-sp-aff-kriegi-peru_de_1578.html). To the best of our knowledge this is the first report of G. thayeri for Peru.
However, it is possible that our fish represent also a new species. Thus we decided to name them cf. thayeri (cf. stands for “confer”, a Latin word that means “compare with”).

Lexicon: Gymnocorymbus: means “with naked crest”; this refers to the scaleless region in the neck. thayeri: dedication name for N. Thayer, who sponsored an important ichtyological expedition through South America from 1865-1866.

Common name: Silver widow tetra

Pseudobagrus trilineatus

18. February 2014

This very interesting catfish originates from China. We received our first importation of the species now. The fish become about 7.5 cm long and live endemically (= they occur nowhere else) in the Dong Jiang influence in the Chinese province of Guangdong. There is no universal agreement among ichthyologist in which genus this fish should be placed. Most of them place trilineatus in Pseudobagrus, but some in Tachysurus.

Against each other our specimens are rather peaceful, but they look for some individual distance. So one should offer a hiding place for each individual on its own in the aquarium.

It is best to keep these fish at room temperature. The tank should be furnished with sand and stones, just as it looks like in a small river or larger brook. This environment suites the catfish best. P. trilineatus are carnivorous fishes; they take readily all types of flakes, frozen or live fishfood. One should not keep them along with too small other fish, for they could be taken for food also.

Betta splendens Mustard Gas

17. February 2014

There is no accounting for taste. But without any doubt the name “Mustard Gas”, which is one of the most disgusting chemical weapons, is a bad offense against good taste. The fish nevertheless are extremely beautiful. It is said that initially an US breeder named Jude Als has bred the first Mustard Gas Bettas. However, these pure breeding animals have looked very different. They had a blue or green body and yellow fins.

Nowadays bettas with the label “Mustard Gas” are bred mainly in SE-Asia. These fish are black (=melanotic) with orange or yellow fins. The fins have a black seam. In breeders language they are melanotic butterfly bettas.

Breeding melanotic bettas is difficult enough, for the females are usually infertile. So the breeder has to breed with females of other than black colours. The gene that is responsible for melanotic body coloration is hidden (recessive), so the offspring of the first cross looks completely like the mother. One has to cross back the daughters on the father or the siblings to get black, melanotic animals. Breeding melanotic butterfly bettas is even more complicated. This is the reason why Mustard Gas bettas are comparably rare and more expensive than other bettas.

Hemiodontichthys acipenserinus

17. February 2014

These strange whiptail catfish, in nature living in a sandy habitat, are regularly imported, although in low numbers. This species requires a sandy substrate, in which they can hide themselves. Because this is a shy fish absolute care needs be taken in the choice of tank mates. The reproduction of this species is not very difficult, if we consider its requirements. The male fish carries the eggs as a clutch, carefully surrounded by its enlarged lips for approximately 14 days. As soon as the fry is hatched, they are released and further care by the male has not been seen. Catching this fish should be taken with care because of the Odontods (little bony hairs on the exoskeleton) on the Rostrum. These can be entangled in the fishnet and could damage the fish beyond repair. Concerning feeding this species is not very picky and it will accept all available fish food, like frozen, flake or pellets. Especially freshly hatched brine shrimps are taken eagerly.

Serrapinnus sp. aff. kriegi

3. February 2014

The tetras which were called “Cheirodon” for decades are splitted now in several genera: Nanocheirodon, Compsura, Odontostilbe, Serrapinnus, and Cheirodon. They all have a generalized pattern with a black caudal spot and light spots above and below it.

We currently received a pretty species of that group from Peru. Sadly we were not able to determine it yet. Initially we thought they might belong to the species Cheirodon luelingi, but this could not be verified. Obviously our fish represents a (at least for Peru) new species of the genus Serrapinnus (this genus is defined by a strange, saw-like structure right before the ventral border of the caudal fin, which is formed from the so-called interhaemalia), which is very close to the well known S. kriegi from Paraguay.

So we call our fish now Serrapinnus sp. aff. kriegi “Peru”. Our largest specimens are about 4 cm long and obviously sexually mature. The animals are absolutely peaceful, very lively and healthy.

Eirmotus octozona

30. January 2014

This tiny barb is very enigmatic. It has been described in 1959 on the basis of specimens from the aquarium fish trade which were said to originate from Thailand (Bung Borapet). However, there have been no reports since then about any occurence of Eirmotus in Thailand. Oramental fish collectors formerly collected this species in the peat swamp forest of Ayer Hitam in Johor, Malaysia. This forest has been almost destroyed for oil palm plantations and all fish that lived there seem to be extinct now. In 2008 three very similiar, new species of Eirmotus have been described from Sumatra and Borneo. Our fish seem to belong to the “real” E. octozona.

Eiromotus are very delicate barbs, which become only 3-4 cm long and are perfect tankmates for small blackwater tanks. Nothing has been reported so far about the breeding biology of this unusual, very peaceful barb.

Pterophyllum leopoldi

28. January 2014

This is the third commonly accepted species of angelfish. The two other species are Pterophyllum altum and P. scalare. However, traditionally P. leopoldi is named “Dumerili” in hobby and trade, but P. dumerili is a synonym of P. scalare.

P. leopoldi originates from Brazil. Here it lives syntopically with P. scalare. P. leopoldi always swims with a characteristic “head-up” position, which reminds one very much of the flag cichlids of the genus Mesonauta. In fact, the genera Mesonauta and Pterophyllum are close realtives to each other. This typical swimming position even led to an anatomical detail: the lower filament of the caudal fin is always longer than the upper filament in P. leopoldi. This feature can be even used for determination!

We are able to offer once more wild collected specimens of P. leopoldi. The species attains a maximum length of about 15 cm. Regarding the keeping conditions: there are no major differences compared to that of the common angelfish, P. scalare.

Synodontis pardalis

We received with the current Cameroon importation this beautiful squeaker, which can attain a maximum length of about 20 cm. The species is known only from the river Dja and its affluent Libi. This is the reason why the fish is considered an endangered species, for the Dja is heavily destroyed and polluted due to intensive Cobalt mining. So it is very gratifying that S. pardalis becomes imported every now and then, which makes specimens available for breeding and conservation programs.

Synodontis pardalis belongs to a group of very slender species of Synodontis, as do also S. decorus and S. brichardi. Against each other they are astonishingly peaceful. This squeaker should be kept in groups of 5-8 specimens. Regarding feeding and water chemistry the species is undemanding.

Biotodoma cupido Peru

20. January 2014

The small cichlid Biotodoma cupido – the species can attain a maximum length of about 12-15 cm, but is sexually mature already at 6-8 cm total length – is probably the species of cichlid with the widest distribution in Amazonia. However, experts are merrily discordant wether all the different looking populations represent only varieties of the same species or represent different species on their own.

May that be as it is: the specimens originating from the vicinity of Iquitos in Peru can be easily recognized by the large, bronce- or copper-colored spot that is exhibited by the male and that makes the fish very attractive. Females lack this spot and have also a differently-shaped dorsal spot.

The fish are very peaceful – except when they start breeding. Then the openbrooding species becomes very aggressive against tankmates. These fish prefer floating water in the wild. Otherwise they are very adaptive and can be found even in tidal zones.

Once more we received a small jewel from the Congo basin. Again, a somewhat larger number of the Butterfly Barb Barbus hulstaerti could be imported, which was lost in the hobby for a long time. The colour variety with the large spot on the side is called “Lompole” after the collection site.

The lively fish reaches 3-4 cm in length and fascinates by its wonderful colours. Males and females can be distinguished by the diffrent coloration of the dorsal fin.

In their area of origin they live in flat, shady and comparatively cool jungle waters. The discovery site data indicate with water values of pH around 6; and a total hardness under 5° DGH no excessive problems for their maintenance.

Due to the complicated political situation in the Congo the availability of wild collected specimens is not secured, therefore ambitious breeders should take care of this swimming gem to secure their existence in our aquaria.

Pseudolaguvia muricata

11. December 2013

Catfishes from Asia are sadly not “en vogue” currently. On the other hand, many new, attractive species have been discovered recently, which are perfect aquarium inhabitants.

The first species of the genus Pseudolaguvia was discovered back in 1927, but only recently it was found that this genus represents a species-rich one. Pseudolaguvia are dwarf catfish that reach a maximum length of only 2-3 cm. 13 species of the 17 species known to date have been described from the year 2003 on.

A typical feature of the genus Pseudolaguvia is the adhesive apparatus on the belly which looks a broad fold. All species live in brooks or small rivers over sandy bottom. Usually the fish are found among dead plant material (detritus).

For the first time we could import now Pseudolagivia muricata. The charming animals become only 2.5-3 cm long and are no great swimmers. So they fit perfectly for small tanks. A tank for Pseudolaguvia should have fine sand on the bottom. One should also give some dead leaves in the tank. The catfish feed on almost any type of usual fish food – it has to fit the mouth, of course. Pseudolaguvia are absolutely peaceful against any tankmate, may it belong to the own or to different species. Plants are left unharmed also.

There are rather dark colored, elongate specimens and plumper ones with a lighter coloration. In all probability this represents sexual differences. Nothing is known so far regarding reproduction, but it is very likely that the eggs are deposited among plant material etc. and are left unguarded. These fish are kept best at room temperature. In the natural habitat the water is soft and neutral.

For our customers: the fish have code 445425 on our stocklist. Please note that we exclusively supply the wholesale trade.

Channa andrao

11. December 2013

One of the smallest and most colorful species of snakehead has been described recently. Since about 12 years this fish is in the trade under the name of Channa sp. “Blue bleheri”. This mouthbrooding species becomes sexually mature at a length of about 8 cm. In the wild, they hardly ever become larger than 10 cm. Under aquarium conditions they may become exceptionally about 15 cm long.

This species is known so far only from a swamp area in the north of India (West-Bengal / Assam). It can be easily distinguished from most species of snakehead by the lack of ventral fins. The most similar species is Channa bleheri. However, C. bleheri has always large orange-red spots in the caudal fin, which are always missing in the caudal fin of C. andrao.

Females stay smaller and have more red coloration on the body. Thus Channa andrao is one of the few species of snakehead in which the sexes can be easily distinguished.

Goldfish Oranda Tricolor

11. December 2013

In the minds of many keepers the goldfish is a coldwater fish and has its high season in spring time, when the garden pond season starts. This is of course true, but reflects only a part of the reality. The highly developed sports – like the orandas – often are better kept in aquaria than in outdoor ponds. The optimal water temperature for these fish is between 14 and 28°C.

Currently we received very nice three-colored Oranda Tricolor that were bred in Singapore. These animals are colored individually very different and in all probability they will also change some of their colours during their individual lifetime, which can be as long as 30 years.

The ideal home for such fish is a large tank with soft sand and only a mild current. Goldfish are social animals and absolutely peaceful against all tankmates. One must only take care that no other fish takes the long fins of the orandas as toys and thus jars on the nerves of the poor goldfish permanently. By the way: all goldfish – and so also all orandas – are a perfect weapon against duckweed. No plague of duckweed will ever appear in a goldfish tank, for duckweed is one of the favourite dishes of goldfish.

Atractosteus tristoechus

2. December 2013

The Alligator gars are so-called living fossils. They developed about 100 million years ago in the upper Cretaceous and haven´t changed much since then. Currently two genera live in the New World, namely Atractosteus (containing three species) and Lepisosteus (four species).

The members of Atractosteus can reach about 2 m in length (formerly they are said to have reached even 3 m, but formerly everything was better ;-)) and are thus the largest recent members of the Alligator gars. The three species are very similar to each other and differ only in details which are not observable from outside. Our specimens are currently about 5 cm long and have been bred in Indonesia. We believe the breeders regarding the identity of the species as we have no opportunity to verify or falsify this.

Among the ancient features of the fish are the very strange bony scalation and the remains of a “tail” in the upper half of the caudal fin, which is clearly visible in our baby fish. Gars do not breath only via gills, but also via the swim bladder which serves as a lung. So they can survive even in very oxygen-poor water.

Gars feed exclusively on fish, but can be easily accustomed to feeding by forceps. Against conspecifics and other species of fish the gars are absolutely peaceful as long as they do not serve as food. Alligator gars are gorgeous animals for large show aquaria.

so interesting from a biological point of view that every aquarist should know them.

Currently four species of sabertooth-tetras are distinguished. All have in common extremely large, saber-shaped teeth in the lower jaw that are used to spear other fish. In the upper jaw are holes in the bone that have the function of sheaths for the saberteeth when the mouth is closed.

Most often the orange-finned Hydrolycus tatauaia is imported, a species that attains a maximum length of about 40 cm. This fish occurs in Brazil, Colombia, Guyana, Peru, and Venezuela. H. armatus occurs in the very same range. It differs from H. tatauaia by the grey to black fins, a different-shaped spot behind the opercle, a less curved belly and (this is most easily recognizable) a species-specific colored adipose fin.

Dwarf livebearers

Finally we are able to offer once more both species of dwarf livebearers. Both are German bred ones. Dwarf livebearers are the smallest species of livebearing fish that are commonly kept in aquaria. Males become only 2 cm, females 3 cm long.

Heterandria formosa, also known as the “Least killifish” is the more common species. It originates from Florida and neighbouring states of the USA. It can be kept best at room temperature and does not need an additional heater, whereas N. elegans, also known as the “Teddy livebearer” originates from Colombia and needs rather high temperatures, eg 24-28°C.

Despite this the two species do not differ in respect to their demands. Even beginners can fulfill them easily. The water conditions (hardness, pH etc.) are of no interest and the fish feed readily on any type of fishfood that is small enough for the tiny mouths. Both species are absolutely peaceful.

The females of dwarf livebearers give birth to young fish during a period of several days. Each day only one or two babies are born. So one should keep them in small seperate aquaria with dense plantation over that period. The babies should be removed every day.

For our customers: the H. formose have code 421482, N. elegans 438352 on our stocklist. Please note that we exclusively supply the wholesale trade.

Platythelphusa armata

20. November 2013

Lake Tanganyika in Africa is a kind of very large aquarium. Hundreds of endemic species – endemic means that they occur only there and nowhere else in the world – live in Lake Tanganyka.

This week we have some specialities from the lake for you. First: Platythelphusa armata. This is one of nine species of freshwater crabs from Lake Tanganyika. Males and females look very different. Like all larger species of freshwater crab they should be kept solitary and in single species tanks. Only for breeding attempt the sexes should be kept together. Crabs like these are omnivorous and feed readily on any type of fish food.
