Info
Ostorhinchus margaritophorus, Bleeker, 1855
Susceptibility to disease: very sensitive to transportation and somewhat tricky to acclimatize to, but then persistent with good feeding.
Social behavior: it is a schooling fish that stays close together, especially when in danger.
Peaceful towards other fish.
Tank: needs a well-structured tank with hiding places, well suited for coral reef aquariums.
General information: A very beautiful schooling fish that only takes on its full color in the tank.
Also shoals during the day, interesting breeding behavior as it is a mouthbrooder.
Breeding information:
The males carry the eggs in a throat pouch. Unlike Pterapogon kauderni, no finished fry are released but small pelagic fish larvae.
Spawning interval** 13 days
The larvae size* is 2 - 3 mm
The larvae can be caught with a light larval trap.
Courtship behavior:
The female swims trembling at the male.
* The water temperature influences the number of fertilized eggs and the spawning period (with a difference of e.g. 1° C, the difference can be ± 2-3 days) and, in the case of gonochoristic (separate-sex) fish or shrimp, the sex. If the temperature is below the usual regional temperature, mainly female larvae will hatch from the clutch, above this temperature mainly male larvae will hatch. Furthermore, the aquarium conditions (e.g. light duration, density) can also influence the sex.
** The spawning size or the number of larvae depends on several factors - age and condition of the parent animals, water conditions, food quality, stress factors and the dissolved oxygen content.
