Pulcher Corydoras - Corydoras pulcher : Complete Fish Profile & Care Guide
Table of contents
Introduction
Pulcher Corydoras (Corydoras pulcher), distinctively larger than many of their Corydoras counterparts, boast striking aesthetics with intricate patterning. Their delightful personalities and serene disposition render them highly compatible with various community aquarium setups. To foster a vibrant and confident shoaling environment, it is recommended to maintain Pulcher Corydoras in groups comprising at least eight individuals, as they naturally exhibit shoaling behaviour.
Optimal tankmates for these Corydoras encompass small to medium Characins and Cyprinids, along with Gouramis, Dwarf Cichlids, and other congenial Catfish. However, it is advisable to avoid housing them with aggressive or significantly larger species. For successful breeding endeavours, a species-only aquarium is advised to protect their eggs from being consumed by other voracious fish.
Replicating the Pulcher Corydoras' natural habitat within the aquarium is key to their well-being. Utilizing a sandy substrate and introducing driftwood—preferably beech, dried and stripped of its bark—contribute to this emulation. Dim lighting enhances their comfort, while the addition of dried leaves, replaced every few weeks, imparts a natural ambience, avoiding water pollution. Supplementing the filter with aquarium-safe peat aids in simulating black water conditions.
Although aquatic plants are not found in the native waters of this species, Pulcher Corydoras still appreciate a well-planted aquarium. Given their sensitivity to deteriorating water conditions, consistent and meticulous maintenance practices are imperative. Regular significant water changes and meticulous substrate cleaning are essential to preserve their barbels and overall health.
Distinguished by silvery bodies adorned with prominent dark lines on either side of the lateral body plates, Pulcher Corydoras display several broken lines throughout their body and fins. Notably, their caudal and dorsal fins showcase transverse dark spots, while their first dorsal fin ray exhibits a sharp, large, and creamy-white appearance.

Sexual Dimorphism
Distinguishing between male and female Pulcher Corydoras can present certain difficulties. Nevertheless, sexually mature females typically exhibit slightly greater length compared to males and possess wider bodies, particularly when carrying eggs.

Natural Habitat
Pulcher Corydoras, a species exclusive to the Rio Purus region situated north of Lábrea in Brazil, South America, thrives in a diverse range of aquatic environments. These Corydoras are commonly found in small tributaries, areas of flooded forest, creeks, and sandbanks. Remarkably, their natural habitat is characterized by a scarcity of aquatic vegetation.
Breeding
Breeding Pulcher Corydoras can present some challenges, but the process is comparable to other Corydoras species. To initiate successful breeding, it is advisable to establish a separate breeding tank with either a bare bottom or a substrate of sand or fine gravel. Incorporating an air-powered sponge filter and clumps of java moss in the breeding setup is beneficial. Maintaining the breeding tank at an ideal temperature of around 75 degrees Fahrenheit and a pH of approximately 6.5 is essential. Utilizing RO water and filtering it through peat can also facilitate the breeding process.
Achieving the appropriate male-to-female ratio is crucial when breeding Corydoras, with a recommended ratio of two males for every female. Conditioning the group with a mixed diet of dried, live, and frozen foods is instrumental in stimulating spawning behaviour. Once the females are visibly full of eggs, significant water changes with cooler water and increased flow and oxygenation in the tank should be performed daily to prompt spawning.
During the spawning process, heightened activity may be observed as males pursue females. When the females are ready, they will permit the male to touch her with their barbels, leading to the classic T-position for egg deposition. The female will form a basket with her pelvic fins and lay 1 to 4 eggs. After fertilization, she will swim away to locate a suitable location, often on the tank's glass near fast-moving water, to deposit the eggs. This cycle repeats until all the eggs have been laid. Once spawning is complete, either the adults or the eggs should be removed promptly to prevent predation.
If you choose to move the eggs to a new tank, ensure it is well-oxygenated and possesses identical water parameters as the breeding tank. Adding a few drops of methylene blue to the water can help prevent fungus on the eggs. However, any eggs showing signs of fungus should be removed immediately to prevent its spread. The eggs typically hatch between 3 and 5 days later, and the fry initially feeds on their yolk sacs. Providing them with microworms and baby brine shrimp once they have consumed their yolk sacs is vital for their development. To promote the well-being of the fry, keeping them in a tank with a thin layer of sand rather than a bare bottom may offer better disease resistance.
Diet & Feeding
In the home aquarium, Pulcher Corydoras readily accept a diverse array of high-quality dried foods, such as granules, flakes, and sinking pellets. These contemporary food products are carefully formulated to cater to the fish's comprehensive nutritional requirements, ensuring their overall health and well-being. While these staple foods suffice for proper nourishment, the occasional incorporation of live, frozen, and freeze-dried meals, like mini bloodworm, daphnia, and tubifex, once or twice a week, can confer additional benefits to the fish's vitality.
As an omnivorous species in the wild, Pulcher Corydoras consume some vegetable matter. Although modern fish foods thoughtfully integrate such nutritional components, enriching their diet with blanched vegetables like spinach, broccoli, and zucchini can be a supplementary measure. To maintain optimal health, it is crucial to avoid overfeeding the fish, promptly removing any uneaten food the following day to preserve water quality and prevent potential health issues.
