Breeding: This catfish is not especially difficult to breed. A 30 gallon tank. No special water requirements, will spawn in any water. Fry seem to have problems breaking through the thick eggshell in higher pH, so it may be better to breed them at lower pH. Spawning is slightly different from other corydoras, after the T-position is broken off, the eggs are produced. Eggs are layed in large clumps. Eggs and fry are no larger than other corydoras. Hierronimus describes that these fish breed in pairs, not in schools. Other C. barbatus are chased away!
Sexual dimorphism: Males are larger and more colorfull than the females. Fins are longer in the males. The females are larger and plumper behind their pectoral fins, and less colorful.
