This fish species reaches about 2.3 in.. The male is smaller than the female and in proportion to body length, the dorsal fin and pectoral fins are longer on the male than the female.
Corydoras paleatus is found in ponds, and feeds on worms, crustaceans, insects, and plant matter. Paleatus has been known to produce sound; it does this by abduction of its pectoral fins. This is used by males during courtship and intrapersonal communication, and by both sexes and juveniles when distressed. In reproduction, males do not behave aggressively toward each other, nor do they monopolize mating areas or females. The T-position is involved in courtship, as with many other Corydoras species.
It is a very good choice for the community aquarium, as it is a hardy, good looking, and peaceful fish. They can be successfully kept with other small, peaceful aquarium fish like live bearers, danios and tetras. It is sometimes seen in the shops as an albino form, although this is similar to other albino corys. It grows to around 7.5cm, and is easily bred at home.
These fish have sensitive barbels and one should have the proper substrate for them. To keep their barbels (whiskers) in the best condition one requires the fine gravel that looks like coarse salt. This is available in white and brown, both look good. Beware that fry are difficult to spot on the brown gravel. Gravel with sharp edges will cut their barbels (until they are gone). Their barbels are important for finding food, and thus remaining healthy.
These fish prefer a planted tank and like to nibble on the algae that grows on floating plants. The lighting must not be too bright and you need to set up hiding places for them as they like to hide from the light during certain parts of the day.
