Corydoras is a genus of freshwater catfish in the family Callichthyidae and subfamily Corydoradinae.The species usually have more restricted areas of endemism than other callichthyids, but the area of distribution of the entire genus almost equals the area of distribution of the family, except for Panama where Corydoras is not present.

The pygmy corydoras lives in a tropical climate in water with a 6.0 - 8.0 pH, [9] a water hardness of 2 – 25 dGH, [9] and a temperature range of 22–26 °C (72–79 °F). [9] It feeds on worms, benthic crustaceans, insects, and plant matter.

It feeds on worms, benthic crustaceans, insects, and plant matter. It lays eggs in dense vegetation and adults do not guard the eggs. The female holds two to four eggs between her pelvic fins, where the male fertilizes them for about 30 seconds. Only then does the female swim to a suitable spot, where she attaches the very sticky eggs.
Corydoras paleatus is found in the Amazon basin, [1] and feeds on worms, crustaceans, insects, and plant matter. [1] C. paleatus has been known to produce sound; it does this by the abduction of its pectoral fins. This is used by males during courtship and intrapersonal communication, and by both sexes and juveniles when distressed.

The 18 specimens turned out to be a new species of long-snouted Corydoras: Corydoras caramater, researchers said. The new species was distinguished in part by its “mask-like blotch ...
Corydoras imitator is a foraging omnivore, and primarily feeds on zoobenthos, such as small worms, crustaceans, and insects; as well as freshwater detritus and plant matter. In the aquarium, it will readily accept most sinking dry foods, as well as live or frozen brine shrimp , bloodworms , and Tubifex worms.
