The Dwarf Corydoras and C. cochui are the smallest members of the genus. They are closely followed by C. habrosus (Salt-and-pepper Corydoras) and C. pygmaeus (Pygmy Corydoras)—from Guyana, Suriname, and possibly Peru—with which they are sometimes confused. However, Dwarf Corydoras has a black spot on the caudal peduncle, while C. pygmaeus has a black longitudinal line that runs from the snout to the tail.

Aquarium
- Well planted, with open swimming areas, and fine-grained substratum. Water chemistry not critical, but excessively acid conditions must be avoided. Temperature range: 70-77 F (21-25 C); avoid prolonged exposure to lower temperatures.
