Corydoras Pygmaeus

Corydoras Pygmaeus, commonly known as the pygmy corydoras or pygmy catfish, is a tropical freshwater fish that sits among the smallest, most intriguing members of the Corydoradinae subfamily in the Callichthyidae family. Its compact presence brings a touch of South American river life into your tank without dominating the aquascape.

This species originates in tropical inland waters of South America and is specifically found in the Madeira River basin in Brazil. That regional origin makes Corydoras Pygmaeus a meaningful choice for hobbyists seeking an authentic representation of Brazilian freshwater biodiversity in a home aquarium.
