Species Profiles
Pygmy Corydoras
Corydoras pygmaeus
beginnerpeaceful10+ gal
Pygmy corydoras are tiny, adorable catfish that max out at just 1 inch. Unlike other corys that stay on the bottom, pygmy corys are unique in that they frequently swim in the mid-water column, hovering in groups like tiny helicopters. They are perfect for nano tanks and shrimp tanks, and their micro-schooling behavior is endlessly entertaining.
