Species Profiles
Pygmy Corydoras
Corydoras pygmaeus
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.

Hillstream loaches are fascinating flat-bodied fish that resemble tiny stingrays. They are specialized for life in fast-flowing, oxygen-rich streams and use their modified pelvic and pectoral fins to grip smooth rocks in strong current. Their unique appearance, algae-eating habits, and cool-water preference make them popular with experienced fishkeepers looking for something different.
