Species Profiles
Congo Tetra
Phenacogrammus interruptus
Congo tetras are the showstoppers of the tetra family. Males develop spectacular flowing fins with an iridescent rainbow sheen that shifts from blue to gold to green under aquarium lighting. They are larger than most tetras (up to 3.5 inches) and need a spacious, well-planted tank to display their full beauty. Peaceful but shy — they thrive with calm tank mates.

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.
