Species Profiles

Astronotus ocellatus

Oscars are large, intelligent South American cichlids often called 'water dogs' for their interactive personality. They recognize their owners, beg for food, and can be hand-fed. However, they grow fast, produce massive waste, and need at least a 75-gallon tank.

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.
