Blue Emperor / Super Blue Kerri Tetra (Inpaichthys kerri)

A colorful, smaller growing characin known from the upper Rio Madeira in Brazil, the Blue Emperor or Super Blue Kerri Tetra is deservedly popular in the aquarium hobby and has been commercially bred for years to the point where wild collected specimens are almost never exported. In the wild, they inhabit slow moving, warm, acidic streams but will adapt to a wide range of conditions in the aquarium. Like most of their close relatives, they are a loosely schooling species that will do best in groups of 5 or more and will get along well with most similarly sized, peaceful tankmates. Subdued lighting, plenty of cover in the form of driftwood or plants, and slightly soft water will help promote vibrant coloration.
