African Glass Catfish
Pareutropius debauwi
Key differences: Though also a schooling African fish, the African Glass Catfish is easily distinguished by its translucent body and the presence of barbels around its mouth, which are absent in Congo Tetras. It also belongs to a different family (Schilbeidae).

Key differences: There are other species within the genus Phenacogrammus, but P. interruptus is uniquely characterized by the combination of its specific iridescent color pattern and the highly elongated, flowing fins of the males. Careful examination of fin structure and coloration patterns is necessary for differentiation.
