Quick Facts Heros, Scientific classification ...

The Heros species most commonly encountered in the aquarium trade are fish referable to the species Heros efasciatus. However, the trade name generally used is "Severum Cichlids." Trade fish are very often line bred specimens of color sports such as "Super Red Severums" or "Gold Severums." The provenance of these is not clear, but they seem to have been derived from the base "Green Severum" form that is most closely identified with H. efasciatus.

Species

There are currently five recognized species in this genus:[2]

Many authorities also cite a previously described species, Heros appendiculatus. It has a form quite distinct from H. efasciatus but was synonymized with H. efasciatus by Dr. Sven O. Kullander. Another color form, Heros sp. Rotkeil ("Red Shoulder") is thought by hobby specialists to represent an undescribed Heros species.
