Heros is a genus of cichlids native to the Amazon, Orinoco and Essequibo River basins in South America.

[1] They were previously included in the genus Cichlasoma before its restriction to the distinct group of "Port 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.

Rotkeil ("Red Shoulder") is thought by hobby specialists to represent an undescribed Heros species.
