''Heros'' is a genus of cichlids native to rivers in the Amazon and Orinoco basins in South America. These were often previously included in the "catch-all" genus ''Cichlasoma''. Most commonly encountered in the aquarium trade is ''Heros severus'', available commercially in its gold coloration as well as the wild-type green. It is unclear whether aquarium severums are actually ''H. severus'' or whether they are ''Heros efasciatus'' hybrids. Fish belonging to the genus ''Heros'' are distinguishable by their bulbous "Dell 'Abate" lips and sedentary demeanor, especially after eating. ==Species== There are currently 5 recognized species in this genus: * ''Heros efasciatus'' Heckel, 1840 * ''Heros liberifer'' Staeck & I. Schindler, 2015 〔Staeck, W. & Schindler, I. (2015): Description of a new ''Heros'' species (Teleostei, Cichlidae) from the Rio Orinoco drainage and notes on ''Heros severus'' Heckel, 1840.
