Source: From Wikipedia, the free encyclopedia
Discus are freshwater perciform fish, peculiar cichlids native to the Amazon River basin. There are two recognized species, both within the genus Symphysodon: the red discus or common discus (Symphysodon discus) and the blue discus (Symphysodon aequifasciatus). The two species are very similar and may interbreed, producing a number of hybrid strains. Details regarding the precise number of subspecies have not been finalised. Discus are most closely related to the genus Heros.
