Discus fish (Symphysodon genus) are a genus of three species of cichlid freshwater fishes native to the Amazon River basin. They are popular as aquarium fish and in aquaculture. Discus fish belong to the genus Symphysodon, which includes three species: the Common Discus (Symphysodon aequifasciatus), the Heckel Discus (Symphysodon discus) and Symphysodon tarzoo.

Like cichlids, all Symphysodon species have a laterally compressed body shape, and rounded shape from which their name discus is derived. The sides of the fish are patterned in shades of green, red, brown, and blue.
