Native to the Amazon River basin, Discus Fish are a type of South American Cichlid. These fish tend to inhabit the floodplains, lakes and rivers throughout the Amazon River Basin. There are currently three recognized species of Discus Fish: Symphysodon discus (the Heckel Discus), Symphysodon aequifasciatus (the common Discus) and Symphysodon tarzoo. Each species has its own specific geographic distribution. The Heckel Discus lives primarily in the lower Rio Negro as well as the Abacaxis and Trombetas rivers. The Common Discus can be found throughout Brazil, Columbia and Peru while Symphysodon tarzoo is generally only found in portions of the western Amazon.
