''Symphysodon'' species inhabit the margins of floodplain [[lake]]s and [[river]]s in the lowland [[Amazon basin]],<ref name=Campton2008/> where they are part of the highly diverse [[Neotropical fishes|Neotropical fish]] fauna. ''S. discus'' is restricted to [[Blackwater river|blackwater]] habitats, but periodically these may experience brief floods of [[Whitewater river (river type)| |

''S. discus'' is restricted to [[Blackwater river|blackwater]] habitats, but periodically these may experience brief floods of [[Whitewater river (river type)|white water]].<ref name=Bleher2007/> ''S. tarzoo'' is found in both black<ref name=Bleher2007/> and white water,<ref name=ready2006/> and ''S. aequifasciatus'' also occurs in [[Clearwater river (river type)|clearwater]].<ref name=Bleher2007/> Because of their preference for [[lentic]] habitats such as floodplains and [[flooded forest]]s, white water inhabited by discus contains little suspended material (unlike main sections of whitewater rivers).<ref name=Amado2011/> |

The three species of ''Symphysodon'' have different geographic distributions. ''S. aequifasciatus'' occurs in the East Amazon downriver from the [[Purus Arch]] and ''S. tarzoo'' in the West Amazon upriver from the Purus Arch.<ref name=ready2006/> In contrast, the distribution of ''S. discus'' appears to be limited to the lower reaches of the [[Rio Negro (Amazon)|Rio Negro]], upper [[Uatumã River|Uatumã]], [[Nhamundá River|Nhamundá]], [[Trombetas River|Trombetas]] ,and [[Abacaxis River]]s.<ref name=ready2006/><ref name=Amado2011/> |
