Symphysodon aequifasciatus, the blue discus or brown discus, is a species of cichlid native to rivers of the eastern and central Amazon Basin downriver from the Purus Arch.[2] This discus is found in black-, clear- and whitewater,[2][3] but its preference for lentic habitats such as floodplains and flooded forests means that the whitewater it inhabits contain little suspended material (unlike main sections of whitewater rivers).[4] It is largely restricted to water with a high temperature of 25–32 °C (77–90 °F) and a pH of 5.2–7.7.[5]
It typically reaches a length of up to 15.2 centimetres (6 in) SL,[3] but captives have been claimed to reach 23 cm (9 in).[6] It is commonly kept in aquariums.[7]
