Symphysodon aequifasciatus, the blue discus or brown discus, is a
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]
Taxonomy
The taxonomy is disputed, but FishBase follows a review of the genus from 2006.[2][8]
In 2007 it was suggested that the correct scientific name of the blue/brown discus is S. haraldi, whereas S. aequifasciatus is the correct name for the
green discus.[5]
In 2011 a study indicated that it should be split into three: Brown discus (S. aequifasciatus; East Amazon downriver from
Heckel discus (S. discus), but overall they maintain their separate evolutionary trajectories.[4]
