Etymology: Symphysodon: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
South America: western Amazon river drainages west of the Purus Arch (Ref. 91098). The ranges of S. aequifasciatus and S. tarzoo are roughly divided by the Purus arch (located between Manaus and Rio Bauana) with only a few S. tarzoo specimens from the Madeira river downstream of the arch, and no S. aequifasciatus specimens from locations upstream of the arch.
