Etymology: Symphysodon: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335).
Eponymy: This is a name formed by the contraction of ‘Tarpon Zoo’, an ornamental fish export firm in Tarpon Springs, Florida, USA, with a fish collecting station in Leticia, Colombia, from which Earl Lyons’ specimens originated. (Ref. 128868), visit book page.
Environment: milieu / climate zone / depth range / distribution range
Ecology
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.
