Etymology: Oreochromis: Latin, aurum = gold + Greek, chromis = a fish, perhaps a perch (Ref. 45335); lepidurus: From the Greek "lepis" = scale and "oura" = tail, referring to the densely scaled caudal fin (Ref. 55074).

Body shape (shape guide): short and / or deep; Cross section: compressed.
Microphagous, using plankton (Ref. 2, 55074). Maternal, ovophilic mouthbrooder (Ref. 52307).
