Etymology: Oreochromis: Latin, aurum = gold + Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; brackish; benthopelagic. Tropical; 24°C - 26°C (Ref. 2059); 3°S - 9°S
Africa: Lake Tanganyika, in the coastal area and river mouths.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 42.0 cm SL male/unsexed; (Ref. 4967)
(total): 15 - 17;
Vertebrae: 30 - 31. Jaws not prolonged. Preorbital bone deep, 24-29 % HL. Scales of chest and belly very small but imbricating. Melanin pattern of body in facultative vertical bands of constant width, usually invisible in large preserved fishes.
Sometimes forms schools. Has been reported to browse on the surface film of sheltered waters. Stomachs contained large quantities of the diatoms Pinnularia and Navicula with some sand grains (Ref. 2).
