Etymology: Oreochromis: Latin, aurum = gold + Greek, chromis = a fish, perhaps a perch (Ref. 45335). More on author: Günther.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
Africa: endemic to Lake Chala (Ref. 52331).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm SL male/unsexed; (Ref. 4967)
(total): 16 - 17;
soft rays: 10 - 16;
Vertebrae: 31 - 34. Diagnosis: teeth very small, in narrow bands; pharyngeal bone narrow, its width about 26% head length, with fine teeth, crowded posteriorly, the blade equal to the median length of the toothed area in young, about 1.5 times as long in adults; pectoral fin usually less than 36% SL (Ref. 2). Scales of chest and belly very small (Ref. 2, 54096), in some individuals showing an abrupt transition from the flank scales for a short distance behind the pectoral-pelvic interspace; in some individuals dorsal scales also small (Ref. 2). Caudal peduncle longer than deep (Ref. 2, 2989, 54096). 3-4 anal fin spines (Ref. 2, 4967). Body at least 2.8 times as long as deep; caudal peduncle at least 1.3 times longer than deep (Ref. 4967).
Inhabits lakes (Ref 2, 4967). Sometimes shoaling (Ref. 36900, 55060). Feeds on algae and debris off the bottom (Ref. 55060).
