Head length 34.0-38.0% SL; lower pharyngeal jaw with unicuspid anterior teeth and straight posterior teeth; ventral keel elongated, as long, or longer, than dentigerous plate; 4-6 rows of teeth in oral jaws, outer row teeth bicuspid (Ref. 81260).Coloration: base body color pale or whitish, light grey dorsally, preorbital olive-green; lips paler than snout; flank scales with central blue-red spot (Ref. 81260). Numerous, irregularly arranged black spots on cheeks (Ref. 52307), opercle (Ref. 52307, 81260) and occiput, concentrated around sensory canal pores (Ref. 81260). Dorsal fin greyish with a large yellowish white distal submargin becoming red marginally; spinous dorsal with some oblique clear lines, very thin between spines, soft dorsal with many clear maculae (Ref. 81260). Caudal fin greyish with many clear maculae, sometimes aligned between rays (Ref. 81260), distal margin red (Ref. 52307, 81260). Anal fin greyish (Ref. 52307, 81260) with some clear maculae between soft rays, proximally tinted red (Ref. 81260). Pelvics whitish to transparent (Ref. 81260). Juveniles: tinted with green, with 6-8 darker vertical bars on the flanks; dorsal, caudal and anal fins greenish grey, with some clear maculae between soft rays; pelvics and pectoral fins transparent (Ref. 81260). Males usually exhibit a red dot at the center of each body scale (Ref. 52307). Trewavas, E. 1983 Tilapiine fishes of the genera <i>Sarotherodon</i>, <i>Oreochromis</i> and <i>Danakilia</i>.

Reports from Gambia and Senegal (Ref. 3538) and Guinea (4517) are doubtful and need confirmation (see Ref. 2, 81260). Also reported from the Cuanza (Angolan coastal) and the southern Congo River basin in Angola (Ref. 120641) but considered a Lower Guinea endemic in Ref. 81260; needs confirmation.

Reproduction is seasonal, usually taking place during the dry seasons from June to September and in February; can reach maturity at a size of 15 cm; breeding behavior is similar to that of its congeners (e.g. O. niloticus) (Ref. 52307).
