Morphology | Morphometrics
(total): 14 - 16;
soft rays: 8 - 11;
Vertebrae: 29. Diagnosis: 15-20 rakers on lower limb of first arch; 30-32 scales in lateral line (Ref. 81260). Body dark grey or green (Ref. 2, 81260). Head large, especially in adults (Ref. 2), its length 37-45% of standard length (Ref. 81260). Jaw teeth very small (Ref. 81260). Breeding males green; intense tilapia-mark present in young until about 10 cm SL, absent above 15 cm SL; as the gonads mature the lower parts of the head and the flanks become more metallic and green; most brooding females silver grey in general color; fins mainly of a neutral color; pelvic fins may be yellow (Ref. 2).
Africa: endemic to Lake Barombi Mbo, West Cameroon (Ref. 4999, 81260).
Occasionally forms schools; is mainly diurnal; juveniles feed on mayfly larvae and various terrestrial insects among a diet in which animal items formed a high proportion; adults feed predominantly on phytoplankton (Ref. 2). Lacks marked sexual dichromatism when sexually active; forms temporary pair bonds (Ref. 81260).
