Maturity: Lm ? range ? - ? cm
Max length : 18.5 cm SL jantan/; (Ref. 81260)
Duri punggung (Keseluruhan (total)) : 14 - 16; duri punggung lunak (Keseluruhan (total)) : 10 - 12; Duri dubur: 3; Sirip dubur lunak: 8 - 11; vertebrata, bertulang belakang: 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).
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 (Ref. 2). Adults feed predominantly on phytoplankton (Ref. 2, 52307). Congregates in small groups (under 10 individuals) in open water regions and at a maximum depth of about 5 m (Ref. 52307). Lacks marked sexual dichromatism when sexually active (Ref. 81260). Ovophilic, maternal mouth brooder (Ref. 52307) that forms temporary pair bonds (Ref. 81260) prior to spawning, but none after (Ref. 52307). Ventures to regions near the edges of the lake for spawning, where the male constructs craters in the sand; males infrequently incubate the eggs (Ref. 52307).
Brooding by both sexes, predominantly by the female.
