Size / Weight / سن
Maturity: Lm ? range ? - ? cm
Max length : 18.6 cm SL جنس نر / بدون خواص جنسي; (Ref. 81260)
خارهاي باله پشتي (کل) : 15 - 16; شعاع نرم باله پشتي (کل) : 10 - 12; خارهاي باله مخرجي: 3; شعاع نرم باله مخرجي: 9 - 11; مهره ها: 29 - 30. Diagnosis: 17-20 rakers on lower limb of first arch; length of lower pharyngeal jaw < 43.5% of head length; 30-32 scales in lateral line; head length 39-48% of standard length (Ref. 81260). Toothed area of lower pharyngeal jaw contained 2-3 times in length of ventral keel (Ref. 2, 81260). Total dorsal rays (including spines) 26-28 (Ref. 81260). General color dull grey; breeding (or spent?) males with black or grey smudges; no tilapia-mark, at least 6.2 cm SL or over (Ref. 2).
The young of the species are more carnivorous than the adults; the latter feed predominantly on phytoplankton (Ref. 2). Lacks marked sexual dichromatism when sexually active; forms temporary pair bonds (Ref. 81260).
