Maturity: Lm ? range ? - ? cm
Max length : 18.6 cm SL самец/пол неопределен; (Ref. 81260)
колючие лучи спинного плавника (общее число) : 15 - 16; членистые (мягкие) лучи спинного плавника (общее число) : 10 - 12; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 9 - 11; позвонки: 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).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.00830 - 0.04177), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (13 of 100).
