Tamanho / Peso / Idade
Maturidade: Lm ? range ? - ? cm
Max length : 18.6 cm SL macho/indeterminado; (Ref. 81260)
Espinhos dorsais (total) : 15 - 16; Raios dorsais moles (total) : 10 - 12; Espinhos anais: 3; Raios anais moles: 9 - 11; Vértebras: 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).
Body shape (shape guide): short and / or deep.
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).
