Africa: coastal zone around the Ogooué, Kouilou-Niari and Chiloango (Ref. 81651) up to the mouth of the Congo River (Ref. 55074, 74387). Reported from around the Cuanza delta in Angola (Ref. 5163), but Cuanza specimens identified as Tilapia cf. cabrae in Ref. 120641; may need verification. Also reported from the Bengo River in Angola (Ref. 120641) and from southern Equatorial Guinea (Ref. 5163, 52307).
Grootte / Gewicht / Leeftijd
Maturity: Lm ? range ? - ? cm
Max length : 37.0 cm TL mannelijk / geslacht onbekend; (Ref. 5163)
Dorsale stekels (totaal): 16 - 17; Dorsale zachte stralen (totaal): 11-14; Anale stekels 3; Anale zachte stralen: 9 - 11. Diagnosis: 12 or more rakers on lower limb of first gill arch; outer row jaw teeth gracile and somewhat spatulate; adults with dark, broad vertical stripes on flanks; ventral scales with small irregular red-brown spots; head profile straight; lower pharyngeal jaw with relatively strong teeth not forming a felt-like covering (Ref. 81260).
Maximum standard length reported is 37.0 cm (Ref. 81260). Probably pair bonding (Ref. 52307). Open (Ref. 52307) substrate brooder/spawner (Ref. 52307, 81260) with both parents guarding the brood (Ref. 52307).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00827 - 0.04391), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (27 of 100).
Nutrients (Ref.
124155): Calcium = 139 [68, 245] mg/100g; Iron = 1.59 [0.83, 3.39] mg/100g; Protein = 18.4 [16.8, 19.9] %; Omega3 = 0.34 [0.13, 0.97] g/100g; Selenium = 77.3 [31.2, 173.6] μg/100g; VitaminA = 17.9 [4.5, 57.5] μg/100g; Zinc = 1.64 [1.07, 2.54] mg/100g (wet weight);
