Environment: milieu / climate zone / depth range / distribution range
Écologie
; eau douce démersal. Tropical
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).
Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 37.0 cm TL mâle / non sexé; (Ref. 5163)
Épines dorsales (Total) : 16 - 17; Rayons mous dorsaux (Total) : 11 - 14; Épines anales: 3; Rayons mous anaux: 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
Phylogenetic diversity index (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).
Niveau trophique (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
Résilience (Ref.
