生态学
; 淡水; 半咸淡水 居于水底的; pH range: 6.0 - 8.0; dH range: 5 - 19. 熱帶; 20°C - 25°C (Ref. 1672); 9°N - 2°N, 9°W - 11°E (Ref. 55202)
Africa: coastal lagoons and lower river courses from the Tabou River (Côte d'Ivoire) to the Kribi River (Cameroon), but absent from the area between the Pra River (Ghana) and Benin (Ref. 53405). Also recorded from the lower Ntem, Cameroon (81260).

Maturity: Lm ? range ? - ? cm
Max length : 32.3 cm SL 雄鱼/尚未辨别雌雄; (Ref. 81260); common length : 17.5 cm TL 雄鱼/尚未辨别雌雄; (Ref. 12193); 最大体重: 1.4 kg (Ref. 40637)
背棘 (总数) : 15 - 17; 背的软条 (总数) : 13 - 15; 臀棘: 3; 臀鳍软条: 10 - 11. Diagnosis: body rather elevated (body depth 46.9-51.6% SL) (Ref. 53405). Head profile rounded (Ref. 81260). Outer teeth on jaws bicuspid (Ref. 53405), gracile (Ref. 81260) and spatulated (Ref. 53405, 81260). Lower pharyngeal jaw teeth relatively small and narrow near posterior border of bone, forming an almost felt-like covering (Ref. 81260). Micro-gillrakers present; adults (> 150 mm) with a series of dark blotches in the middle of the flanks (sometimes body entirely blackish) (Ref. 53405, 81260). Juveniles with 7-9 large vertical bands (Ref. 53405). Ventral scales with central red spot; 12 or more rakers on lower limb of first gill arch (Ref. 81260).
Live in still or flowing waters in rocky or mud-bottom areas (Ref. 44894). Occur in warm springs and mud-bottomed to sand-bottomed canals (Ref. 5723). Clearly prefers a herbivorous diet, including algae, higher plants and parts of cassava, but also accepts insects and shrimps (along with their eggs) (Ref. 52307). Consume plant matter. Reache sexual maturity at 10-15 centimeters length. Parents prepare nest site on logs, leaves and other debris. Prolific species (Ref. 52307). The eggs (600-3300 per female) are guarded by the parents and hatch in 1-3 days. Larvae need 6-8 additional days to develop before they can swim freely (Ref. 52307). Parental care of the brood continues until the fish are about (1.5 cm, Ref. 52307) 2.5-3.0 centimeters (Ref. 44894). Occurs in mixed groups composed of individuals of varying size/age, along with individuals of other species (Ref. 52307). Pair-bonding, open (Ref. 52307) substrate brooder (Ref. 52307, 81260) with both parents guarding the brood (Ref. 52307). Maximum size was recorded at 39.4 cm TL (Ref. 40637).
在岩石的或泥底区域中生活在静止或流动的水域。 (参考文献 44894) 出现于温暖的泉水与泥质底的对砂质底的管.(参考文献 5723) 吃植物事件。 在 10-15 公分长度达成性成熟。 亲鱼在圆木, 树叶与其他的残砾上准备巢位置。 卵 (600-3300 每母鱼) 被由父母保卫而且在 1-3 天内孵化。 亲代养育窝继续，直到鱼是大约 2.5-3.0个公分.(参考文献 44894)
