Africa: present in the basins of the Ogooué, Nyanga, Kouilou-Niari and Chiloango, Gabon to Democratic Republic of the Congo (Ref. 2, 81260). Reports from Gambia and Senegal (Ref. 3538) and Guinea (4517) are doubtful and need confirmation (see Ref. 2, 81260). Also reported from the Cuanza (Angolan coastal) and the southern Congo River basin in Angola (Ref. 120641) but considered a Lower Guinea endemic in Ref. 81260; needs confirmation.
非洲: 上、下奧克維河與它的支流伊溫多河; Chiloango 系統; Niari Kouilou。 也記錄自甘比亞與塞內加爾 (參考文獻 3538) 與幾內亞。 (4517)

Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼
Nests are made on sandy or loamy bottoms in water 40-80 cm deep, or more sparsely in depths of a meter or more; they are circular basins with a diameter of 115-185 cm, about 20 cm deep in the middle with a rim raised 7-8 cm above the surrounding level; spawning occurs at night, the fishes seeking deeper waters during the day to avoid high temperatures and intense illumination (Ref. 2). Reproduction is seasonal, usually taking place during the dry seasons from June to September and in February; can reach maturity at a size of 15 cm; breeding behavior is similar to that of its congeners (e.g. O. niloticus) (Ref. 52307).非洲: 上、下奧克維河與它的支流伊溫多河; Chiloango 系統; Niari Kouilou。 也記錄自甘比亞與塞內加爾 (參考文獻 3538) 與幾內亞。 (4517)
