; süßwasser demersal. Tropical; 10°N - 3°N
Africa: endemic to Lake Barombi Mbo, Cameroon (Ref. 81260).
Größe / Gewicht / Alter
Geschlechtsreife: Lm ?  range ? - ? cm
Max length : 6.7 cm SL Männchen/unbestimmt; (Ref. 53940)
Rückenflossenstacheln (insgesamt) : 14 - 15; Rückenflossenweichstrahlen (insgesamt) : 10 - 12; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 8 - 10; Wirbelzahl: 28 - 29. Diagnosis: mouth strongly upturned, making an angle of about 50° with the horizontal; outer row jaw teeth reduced and few in number, inner row teeth minute tricuspids; lower pharyngeal jaw markedly longer than wide, with a reduced dentigerous surface, and covered with a ‘felt’ of tiny unicuspid teeth (Ref. 81260).
Body shape (shape guide): fusiform / normal.
Prefers open water regions at greater depths, but ventures into the more shallow areas of the lake for spawning, which normally occurs during the rainy season; mainly feeds on phytoplankton and small insects; probably ovophilic mouthbrooder; males occupy a tertitory of ca. 50 cm and it is often possible to find large numbers of males in a limited area (Ref. 52307).
