Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
Africa: endemic to Lake Bermin, Cameroon (Ref. 52307, 81260).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.0 cm SL male/unsexed; (Ref. 81260)
(total): 15 - 16;
soft rays: 7 - 8. Diagnosis: lower pharyngeal jaw robust, with a large, triangular (not heart-shaped) dentigerous plate, covered with stout, sparsely arrayed teeth; oral dentition coarse; outer row teeth stout bicuspids (Ref. 26738, 81260). Anterior rakers not markedly reduced in size; snout acute (Ref. 81260). Ventral margin of lower lip smooth; 10-12 slender gill rakers (Ref. 26738, 81260). Ratio of lower jaw length to lower jaw width > 1 (Ref. 81260). 1-2 inner rows of teeth on both jaws (Ref. 26738, 81260).
Feeds primarily on vegetative matter (preferably algae), but also takes detritus, insects, diatoms and small amounts of sponges (Ref. 52307). A dwarf species, with females reaching sexual maturity at 25 mm SL, making this the smallest tilapiine known (Ref. 26738, 52307). The number of eggs produced is accordingly small, with 10-20 eggs usually deposited, preferably in shallow water on various substrates; large colonies composed of many pairs have been observed (Ref. 52307). Pair-bonding, open (Ref. 52307) substratum brooder (Ref. 52307, 81260), with both parents guarding the brood and fry (Ref. 52307).
