背棘 (總數): 15 - 16; 背的軟條 (總數): 10-11; 臀棘 3; 臀鰭軟條: 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).
除了 巴可非鯽〔Tilapia bakossiorum〕 以外有別於其他 Bermin 種, 黃非鯽〔Tilapia flava〕 與
覆蓋著的具有三角形的有齒碟結實低的咽頜的 綿非鯽〔Tilapia spongotroktis〕 矮胖的, 稀疏地佈署了齒。 在唇形態學中與 巴可非鯽〔Tilapia bakossiorum〕 區分了: 不顯著地肥大的有平滑的對下唇的邊緣,vs. 唇肥大的以下唇邊緣摺疊而且邊緣。 在口的生齒有別於 黃非鯽〔Tilapia flava〕 : 矮胖的, 厚的-頸部了二頭齒, vs. 細長的, 藉由斜截形的冠。 在上頜與下頜與鰓耙形態學 (細長的, vs. 肉質的具有連接外部而內部的列耙的細齒狀的中央薄膜) 的 綿非鯽〔Tilapia spongotroktis〕 , 與內部列的齒的數字區分了。 (1-2 雙顎內, vs.2-4 在上面的與 2-3 在下頜中) 一個矮小的種, 與雌性在 25 mm SL 達成性成熟, 發表。 (參考文獻 26738)
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).
