背棘 (總數) : 14 - 16; 背的軟條 (總數) : 10 - 11; 臀棘: 3; 臀鰭軟條: 7 - 8. Diagnosis: lower pharyngeal jaw robust and massive, with a large, heart-shaped dentigerous plate, covered with numerous fine, regularly arrayed teeth; mouth not squared or obtuse; ventral margin of lower lip smooth; ratio of lower jaw length to lower jaw width > 1; oral jaw teeth fixed with non-spatulate crowns (Ref. 26738, 81260). 13-16 gill rakers on first arch (Ref. 26738).
除了 比氏非鯽〔Tilapia bemini〕 與 賽氏非鯽〔Tilapia thysi〕 以外,有別於其他 Bermin 種, 藉著結實的﹐甚至大﹐和低咽的頜具有一個心形的有齒碟覆蓋著了細的, 經常地佈署了齒。 能被與 比氏非鯽〔Tilapia bemini〕 區分顯著地有唇不增大的而且具有一個對下面的唇平滑的下緣.(粗的唇, 具有一個在 T. bemini 中摺疊了而且邊緣了下面唇的下緣) 輕易地與 T. thysi 區分了藉由對寬度 的下頜長度的比",修理, 非竹片狀的口齒 (口的齒細長的, 可移動地深植與具有竹片狀的冠在 T. thysi 中), 與鰓耙數字 (13-16, vs.11-13 在 T. thysi 中).(參考文獻 26738)
Prefers sponges, but small amounts of diatoms, plants (mostly algae) and detritus have also been found in their stomachs (Ref. 52307). Pair-bonding, open (Ref. 52307) substrate brooder/spawner (Ref. 52307, 81260) with both parents guarding the brood (Ref. 52307). Usually spawns in shallow waters, building colonies of up to 6 pairs separated by about 30 cm; eggs are hidden between leaves and pieces of wood (Ref. 52307).
