خارهاي باله پشتي (کل): 15 - 16; شعاع نرم باله پشتي (کل): 10-11; خارهاي باله مخرجي 3; شعاع نرم باله مخرجي: 8 - 9; مهره ها: 29. Diagnosis: profile of the snout evenly decurved, descending to a nearly horizontal mouth; narrow interorbital space (24-27% head length)(Ref. 53940, 53949). Lower jaw not, or only slightly inclined from the horizontal; lower pharyngeal jaw only slightly longer than wide (Ref. 81260). Dentigerous area of lower pharyngeal bone longer than anterior blade in young and of characteristic shape, with a narrow anterior apical portion (Ref. 53949). Blade of lower pharyngeal bone 0.7-0.95 times median length of toothed area; 3 regular rows of teeth; upper series of black blotches parallel to dorsal outline; black band of uneven width extending from opercular spot to anterior part of caudal peduncle; posterior end of caudal peduncle with vertical blotch meeting its fellow over top; fins colorless; tilapia mark absent (Ref. 53940).
Feeds on algae, small insects and fish eggs (Ref. 52307). Also kleptoparasite of freshwater crabs (Ref. 53950). Ovophilic mouthbrooder with both sexes as possible incubator; from aquarium observations: a few days prior to spawning, both partners remain close together for much of the time; the genital papilla of the female is clearly visible immediately before spawning and is much broader and larger than the male's; females are normally more successful than males when it comes to brooding the fry; when mouthbrooding, which ends about 3 weeks post-spawning, the specimens are relatively shy and prefer to lie silently near the bottom in secluded areas; once free swimming, juveniles normally do not return to the parent's mouth again (Ref. 52307).
Life cycle and mating behavior

Male or female carries the egg in the mouth (Ref. 52307, Ref. 13614). A few days prior to spawning, both partners remain close together for much of the time; the genital papilla of the female is clearly visible immediately before spawning and is much broader and larger then the male's; females normally more succesfull in brooding the fry; specimens are relatively shy and prefer to lie silently near the bottom in secluded areas when mouthbrooding, which ends about three weeks post-spawning; once free swimming, the fry normally does not return to the parent's mouth (Ref. 52307).
