Μέγεθος / Βάρος / Ηλικία
Γεννητική Ωρίμανση: Lm ?  range ? - ? cm
Max length : 9.3 cm TL αρσενικό/απροσδιόριστο; (Ref. 4984)
Ραχιαίες άκανθες (συνολικά) : 15 - 16; Μαλακές ραχιαίες ακτίνες (συνολικά) : 10 - 11; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 8 - 9; Σπόνδυλοι: 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).
Body shape (shape guide): fusiform / normal.
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).

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).
