; süßwasser benthopelagisch. Tropical; 25°C - 27°C (Ref. 13614); 10°N - 3°N

Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 9.3 cm TL Männchen/unbestimmt; (Ref. 4984)
Rückenflossenstacheln (insgesamt): 15 - 16; Rückenflossenweichstrahlen (insgesamt): 10-11; Afterflossenstacheln 3; Afterflossenweichstrahlen: 8 - 9; Wirbelzahl: 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).

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).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.45 se; based on food items.
Widerstandsfähigkeit (Ref.
120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
