Vertebrae: 29. Diagnosis: profile of the snout evenly decurved, descending to a nearly horizontal mouth; narrow interorbital space (24-27% head length)(Ref. 53949, Ref. 53940). Lower jaw not, or only slightly inclined from the horizontal; lower pharyngeal jaw only slightly longer than wide (Ref. 81260). Dentigerous area of the lower pharyngeal bone longer than the anterior blade in the 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 the dorsal outline; black band of uneven width extending from the opercular spot to the anterior part of the caudal peduncle; posterior end of caudal peduncle with vertical blotch meeting its fellow over the 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 (Ref. 52307).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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 of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00693 - 0.03157), b=2.97 (2.80 - 3.14), 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.
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low vulnerability (11 of 100) .
