Short description Morphology | Morphometrics

Dorsal spines (total): 14 - 17; Dorsal soft rays (total): 11-13; Anal spines: 3; Anal soft rays: 9 - 12; Vertebrae: 29 - 30. Breeding males with the edges of the dorsal and caudal fins orange or red. 2-4 large, vaguely outlined dark blotches mid-laterally from operculum to caudal peduncle and a blotch on top of caudal peduncle. Caudal rays rather densely scaled to near edge. Caudal peduncle deep.

Feeds on the soft, flocculent bottom deposits which consist of finely divided plant material (Ref. 2), algae, detritus (Ref. 52307), protozoa and bacteria (Ref. 2, 52307). Female mouthbrooder (Ref. 27292).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Female broods the young and eggs in the mouth in the shelter of sandbanks in the Zaire of Yangambi.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01622 (0.00707 - 0.03721), b=3.02 (2.82 - 3.22), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 2.5 ±0.24 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100) .
