Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 17; Dorsal soft rays (total): 7 - 8; Anal spines: 3; Anal soft rays: 8; Vertebrae: 26. Distinguished from all other cichlids by its color pattern and its short, low vertical fins. Presence of a series of 8 dark vertical markings, the anteriormost through the eye, the fourth from anteriormost bearing a large midlateral blotch; the fins are immaculate (Ref. 26742).

Both parents tend the clutch. Larvae are often deposited in little holes in the roots.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.03020 (0.01346 - 0.06774), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (tm<1).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
