Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 15 - 17; Dorsal soft rays (total): 9 - 12; Anal spines: 3 - 4; Anal soft rays: 6 - 8. Diagnosis: 21-25 rakers on first gill arch; when stressed with two continuous dark bands on body; 1st dorsal fin spine 30-35% length of fifth spine; caudal fin truncate to subtruncate; dorsal head profile straight; iris yellow to brownish, posterior half sometimes red; upper lip white or pale blue; anterior 2-3 dorsal fin spines with black interspinous membrane in juveniles (Ref. 81260).

Substrate spawning, ovophilic, pair bonding, male mouthbrooding species (Ref. 81260). Both parents take care of the young after hatching (Ref. 47115).

Male mouthbrooder; both parents take care of the young after hatching (Ref. 47115). This corrects previous information from Ref. 26489.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.01274 - 0.01798), b=2.97 (2.92 - 3.02), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 2.6 ±0.2 se; based on diet studies.

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

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).

Price category (Ref. 80766): Unknown.

Chromidotilapia guntheri (Sauvage, 1882)
