Short description Bestämningsnycklar | Morfologi | Morfometri

Diagnosis: upper half of caudal fin always with alternating pattern of black and white to yellow stripes; lower half of caudal fin variable in males: uniformly violet (pale and sometimes almost transparent) across entire fin, or with many rows of red spots, or any combination of both; females always with an unmarked, clear to pale violet lower half of the caudal fin (Ref. 52307).

Found in large numbers in areas with slowly-flowing waters along the banks of the Congo River near Brazzaville and Kinshasa; does not seem to prefer the more rapidly-flowing parts of the river, even though Roberts & Stewart (1976) viewed it as a moderately rheophilic species (Ref. 52307). Feeds on worms, crustaceans and insects (Ref. 7020). Cave-spawner (Ref. 52307).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.3 ±0.40 se; based on food items.

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (tm<1. Fec=80-100).

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

Price category (Ref. 80766): Unknown.
