Short description Identification keys | Morphology | Morphometrics

Diagnosis: body depth 4.7-6.2 and head length 3.1-3.8x SL; caudal peduncle 1.5-2x longer than high; head flattened, 2.9-3.5 longer than wide; eye diameter 4-7x of head length; scale formula 12.5-14.5/90-107/13.5-14.5; single, dark, undulating longitudinal band along lateral line (not visible in live specimens); caudal-fin lobes marked with oblong black spots (Chad and Benué) (Ref. 2936, 86396).

Maximum TL was recorded at 24.5 cm (Ref. 7094). Inhabits open water and fringing vegetation. Feeds on Caridina and fish fry (Ref. 28714).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00447 (0.00189 - 0.01058), b=3.17 (2.96 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.3 se; based on diet studies.

Generation time: 1.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (K=0.6).

Fishing Vulnerability (Ref. 59153): Low vulnerability (23 of 100).
