More on author: Pellegrin.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic. Tropical; 17°N - 4°N
Africa: restricted to Sassandra and Volta rivers in Côte d'Ivoire and Pra River in Ghana (Ref. 116018).
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 5.7 cm SL male/unsexed; (Ref. 57223)
Dorsal spines (total): 2; Dorsal soft rays (total): 5 - 6; Vertebrae: 31 - 32. Diagnosis: Labial disk moderately developed and rounded, covered with large papillae; mandibular barbels little developed, auxiliary barbels absent; premaxillary teeth large and arranged in 3-4 rows; mandibular teeth numbering 4+4 to 5+5, sometimes even 6+6; dorsal fin with 5-6 branched rays, the 6th soft ray always slender, very close to 5th; adipose fin short, beginning slightly ahead of anal-fin origin; caudal peduncle rather elongate, but less so than in C. batesii; caudal fin deeply forked, with distinctly pointed lobes, lower lobe longer than upper; usually a longitudinal black band on one or both lobes of caudal fin; eyes moderately developed; sexual dimorphism absent or weak (Ref. 57223).
Colouration: body with 3 more or less well defined dark vertical bars separated by paler areas; lower caudal-fin lobe, and sometimes also the upper, with a more or less distinct black band (Ref. 57223).
Oviparous (Ref. 205). Maximum size 6.2cm TL (Ref. 3202).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [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).
Trophic level (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
