Morphology | Morphometrics
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; 6th soft ray of dorsal fin 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).
Coloration: 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 of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00259 - 0.01467), b=3.09 (2.88 - 3.30), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
