Maturity: Lm ?  range ? - ? cm
Max length : 5.8 cm SL male/unsexed; (Ref. 37395)
Very abundant. Lives in the upper reaches of rivers (Ref. 35381). Frequently occurs over sandy bottoms traversed by strong currents. Most probably lives in schools as it is often captured in groups (Ref. 27188). Often found with C. approuaguensis and C. cf. brevirostris (Ref. 35381).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.3 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.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
