Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm SL male/unsexed; (Ref. 35381)
Facultative air-breathing in the genus (Ref. 126274); Occurs in rapids where it lives in the rocky anfractuosities in the strong current zones. The length of the male snout bristles might be related with the hierarchic level of the individual within the population. Fished by harpoons or bows in the shallow zones (Ref. 35381).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00712 - 0.03216), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (14 of 100).
