Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm SL maschio/sesso non determinato; (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): PD
50 = 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).
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (14 of 100).
