Short description Identification keys | Morphology | Morphometrics

Branched dorsal rays 13-15; branched anal rays 6; narrow mouth with narrow and slender jaw (width 8-10% in head length); fleshy lower lips; pale orange caudal fin in life.

Biology     Glossary (e.g. epibenthic)

Occurs in large river habitats (Ref. 12693). Inhabits deep slow reaches during dry season (Ref. 37769). Found in rapid-running mountain streams (Ref. 12975). Not known to migrate, but may probably leave main stream for flooded forests during the periods of high-water. Has not been found in any impoundments. Omnivorous, feeding on detritus and algae along with worms, crustaceans and insects. Marketed fresh (Ref. 12693).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00720 - 0.02306), b=2.98 (2.83 - 3.13), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  2.6   ±0.29 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (21 of 100).
Price category (Ref. 80766):   Unknown.
