Short description
Bestämningsnycklar | Morfologi | Morfometri
This species is characterized by the following: length of rostral barbels 4.0-5.1% HL; lateral line scales 50-60; circumpeduncular scales 22-27; scales from the lateral line to the anal-fin origin 61/2-71/2 (Ref. 118635).
Inhabits relatively still waters and occurs in deep pools in larger rivers and in most low-country reservoirs. Feeds mainly on algae. Breeding in rivers is highly influenced by monsoon rains (Ref. 43628).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00434 - 0.02104), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
