Max length : 150 cm TL male/unsexed; (Ref. 4833); common length : 40.0 cm TL male/unsexed; (Ref. 4833)
soft rays: 11 - 12. Body elongate and compressed; snout broad and spatulate. Barbels extend posteriorly to pelvic fins or beyond to anal fin. Dorsal spine weakly serrated on its posterior edge; adipose fin base short, about as long as the rayed dorsal fin base. Color is brownish-gray on back, silvery on flanks and belly. A dark well-defined spot is on the adipose dorsal fin.
Found in rivers, canals, beels, ditches, inundated fields and other freshwater areas. Adults fight well and provide good sport. Carnivore. Breeding occurs before the commencement of monsoons. Oviparous, distinct pairing possibly like other members of the same genus (Ref. 205).

Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00382 - 0.00907), b=2.96 (2.84 - 3.08), based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic Level (Ref. 69278
): 3.8 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Fec = 20,064).
Vulnerability (Ref. 59153
