White dorsal, anal and caudal margins; 3-3+1/2 scales between the lateral line and the base of the anterior dorsal rays; relatively small size (Ref. 27732).
Obligate air-breathing (Ref. 126274); Found in hill streams (Ref. 27732). Adults inhabit medium to large rivers, brooks, rapid-running mountain streams and stagnant water bodies including sluggish flowing canals (Ref. 12975).

= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00695 - 0.01143), b=2.99 (2.93 - 3.05), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.62 se; based on food items.
Generation time: 2.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.50; Fec=389).
Fishing Vulnerability (Ref. 59153
): Low to moderate vulnerability (26 of 100).
