Short description Morphology | Morphometrics

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).

Biology     Glossary (e.g. epibenthic)

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). Feed at night on small fish, insects and crustaceans (Ref. 85309). Exhibit parental care, with the male brooding eggs and fry in his mouth (Ref. 85309).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00542 - 0.01399), b=3.06 (2.93 - 3.19), based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.62 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.50; Fec=389).
Prior r = 0.68, 2 SD range = 0.29 - 1.59, log(r) = -0.39, SD log(r) = 0.42, Based on: 1 M, 1 K, 2 Fec records
Vulnerability (Ref. 59153):  Low to moderate vulnerability (26 of 100) .
