duri punggung lunak (Keseluruhan (total)) : 10; Sirip dubur lunak: 21 - 23; vertebrata, bertulang belakang: 36 - 38. A conspicuous dark blotch present at the humeral region. Scales rows between dorsal-fin origin and anal-fin origin 7-8. Mature males with anal-fin gland cup-shaped, its lower part much more developed than the upper (Ref. 81197).

Occurs in clear water rocky rapids, with thick sand on the bottom. Forms small schools of about 10-15 individuals actively swimming against fast flowing waters below a one meter high fall (Ref. 81197).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01413 (0.00635 - 0.03140), b=2.99 (2.80 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
