Median longitudinal stripe or row of adjacent black spots on the body, with an unpigmented stripe above it (color pattern may become obscured or faint in larger specimens) (Ref. 43281). Caudal fin with 5-6 indistinct or irregular bars (Ref. 12693).
Facultative air-breathing in the genus (Ref. 126274); Inhabits slow-moving, shallow waters of canals and inundated floodplains (Ref. 12693), usually on or in muddy substrates (Ref. 43281). Lives in swamps and rivers including peats (Ref. 57235). Also found in mountain streams, preferring sandy or gravelly bottom (Ref. 51717). Occurs in running waters of lower Mekong (Ref. 36667). Preferred food is zooplankton but occasionally feeds on some algae. Not seen in markets (Ref. 12693).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00241 - 0.01141), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.7 ±0.31 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
