Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
Asia: Mekong from the Khorat Plateau, Thailand to the Great Lake, Cambodia (Ref. 12693); Malay Peninsula, coastal streams of South-east Thailand and Cambodia, and Chao Phraya basin in Thailand (Ref. 12041).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.0 cm SL male/unsexed; (Ref. 43281)
soft rays: 8. Two pairs of barbels (Ref. 43281); rostral barbel extends well beyond eye; first pectoral ray sometimes reaching anal fin; narrow dark line from head to caudal-fin base (Re. 12693).
Usually found in ditches, canals and ponds often in areas with extensive growth of submerged aquatic plants (Ref. 12693). Encountered mainly in stagnant water bodies including sluggish flowing canals as well as in medium to large rivers of the middle Mekong (Ref. 12975). Feeds on zooplankton and insects. Sometimes sold fresh and used to make prahoc (Ref. 12693).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00172 - 0.01158), b=3.08 (2.85 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.43 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).
