Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; demersal; potamodromous (Ref. 51243). Tropical
Asia: Bangpakong, Chao Phraya, Meklong, Tapi and Pattani basins in Thailand; Mekong including the Xe Bangfai basin (Laos), peninsular Malaysia, and most larger river basins in Sumatra, Borneo, and Java.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 30.0 cm SL male/unsexed; (Ref. 27732); common length : 15.0 cm SL male/unsexed; (Ref. 57235)
Vertebrae: 42 - 45. Uniform dark grey body; the adipose fin much longer than the anal fin and contiguous with the dorsal fin; very long barbels, with the maxillary barbels reaching to or beyond the caudal-fin base (Ref. 27732). Cranial fontanel extends to base of occipital process (Ref. 12693).
Facultative air-breathing in the genus (Ref. 126274); Found in all types of lowland wetlands (Ref. 57235). Usually associated with slow-flowing, turbid waters and soft bottom (Ref. 27732). Adults feed on insect larvae, zooplankton and small fishes. Move into the flooded riparian forests during periods of high water and returns to rivers during November and December. Oviparous, distinct pairing possibly like other members of the same family (Ref. 205). Usually sold fresh. Commercial foodfish and some aquarium trades (Ref. 57235).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00384 - 0.01800), b=2.95 (2.77 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.8 ±0.59 se; based on food items.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 10,000).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (27 of 100).
