Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; potamodromous (Ref. 51243); depth range - m (Ref. ), usually - m (Ref. ). Tropical; 0°C -
Asia: Mekong and Chao Phraya basins.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm SL male/unsexed; (Ref. 30857)
soft rays: 8. Anal fin with 5 branched rays; no black spot on the anterior base of the dorsal fin, but the tip of the fin blackish (Ref. 27732). Gill rakers on first arch 30-33 (Ref. 37829). Silvery color (Ref. 37768).
Occurs in large upland rivers, usually near the bottom of the channel over sand substrate (Ref. 12693). Enters flooded fields (Ref. 12975). Frequently overlooked and rarely recorded due to its rather nondescript appearance and its occurrence along the very bottom of the river over sand substrate. Always found in flowing water and little is known about the migratory habitats of this species. All specimens examined had mouths full of sand which is strained for detritus, diatoms, algae, worms and other organisms. Taken in large numbers by trawls and haul seines in the middle Mekong along the Thai-Lao border (Ref. 12693).
