Occurs in the main stream of the middle Mekong during dry season (Ref. 12693) in deep slow reaches (Ref. 37769). Migrates to smaller streams or floodplains during rainy season (Ref. 12693). Found also in rapid-running mountain streams (Ref. 12975). Omnivorous, feeding on detritus, periphyton, worms and insects. Breeding occurs at the end of the rainy season, as water levels fall. Marketed fresh (Ref.12693).
在深且和緩的河段中在乾季 (參考文獻 12693) 的時候出現於湄公河中游的主要水流。 (參考文獻 37769) 在雨季的時候迴游到較小的溪流或洪泛區。 (參考文獻 12693) 也發現於湍急的山地溪流了。 (參考文獻 12975) 雜食性,吃碎屑，固著生物，蠕蟲與昆蟲。 在雨季結束的時候繁殖, 如同水位下降。 在市場上銷售生鮮地了。 (參考文獻 12693)
