Bifurcate or even multifurcate lateral-line tubes; 4 barbels; 16-20 gill rakers on first arch (Ref. 12693); very long dorsal spine (Ref. 43281).

Occurs at midwater to bottom levels of rivers (Ref. 12693). Feeds mainly on bivalves, roots of plants, zooplankton and green algae (Ref. 6459). Young are known to feed on zooplankton while adults prey also on insect larvae, crustaceans and fish (12693). Lives in rivers and spawns during the rainy season, probably on the floodplains or inundated riparian forests. Returns to the rivers from October to December. Does not occur in impoundments (Ref. 12693). A strongly migratory species which lives in the mainstream and larger tributaries of the Mekong (Ref. 9497). Found in the basin-wide mainstream of the lower Mekong (Ref. 36667). In the Mekong, it undertakes an upstream migration from Phnom Penh to Khone Falls from November to February, and a downstream migration from May to August. This migration continues down to the Mekong delta area in Viet Nam, where it continues until the peak of floods in October-November. These two migrations mainly constitute juveniles and sub-adults, although adults of 90 cm are reported very near the Khone Falls. Above the Khone Falls, upstream migrations occur from April to September which are dominated by adult fishes and probably these are spawning migrations because of the presence of mature fishes bearing eggs (Ref. 37770). These upstream migrations above the Khone Falls are reported to be triggered by the first rainfall at the end of the dry season, rising of water levels and higher turbidity (Ref. 37770). A desirable food fish, marketed fresh (Ref. 12693).
生存在河的中層水域到底區。 (參考文獻 12693) 主要吃二枚貝，植物，浮游動物與綠藻的根。 (參考文獻 6459) 已知幼魚捕食浮游動物雖然成魚也吃昆蟲幼生，甲殼類動物和魚類。 (12693) 生活在河而且在雨季的時候產卵, 可能在洪泛區或浸水的河岸森林上。 從十月到十二月回到河。 不會出現在圈圍水域.(參考文獻 12693) 生活在主流與湄公河的較大的支流中的一個強烈的迴游性種.(參考文獻 9497) 發現於下面湄公河的整個流域主流了。 (參考文獻 36667) 在湄公河中，它進行一個從金邊到 Khone 瀑布的溯溪迴游從十一月到二月, 與一個向下游的遷移從五月到八月。 這遷移繼續向下至在越南的湄公河三角州區域, 在那裡它在十月至十一月繼續到洪水的高峰。 這兩個迴游主要地構成稚魚與亞成魚, 雖然 90 公分的成魚被報告非常接近 Khone 瀑布。 在 Khone 瀑布之上，向上游的迴游出現從四月到九月那是被成魚控制，而且可能這些被生殖迴游由於那有生長著卵的成熟的魚.(參考文獻 37770) 在 Khone 瀑布上面的這些個向上游的迴游被報告在乾季末端經由第一個降雨所引起, 水位上升而混濁度提高.(參考文獻 37770) 一個令人滿意的食用魚, 在市場上銷售生鮮地了。 (參考文獻 12693)
