Occurs in rivers, streams and lakes as well as in impoundments (Ref. 12693). A migratory species (Ref. 37772). Undertakes lateral migrations from the Mekong River into smaller tributaries and into the floodplains at the start of the flood season, returning back to the main river channel when the water begins to recede at the onset of the dry season (Ref. 37770). Migrations are triggered by the first rainfall at the end of the dry season, as well as water level changes. Lunar cycle affects also the movements. Returns to the river from the floodplain and tributaries on, or immediately before, the full moon (Ref. 37770). Feeds on small fishes, shrimps and aquatic insect larvae (Ref. 6459).
出現於河，溪流與湖以及在圈圍水域.(參考文獻 12693) 一個迴游的種.(參考文獻 37772) 進行橫向的迴游從湄公河進入較小的支流與洪泛區在那洪水季節的初始, 游回主要的河峽道當水開始後退的時候在乾季的開始.(參考文獻 37770) 迴游在乾季末端被第一個降雨引起, 以及水位改變。 陰曆的周期也影響運動。 回到河從洪泛區與支流,之上或在,正前方月圓.(參考文獻 37770) 吃小魚，蝦與水生的昆蟲幼生。 (參考文獻 6459)
