Distinguished from other members of the family by the presence of a row of large ocellated spots above the base of the anal fin (Ref. 27732). Differs from C. chitala in lacking silver or gold transverse streaks on dorsum and from C. blanci and C. lopis in lacking a basal pectoral spot (Ref. 7431).
與該科的其他成員區分藉由有在臀鰭的基底上面的一列大的眼狀斑點.(參考文獻 27732) 有別於在背面上的缺乏銀色或者金色的橫紋中的 C. chitala 與從 C. blanci 與 C. lopis 在沒有基部的胸斑點.(參考文獻 7431)
Obligate air-breathing (Ref. 126274); Inhabits flowing waters of large and medium-sized rivers (Ref. 12693). Within the Mekong mainstream, it occurs in pools (Ref. 37770). Found in the basin-wide mainstream of the lower Mekong (Ref. 36667). A predator on surface-feeding fishes, crustaceans and insects, with a crepuscular or nocturnal activity pattern. Moves into inundated forest during the high water period from June to October. Individuals from the Great Lake are shipped to markets in Thailand (Ref. 12693).
棲息於大而中等大小河的流動水域。 (參考文獻 12693) 在湄公河主流裡面，它出現於水池中。 (參考文獻 37770) 發現於下面湄公河的整個流域主流了。 (參考文獻 36667) 捕食在表層覓食的魚，甲殼動物與昆蟲, 具有一個晨昏或夜行的行為模式。 在時期從六月到十月的高水位的時候移入浸水的森林。 個體從五大湖在泰國被裝船運送到市場。 (參考文獻 12693)
