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).
与该科的其他成员区分藉由有在臀鳍的基底上面的一列大的眼状斑点.(参考文献 27732) 有别于在背面上的缺乏银色或者金色的横纹中的 C. chitala 与从 C. blanci 与 C. lopis 在没有基部的胸斑点.(参考文献 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).
栖息于大而中等大小河的流动水域。 (参考文献 12693) 在湄公河主流里面，它出现于水池中。 (参考文献 37770) 发现于下面湄公河的整个流域主流了。 (参考文献 36667) 捕食在表层觅食的鱼，甲壳动物与昆虫, 具有一个晨昏或夜行的行为方式。 在时期从六月到十月的高水位的时候移入浸水的森林。 个体从五大湖在泰国被装船运送到市场。 (参考文献 12693)
