简单描述

背棘 (总数) : 1; 背的软条 (总数) : 7; 臀鳍软条: 12 - 14; 脊椎骨: 43 - 44. Can be differentiated from its congeners by a unique combination of the following characters: adipose fin short (length of adipose-fin base 11.3-12.7% SL; 1.72-2.20 times maximum adipose height) with a steep anterior margin (length of adipose-fin base and a distinct black spot on the posterior half); head width 20.6-23.4% SL; dorsal to adipose distance 12.7-16.2% SL; and absence of filamentous extensions on the first three dorsal-fin rays in adults.
能被与它的同类区别藉着下列特徵的一个独特组合: 脂鳍短 (脂鳍基底 11.3-12.7% SL 的长度; 1.72-2.20 倍最大的脂肪高度) 具有一个陡峭的前缘;(脂鳍基底与一个明显的黑色斑点的长度在后半段上) 头部宽度 20.6-23.4% SL; 背鳍到脂鳍距离 12.7-16.2% SL; 而且在第一个上缺乏丝状的延长三个背鳍鳍条当成鱼时。
Feeds on exogenous insects, aquatic insect larvae, shrimps and other crustaceans, as well as fishes. In Cambodian Mekong, it moves into flooded forest to spawn and the young are first observed in August, with the adults returning to rivers in November and December.
吃外生的昆虫，水生的昆虫幼生，虾与其他的甲壳动物, 以及鱼。 在柬埔寨湄公河，它移入被水淹没的森林产卵，而且幼鱼在八月第一个被观察,藉由被在十一月与十二月回到河的成鱼。
