簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 1; 背的軟條 (總數): 7; 臀鰭軟條: 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.
能被與它的同類區別藉著下列特徵的一個獨特組合: 脂鰭短 (脂鰭基底 11.3-12.7% SL 的長度; 1.72-2.20 倍最大的脂肪高度) 具有一個陡峭的前緣;(脂鰭基底與一個明顯的黑色斑點的長度在後半段上) 頭部寬度 20.6-23.4% SL; 背鰭到脂鰭距離 12.7-16.2% SL; 而且在第一個上缺乏絲狀的延長三個背鰭鰭條當成魚時。
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.
吃外生的昆蟲，水生的昆蟲幼生，蝦與其他的甲殼動物, 以及魚。 在高棉湄公河，它移入被水淹沒的森林產卵，而且幼魚在八月第一個被觀察,藉由被在十一月與十二月回到河的成魚。

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
