Maturity: Lm ? range ? - ? cm
Max length : 50.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 12693)
背棘 (總數) : 1; 背的軟條 (總數) : 7; 臀鰭軟條: 12 - 14; 脊椎骨: 44 - 46. Can be differentiated from its congeners by a unique combination of the following characters: head length 31.0-34.3% SL; dorsal to adipose distance 7.3-10.9% SL; length of dorsal-fin 27.3-30.8% SL; post-adipose distance 14.7-16.2% SL; interorbital distance 28.1-31.1% HL; presence of filamentous extensions on the first three dorsal-fin rays in adults (Ref. 38441). Depressed dorsal fin reaching adipose fin; adipose fin same color as body; body and fins a uniform dark brown; crenulate ridge along anterior edge of pectoral spine; 8 branched anal-fin rays (Ref. 12693). Elongated upper caudal lobe ending in a filament (Ref. 43281).
能被與它的同類區別藉著下列特徵的一個獨特組合: 頭長 31.0-34.3% SL; 背鰭到脂鰭距離 7.3-10.9% SL; 背鰭長 27.3-30.8% SL; 後脂肪的距離 14.7-16.2% SL; 眼間距 28.1-31.1% HL; 在第一個上有絲狀的延長三個背鰭鰭條當成魚時。 (參考文獻 38441) 扁平的背鰭達到脂鰭; 脂鰭相同的顏色當身體; 身體與鰭全深褐色; 細齒狀的脊沿著胸棘的前緣; 8個分枝的臀鰭棘條.(參考文獻 12693) 延長的末端形成一個絲狀突起的上尾部的葉。 (參考文獻 43281)
Inhabits slowly flowing or standing waters of the lower Mekong. Moves into flooded forests during periods of high water levels. Feeds on crustaceans and fishes. Marketed fresh (Ref. 12693).
棲息於下面湄公河的流速緩慢或不流動水域。 在高水位水平的時候移入被水淹沒的森林。 吃甲殼動物和魚類。 在市場上銷售生鮮地了。 (參考文獻 12693)
