在比大约 15 公分 SL 大的标本中的鲜红色尾鳍; 微白色的在较小的一些中.(参考文献 27732) 脂鳍长的 (脂鳍基底 18.7-25.7% SL 的长度), 具有一个缓斜坡的前缘; 背棘钙化不足与在后缘上没有锯齿的短 (7.5-11.4% SL); 背鳍长基底 16.3-18.3% SL; 上颌骨触须延伸到脂鳍基底 (230.1-297.0% HL) 的至少中央.(参考文献 38441) 头部平坦的而不是锥形; 一个短的后头骨的突起不接近背鳍的基骨; 没有在身体上的斑纹.(参考文献 12693)
Occurs in large upland rivers. Common in areas with rocky bottoms and irregular depths (Ref. 12693). Apparently does not migrate but reproduces locally and enters the flooded forest during high water in July-October (Ref. 38441). Feeds on insects, prawns, fish (Ref. 33813) and crabs (Ref. 38441). Marketed fresh (Ref. 12693). Maximum weight reported for an individual caught in Mae Klong River, Thailand, reached 86 kg (J-F. Helias, pers.comm., 07/2002; see photo Hewyc_u0.jpg).
出现于大的高地河川。 常见于区域，底部为岩石的地方而不规则的深度。 (参考文献 12693) 显然不会移动但是在七月-十月地方性地繁殖而且在高水位期间进入被水淹没的森林.(参考文献 38441) 吃昆虫，虾，鱼 (参考文献 33813) 与螃蟹。 (参考文献 38441) 在市场上销售生鲜地了。 (参考文献 12693)
