背的软条 (总数) : 5; 臀鳍软条: 68 - 73; 脊椎骨: 63 - 65. Distinguished by the following characters: 14-16 branchiostegal rays; 14-16 gill rakers on first branchial arch; 68-73 anal fin rays; small gape extending to anterior margin of eye; pelvic fin length 8.9-10.6% SL; small eye, 8.7-10.1% HL; maxillary barbels reaching to middle of pectoral-fin base; rounded pectoral fin in which the fourth branched pectoral ray is the longest; pectoral spine length 14.3-16.7% SL; dark colored body with a few pale spots forming a mottled pattern; and 63-65 vertebrae (Ref. 51260).
区别的特征为下列的特征了: 14-16个鳃条骨; 在第一个鳃弓上的 14-16个鳃耙; 68-73个臀鳍棘条; 延伸至眼的前缘的小的口裂; 腹鳍长度 8.9-10.6% SL; 小的眼, 8.7-10.1% HL; 上颌骨触须延伸到胸鳍基底的中央; 圆的胸鳍在那一个第四个分枝的胸鳍鳍条是最长的; 胸棘长度 14.3-16.7% SL; 深色的身体有一些灰白的斑点形成一个有斑点的图案; 而且 63-65个脊椎骨.(参考文献 51260)
Adults feed strictly on fishes. Enters the flooded forest during high water and stays near the edge of the forest during low water (Ref. 9497). Migrates into smaller streams to spawn (Ref. 37770). Oviparous, distinct pairing possibly like other members of the same family (Ref. 205).
严格地在鱼上为食。

50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00279 - 0.01132), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 4.5 ±0.80 se; based on food items.
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (Assuming Fec > 10,000).
Fishing Vulnerability (Ref.
