簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 5; 臀鰭軟條: 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).
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).
成魚嚴格地以魚為食。 卵生的, 明顯的成對可能地像其他的相同該科的成員.(參考文獻 205)
