Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 5; Raggi anali molli: 68 - 73; Vertebre: 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).
Body shape (shape guide): elongated.
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).
