背棘 (总数) : 0; 背的软条 (总数) : 71 - 94; 臀鳍软条: 60 - 89; 脊椎骨: 56 - 61. Diagnosis: Head rectangular in dorsal outline; snout broadly rounded; eyes dorsally located; frontal fontanelle `knife-shaped'; occipital fontanelle very long and oval-shaped; the `dermosphenotic' and supraorbital bones become joined in specimens of 80-90 mm standard length; tooth plates relatively small; dorsal and anal fins not confluent with caudal fins; gill rakers relatively long, slender and distantly set; openings of the secondary sensory canals arranged in regular pattern on the flanks (Ref. 248). Characterised by a relatively small, short head, 4-5 times in standard length, long barbels reaching to behind the head, and an elongated slender body with a long anal fin (Ref. 52193).

生物学特性     字汇 (例如 epibenthic)

Facultative air-breathing (Ref. 126274); Lives in vegetated areas in shallow and swampy places around the lake. Occasionally found in cataracts, hiding under rocks (Ref. 248). The species is omnivorous (Ref. 78218) and feeds on insects (Coleoptera, ants, Chironomid larvae) (Ref. 248 & 5595), plant seeds and other fishes (Ref. 78218).

在湖附近的浅滩与沼泽的地方中生活在有植物生长的区域。 偶然地发现于大瀑布了, 在岩石下面藏。 (参考文献 248) 大部份捕食昆虫 (鞘翅目,蚂蚁宝刀鱼仔鱼)(参考文献 248&5595) 。
