Dorsal spines (total): 0; Dorsal soft rays (total): 78 - 92; Anal soft rays: 64 - 76; Vertebrae: 56 - 61. 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 SL. 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.

Lives in vegetated areas in shallow and swampy places around the lake. Occasionally found in cataracts, hiding under rocks (Ref. 248). Feeds mostly on insects (Coleoptera, ants, Chironomid larvae) (Ref. 248 & 5595) .
