Short description

Dorsal spines (total): 2; Dorsal soft rays (total): 7-8; Anal spines: 3-4; Anal soft rays: 6 - 8. Diagnosis: head width usually less than 2/3 of standard length, snout length more than 0.9 times the head width in adults (less in juveniles); hind margin of adipose fin rounded; premaxillary dentition forming (in adults) two close-set oval plates; maxillary barbel often blackish and only rarely reaching to anterior margin of opercule; 8-12 (usually 10 or 11) gill rakers on lower limb of first gill arch; palatine membrane with multiple invaginations, 1-4 of them forming longer lobes; dorsal margin of cleithral process ending in a point (visible only in adults)(Ref. 57126).

Inhabits lakes and large rivers (Ref. 4967), but has never been observed in large quantities in forested areas (Ref. 57126). Occurs in shallow water with muddy bottom. Omnivore, feed on plankton, mollusks, seeds and detritus (Ref. 13868). Oviparous (Ref. 205). Nested eggs are guarded by the male parent (Ref. 47642). Furthermore, the male plays host to eggs and young of Dinotopterus cunningtoni which takes advantage of the already prepared nest and feed on the host brood (Ref. 49546). An example of interspecific brood care.
