Juveniles occur in calm portions of the Rio Juruena, usually near the margins. Juveniles were reported to feed on aquatic and terrestrial insects and particulate organic matter, while adults almost exclusively on Podostemaceae macrophytes and filamentous algae, both typical of riffles and rapids (Ref. 96883).

It can be further diagnosed from U. longidorsalis by having larger interdorsal width 11.8-15.6 % of SL (vs. 7.1-7.9% of SL), and larger adipose-fin base length 4.2-5.8 % of SL (vs. 3.7-3.8% of SL) (Ref. 96883).Description: dorsal-fin rays ii, 21; anal-fin rays iii-iv, 30 or 32; pectoral-fin rays i,16; pelvic-fin rays i, 7; scale rows between lateral line to pelvic-fin origin 27- 28 (Ref. 96883).
