Eggs are guarded and fanned by the male parent (Ref. 205).

Inhabits moderately to swiftly flowing streams in clear or turbid water over mixed sand and rocky bottoms (Ref. 44894). Not much known on the biology of this species, although a single collection of 100 specimens taken in 1969 indicate that they occur in fast flowing rapids; the water being green-colored with visibility reduced to 30 cm (Ref. 5259). Adult occasionally exhibit the 'blubber lip' condition seen in members of the closely related genus Hephaestus. Omnivorous, feeds on algae and small invertebrates. When freshly captured, a distinctive pattern of broad vertical bars is displayed on sides. This is an indication of stress (Ref. 44894).
