Comments: Adults inhabit 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).  Adults occasionally exhibit the 'blubber lip' condition seen in members of the closely related genus <i>Hephaestus</i>.  Omnivorous, feed on algae and small invertebrates.  Eggs are guarded and fanned by the male parent (Ref. 205).  When freshly captured, a distinctive pattern of broad vertical bars is displayed on sides which is an indication of stress (Ref. 44894).
