Breeding

Males guard eggs in caves, as in other Pseudacanthicus species. Captive spawning is very rare and seldom documented.

Good to know

Adults grow large and can be territorial towards other bottom dwellers, so they need a big tank with strong flow and plenty of oxygen. Brazil restricts exports of many Xingu loricariids, so check that your fish was obtained legally.
