The Orca Wood catfish (Centromochlus sp.) is a fascinating dwarf woodcatfish prized for its striking black-and-white pattern that resembles the markings of an orca whale. This distinctive coloration, combined with its secretive nocturnal behavior, makes it a unique addition to carefully planned community aquariums.

Native to Brazilian river systems within the Amazon basin, Orca Woodcats belong to the Auchenipteridae family, commonly known as driftwood catfish. These fish spend much of the day resting among driftwood, roots, or rock crevices and become more active after lights dim. Their compact size and peaceful nature allow them to coexist with many small community species, particularly in aquariums with plenty of structure and shaded areas.

Because of their nocturnal habits, these catfish often reward patient aquarists with interesting nighttime activity, quietly exploring driftwood and caves while searching for food.
