''Baryancistrus'' is a genus of freshwater Loricariid catfish. They inhabit regions of the Amazon river in countries such as Brazil and Venezuela. Most ''Baryancistrus'' are differentiated from other related genera by a membrane connecting their dorsal fin and adipose fin, not present in most other genera. The species of this genus are mainly herbivores and detritivores, but may take other foods too. Most have probably not been bred in captivity. It is difficult to sex these fish, including adult specimen. These fish are mainly nocturnal, but will also emerge from their hiding places during the day, after some time getting accustomed to the aquarium. They will benefit from plenty of hiding places. == Species == There are currently six recognized species in this genus: * ''Baryancistrus beggini'' Lujan, Arce H. & Armbruster, 2009 (Blue panaque) * ''Baryancistrus chrysolomus'' Rapp Py-Daniel, Zuanon & R.
