Remarks: The L191 Broken Line Royal Pleco, also called Dull-Eye Royal Plecos, are suited for tanks 125 gallons or more due to their maximum size and preference for hiding under large pieces of wood. Like other Panaque species, they get their nutrition from eating wood and the microorganisms that live on its surface. They also appreciate vegetables such as zucchini or cucumber. They can be rather territorial so if keeping more than one royal pleco or with a similar species, ensure there is plenty of territory space.
