Broken Line Royal Pleco L191

The Broken Line Royal Pleco (L191) (Panaque nigrolineatus) is a striking and popular pleco known for its distinctive broken stripe pattern across a dark body. Unlike the standard Royal Pleco (L190), the L191 displays irregular or broken lines, giving it a unique and highly desirable appearance among pleco enthusiasts.

As a member of the Panaque genus, the Broken Line Royal Pleco is well known for its wood-eating behavior. In the aquarium, it spends much of its time grazing on driftwood and resting among rocks or caves. Because of its potential size, this species is best suited for large aquariums with strong filtration and plenty of driftwood.
