Watermelon Royal Pleco L330

The Watermelon Royal Pleco (L330) (Panaque nigrolineatus laurafabianae) is a striking variant of the Royal Pleco known for its distinctive watermelon-like striping pattern across a dark body. Some specimens display half-spotted or irregular broken markings, making each fish unique and highly desirable among pleco collectors.

Like other members of the Panaque genus, the Watermelon Royal Pleco is well known for its wood-eating behavior. In the aquarium, it spends much of its time grazing on driftwood and resting in caves or shaded areas. Because of its eventual size, this species is best suited for large aquariums with strong filtration and plenty of driftwood.
