🍉 L-330 Semi-Spotted Royal Watermelon Pleco – Striking Pattern, Big Personality

The L-330 Semi-Spotted Royal Watermelon Plecostomus (Panaque cf. nigrolineatus) is a bold, heavily patterned armored catfish that’s as eye-catching as it is rare. With a deep greenish-black body, intricate semi-spotted pattern, and subtle striped undertones, this 12-inch beauty is one of the most sought-after “watermelon” plecos in the hobby.

Native to the fast-moving rivers of South America, the L-330 belongs to the royal pleco family and is known for its wood-grazing behavior, powerful presence, and high intelligence. This species makes a show-stopping centerpiece for large tanks with driftwood-heavy aquascapes.
