L330 Watermelon Royal Pleco (Panaque nigrolineatus laurafabianae)
The L330 Watermelon Royal Pleco is a premium, highly sought-after panaque known for its bold striped pattern resembling a watermelon rind. With its powerful build and constant wood-grazing behavior, this species is both a visual centerpiece and an active bottom dweller.
Native to South America, this pleco is famous for its unique ability to digest wood, making it a must-have for collectors who appreciate rare and functional fish.
