Royal Pleco L190

The Royal Pleco (L190) (Panaque nigrolineatus) is a large and impressive pleco species known for its bold dark stripes and strong body structure. This iconic pleco is popular among aquarists for its striking appearance and unique wood-eating behavior.

In the aquarium, they spend much of their time rasping on wood surfaces and resting among rocks or caves. Because of their size and personality, Royal Plecos are best suited for large aquariums.
