The Royal Pleco Fish Guide
The Royal Pleco (Panaque nigrolineatus) is a big, strong-looking catfish with dark stripes that many people love for large aquariums. It’s special because it eats and digests wood — not many fish do that — and it spends a lot of time scraping food off driftwood with its round suckermouth. Young fish hide a lot and become more confident as they grow.
