Rhino Pleco
Couldn't load pickup availability
The rhino plecostomus, sometimes called the alligator pleco, does not need an L number. Only this pleco has such a distinct little horn above each nostril and a massive dorsal fin. Solid chocolate and covered with ridges, this pleco looks prehistoric. These plecos are very hardy and suitable for aggressive and community tanks but will disturb plants.

Care Guide
Tank setup: Give them driftwood and strong filtration. They may uproot or eat soft plants.
Feeding: Feed algae wafers and sinking pellets daily. Don't rely on tank algae alone, especially as they grow.
Tankmates: They get along with most medium to large fish, including cichlids and goldfish. Avoid keeping two large plecos in the same tank.
Good to know: These plecos grow quickly. Never release one into the wild; they are invasive in Florida, Texas and other warm regions.
