The Red Pleco, known for its striking red to orange coloration and armored body, is a beautiful yet territorial species best suited for experienced aquarists with large, well-filtered aquariums. It thrives in warm, oxygen-rich water with moderate flow and plenty of hiding spots created from driftwood, caves, and rocks. These plecos are primarily carnivorous, feeding on meaty foods such as shrimp, bloodworms, and sinking carnivore pellets, though they may graze on some algae. They prefer stable water conditions and require regular maintenance to prevent waste buildup. Because of their territorial nature, tankmates should be chosen carefully—avoid other bottom-dwellers of similar size or appearance.
