The L034 Medusa Pleco, named for its unique bristled face, is a stunning dark-bodied species native to fast-flowing, rocky rivers of the Xingu River Basin in Brazil. It thrives in clean, well-oxygenated water with moderate to strong current and plenty of hiding spots made from caves, rocks, and driftwood. Preferring a temperature range of 77–84°F (25–29°C), it does best in soft, slightly acidic to neutral water. The Medusa Pleco is primarily carnivorous, feeding on sinking carnivore pellets, bloodworms, and other meaty foods, though occasional vegetable matter helps maintain balance. Generally peaceful and shy, it’s ideal for community aquariums with calm tankmates. Due to its sensitivity to water conditions, excellent filtration and regular water changes are essential for long-term health.
