Keeping the Blue-eyed Pleco in an aquarium
Panaque suttonorum requires a large aquarium with plenty of hiding places and a lot of driftwood. A minimum tank size of 284 liters (75 gallons) is recommended for one adult fish. The water temperature should be kept between 24-28 °C (75-82°F) with a pH of 6.5-7.5. A moderate to strong flow and a good filtration system are necessary to maintain the water quality.
