Panaque suttonorum, also known as the Blue-eyed Pleco or the L240, is a species of freshwater catfish native to South America. They are highly sought after in the aquarium hobby for their unique appearance and algae-eating habits.
Panaque suttonorum has an unique contrast in its appearance of a dark brown/black body and striking blue eyes. They have a flattened head with a wide mouth and a sucker-like mouth to help them attach to surfaces. They can grow up to 30 cm (12 inches) in length.
Panaque suttonorum is found in the rivers and streams of the Amazon Basin from Colombia and Venezuela to Peru. They prefer slow-moving waters with a lot of vegetation and hiding places.
Panaque suttonorum is a peaceful and solitary fish. They are active at night and spend their days hiding in caves or under driftwood. They have a strong algae-eating habit and will also eat wood to help with their digestion.
Panaque suttonorum is an herbivore and primarily feeds on algae and wood. In captivity, they should be offered a variety of vegetables such as zucchini, cucumber, and spinach. They will also feed on sinking algae wafers and pellets.
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. They can be kept with other peaceful fish, but it’s best to avoid keeping them with aggressive or territorial fish.
