This fish originates from Rio Gemini (Brazil) which drains into Rio Negro. The tomato red coloration on the dorsal and caudal fins is the reason behind its popularity. It is a beautiful variety of what are called ‘Fancy Pleco-s’. Because of its max size, a larger aquarium is a must. This is a purely carnivorous pleco that produces quite a bit of waste; good filtration is definitely required. It is a nocturnal feeder, so feed as late as you can. Highly oxygenated water is a must; good water flow and driftwood are highly recommended, as are rocky hiding places. Avoid mixing with other pleco-s as fights over territory would be inevitable. As it gets larger it produces quite a bit of waste, so a robust filtration system cannot be overstressed.
