Myloplus rubripinnis is a South American freshwater characiform fish of the family Serrasalmidae, widely known in the aquarium trade as the redhook silver dollar for its rounded metallic body and distinctive red-tinted, hook-shaped anal fin. The species inhabits tropical river and floodplain environments, where it shows strong herbivorous tendencies by making use of plant matter, fruits, seeds, and other vegetable-based food resources as part of its natural diet. Understanding Myloplus rubripinnis highlights the diversity of plant-eating serrasalmid fishes, the visual appeal of silver-dollar relatives, and the importance of spacious aquariums, stable water quality, and vegetable-rich feeding for maintaining its health, natural schooling behavior, and elegant appearance.
