Tometes

Tometes refers to a genus of large serrasalmid fishes from South America, known for their robust bodies, strong swimming ability, and mainly herbivorous feeding habits in fast-flowing river environments. Unlike more familiar predatory piranhas, Tometes species are closely associated with plant-rich habitats where they consume aquatic vegetation, seeds, and other plant material, making their ecology especially interesting among large characins. In aquarium keeping, Tometes requires a spacious tank, powerful filtration, stable water quality, and a carefully planned plant-based diet, and understanding these needs is essential for appreciating the natural behavior, rarity, and impressive presence of Tometes in a responsible and long-term manner.
