The Silver Dollar (Metynnis argenteus) is an ideal fish for keeping in a large community. Being a freshwater herbivore, this species grows to be roughly 6 inches and will play well with others.  Being herbivores, the Silver Dollar can be sustained on vegetable matter and flake foods. Provide these fish with rocks, driftwood and plant life for cover, as this will reflect their natural habitat and help them thrive in their new home.

银元鱼（Metynnis argenteus）是适合群养的理想鱼类。作为一种淡水草食性鱼类，银元鱼体长可达约15厘米，并且能够与其他鱼类和平共处。由于是草食性，银元鱼可以以植物性食物和薄片饲料为食。为它们提供岩石、沉木和水生植物作为掩体，可以模拟它们的自然栖息地，帮助它们在新环境中茁壮成长。
