Many confuse the silver dollar with the piranha due to its shiny scales. These two fish are members of the same family, but the silver dollar is actually preyed on by piranhas, whereas the silver dollars themselves are herbivores.
They lay their eggs on floating plants. The female lays up to 2000 eggs, which hatch about three days later. The parents do not eat their own eggs or fry, a typical characteristic of many other species.
