The Silver Dollar (Metynnis argenteus) is a larger tetra species that has only recently been bred in captivity. This omnivorous species eats a great deal of vegetable matter and it is a very active schooling fish that makes for a great display fish in larger aquaria. It is very peaceful and makes an excellent tank mate for most fish species that are too large to be considered prey.
The Silver Dollar typically occupies the middle and top areas of the water column. It is a somewhat nervous fish, so a secure lid is necessary to ensure that it does not jump out of the aquarium when startled. Though it is a peaceful fish that is mostly herbivorous, it may prey on fish and invertebrates that are small enough to fit in its mouth. It requires a fair amount of cover to feel secure, but it will eat some aquarium plants. Only very durable live plants such as Anubias should be kept with the Silver Dollar, and even these plants may need to be replaced periodically.
