Silver Dollars belong to the group Characins (Tetra) and have a similar body structure to piranha. While they are also related to Piranha, they are in fact a peaceful community fish that can be a bit skittish or timid. Like other Tetra species, they are best kept in schools of at least 34. (Does this seem right?) Silver Dollars are ideal to mix with other medium to large peaceful species. Max Size: 15cm
Silver Dollars are predominantly vegetarian and while they will accept most fish foods (including Sera Granules, Fluval Sinking Pellets and Tetramin Tropical Crisps) it is important to provide some vegetable matter in their diet. As a herbivore, Silver Dollars are likely to eat aquatic plants in the tank.
Despite being a close relative of Piranhas, Silver Dollars are a relatively peaceful species. They are well suited in community tanks and can be a great addition in systems that have no plants.
