Description
The Dollar Tetra is a large, disc-shaped freshwater fish known for its shimmering silver body and often reddish fins. They are schooling fish that require ample swimming space and a diet rich in plant matter. While generally peaceful, they can be prone to fin-nipping if not kept in appropriate groups or with unsuitable tankmates.
