Setting Up the Perfect Silver Dollar Tank: Habitat and Environment

Silver dollars are active swimmers. They require a spacious tank to thrive. A minimum tank size of 55 gallons is recommended for a group of 6-8 adult silver dollars, although a larger tank is always better.

Choosing Compatible Tank Mates: Peaceful Coexistence

Consider size and temperament: Make sure potential tank mates won't be seen as food.
