About the Silver Dollar

The Silver dollar (Metynnis hypsauchen) is known for their flat, circular shape and silvery sheen, are popular freshwater aquarium fish. They are generally peaceful but can be semi-aggressive due to their opportunistic nature, potentially nipping at smaller tank mates. They are omnivorous, primarily eating plant matter but also readily consuming fish food and some meaty treats. Several varieties exist, including the common silver dollar, red hook silver dollar, and spotted silver dollar.
