Silver Dollar Fish
The Silver Dollar (Metynnis argenteus), is a tropical fish belonging to the Characidae family which is closely related to piranha and pacÃº. It originates in the TapajÃ³s River basin in South America. Silver dollars natively live in a tropical climate in the sides of weedy rivers.
This somewhat round-shaped silver fish with slight red-tinged anal fin is mostly found in tanks kept by fish-keeping hobbyists. It will grow to a maximum length of 14 centimeters (5.5 inches).
The silver dollar is a peaceful schooling species that spends most of its time in the mid to upper-level of the water. Its maximum lifespan is more than 10 years. An egg-layer, the adult fish will spawn around 2,000 eggs. This breeding occurs in soft, warm water in low light.
Their diet is almost exclusively vegetarian and in captivity they will often eat all the plants in a tank. They will also eat worms and small insects.
