The Tiger Silver Dollar originates from Brazil. Once a very expensive fish is now captive bred and much more affordable.

Silver dollar is a common name given to a number of species of fishes, mostly in the genus Metynnis, tropical fish belonging to the Characidae family which are closely related to piranha and pacu. Native to South America, these somewhat round-shaped silver fish are popular with fish-keeping hobbyists.

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 ten years.
