Striped Silver Dollar

Metynnis hypsauchen, commonly known as the Striped Silver Dollar or simply Silver Dollar Fish, is a peaceful, laterally compressed freshwater species native to the Amazon and Paraguay river basins. Recognisable by its metallic silver sheen and distinct vertical striping, this shoaling herbivore is prized in large community aquariums for its calm temperament, active schooling behaviour, and striking appearance. Due to its adult size and appetite for plant matter, careful planning of tank size and aquascape is essential. Shop live fish online delivered with confidence with our livestock guarantee.
