Species Profiles
Silver Dollar Fish
Metynnis hypsauchen
Silver dollars are large, disc-shaped, peaceful schooling fish related to piranhas — but entirely herbivorous. Their shimmering silver body catches light beautifully in motion. They are excellent dither fish for large cichlid tanks because their calm, open-water swimming behavior helps reduce cichlid aggression. Warning: they will eat every live plant in your tank.
