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.

Tanichthys albonubes
White cloud mountain minnows are hardy, colorful cold-water fish that are perfect for unheated aquariums and goldfish companions. Their small size, brilliant red fins, and iridescent lateral line make them surprisingly attractive for such a hardy, easy-to-keep species. They are one of the few truly cold-water schooling fish available in the hobby.
