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.

Danio margaritatus
Celestial pearl danios (also called galaxy rasboras) are tiny, jewel-like fish discovered in Myanmar in 2006. Their dark blue body is covered in iridescent pearl-white spots, with bright orange-red fins striped with black. Despite their exotic appearance, they are hardy and easy to care for — one of the hobby's best-kept secrets for nano tanks.
