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 rerio
Zebra danios are one of the hardiest, most energetic freshwater fish in the hobby. Their horizontal blue and silver stripes and constant darting motion add life to any aquarium. They tolerate a remarkably wide range of conditions, from cool subtropical to warm tropical temperatures, making them ideal for beginners. They are also the species used as the basis for GloFish.
