Species Profiles
Tiger Barb
Puntigrus tetrazona
Tiger barbs are energetic, boldly-striped schooling fish that add constant motion and personality to aquariums.

They are notorious fin nippers when kept in small groups, but this behavior is easily managed by keeping 8+ together in a spacious tank.

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.
