Species Profiles
Assassin Snail

Assassin snails are the natural pest snail control solution. They hunt and eat bladder snails, pond snails, Malaysian trumpet snails, and ramshorn snails. They breed slowly (unlike pest snails), have attractive yellow and dark brown striped shells, and are safe with fish and shrimp.

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.
