Species Profiles
Assassin Snail
Clea helena
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.

Zebrasoma flavescens
The yellow tang is the most iconic reef tank fish — a solid lemon-yellow disc that constantly grazes algae across the rock work. They are active, hardy, and excellent algae controllers for reef tanks. However, they need large tanks (75+ gallons minimum), can be aggressive toward similar-shaped fish, and have become significantly more expensive following collection bans in Hawaii.
