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.
