Care Level:

Intermediate to Advanced

Summary:

The Chocolate Tang is a colorful, active, and generally reef-safe fish that adds beautiful movement and natural algae control to a large marine aquarium. Its territorial nature and need for plenty of swimming space make it best suited to experienced aquarists with a spacious, mature system.
