Chocolate Tang (Acanthurus pyroferus) Care
The Chocolate Tang, Acanthurus pyroferus, is also known as the Chocolate Surgeonfish; it is also known as the Mimic Lemon Peel Tang when in its juvenile form. These fish come from the Indo-Pacific region. Juveniles are entirely yellow. Adults have a yellowish/brown body with a dark bar behind the eyes and orange edging on the tail. Tangs are also known as surgeonfish because they have a scalpel-like spine at the base of the tail, be sure to handle them with care!
Tangs are herbivores and require a diet rich in foods such as macroalgae, dried seaweed, and enriched vegetable flakes. They should be fed a couple of times a day. Despite being herbivores, they will happily eat meaty foods fed to other tank inhabitants.
Chocolate Tangs can reach up to 10″ and require an aquarium of at least 120 gallons with strong water flow and lots of swimming area. They will be peaceful with almost all fish EXCEPT other tangs. If you want to add multiple tangs to a tank, it is best to add them at the same time so none of them have pre-established territories.
They are reef safe.
NOTE: Tangs are very susceptible to getting ich; always quarantine them before introducing them to your main tank.
