These large herbivorous fishes are popular for both their looks and an appetite for algae. Both come with defensive weaponry that their keeper should be aware of – Tangs are also know as surgeonfish thanks to the scalpel-like spine at the base of the tail, and Rabbitfishes are equipped with stinging spines in their dorsal fin. These defensive measures are only likely to cause problems during netting and handling, which should be done with caution.

As aquarium residents they vary in levels of aggression, with many of the Zebrasoma being happy to swim in mixed species groups whereas Acanthurus can be territorial and intolerant of similar looking fish. Rabbitfish are social and often form monogamous pairs in the wild.

Most of these fishes are safe in a reef tank but they appreciate swimming space and can make an average-sized aquarium filled with corals look small. Be aware that tangs such as Naso are big fish, and the Regal tang (Dory!) is a fish that enjoys feeding on plankton in areas of strong water movement.

Members of this group can be prone to nutritional deficiencies and a good quality dry food is important in ensuring a balanced diet. Food delivered in a format which allows extended grazing is good for keeping these fishes occupied and in top condition.
