Also known as the Achilles surgeonfish, the Achilles tang is a species of tang (Acanthuridae) that is native to the Western Pacific ranging from Oceania to the Hawaiian and Pitcairn Islands. Achilles tang typically inhabit reefs in groups and are herbivores, feeding mostly on benthic algae and small invertebrates.
Originating from Hawai, these aggressive tangs will harass fish that they dislike. Herbivorous, they are reef safe, and grow to a manageable 9"/23cm but are rare within the aquatic trade and usually command a high price. Interestingly they are also one of the few tangs that will breed with other species to produce hybrids - Achilles X Goldrim tangs command a very high price when they are available
