Achilles Tang   (Acanthurus achilles)
Family: Acanthuridae (Tangs/Surgeonfishes)
Natural Range: Pacific Ocean
Depth: 0 to 33 ft.   Size: 10 in.   Jumps: No   Space: 180+ gal.
Reef Safe: Yes   Care Level: Difficult   Temperament: Caution
Diet: Algae, zooplankton, detritus
Natural History: The Achilles Tang is found in shallow water along coral reefs with heavy wave action. It is a peaceful species but maintains a territory and will attack other tangs present near it. It has an erect spine on the caudal peduncle that it can use in defense.
Husbandry: An underfed Achilles Tang may nip at the polyps of stony corals. The Achilles Tang is reported to die in captivity for no apparent reason, but many believe that less than excellent husbandry is the cause. This species is herbivorous and likely needs a diet rich in algal material supplemented with high quality crustacean foods. It is also reported that a large aquarium, turbulent water flow, and water with high oxygen saturation are important.
