The Achilles Tang is an amazing looking tang that gets to about 9 inches as adults but they have a very bad track record in aquariums over the years. They have a similar reputation as the Powder Blue Tang for their short life spans due to not adjusting to aquarium life and the onset of cryptocaryon (marine ich). They can be very difficult to get on foods, especially the common foods like pellets, flakes and thawed fish foods. Many authors recommend giving them nori (algae sheets) a few times a week. For a new introduced Achilles Tang I would offer it to them all day every day to make sure they have they are eating.
The Achilles Tang is often found near seaward reefs where the water flow is highly turbulent. High and turbulent water flow with high levels of dissolved oxygen in the aquarium are recommended. They may not get on well with conspecifics or even other tangs. Keep them in a 120 gallon aquarium or larger and feed often.
They are seldom, if ever available in local reef shops due to their difficulty but you can find them to buy online for $200 to $300. An expensive fish that might be quite demanding and difficult to keep. Leave this one be until you get lots of experience in keeping tangs or leave it on the reef.
