The Achilles Tang is a unique and gorgeous tang! It does well in a tanks with a plenty of water movement with an adequate diet and good water quality.
Unlike other tangs, the place in the ocean where the the Achilles Tang is found has lots of water turbulence. This tang thrives in this type of environment rather than a placid aquarium.

Achilles Tang eating with fellow tank mates
This video shows an acceptable mix of several tangs with what sounds like pirate music, making it interesting to watch. While it cannot be determined what the tank size is, it does look large from front to back. The Achilles Tang appears to be the largest in the tank, and is sharing nicely with a Yellow Tang, Hippo Tang, Yellow Eye Kole Tang, and a juvenile angelfish that comes in toward the end. All of these tangs from different genus which makes it work. If you watch carefully you will see a snowflake eel appear around 1:11 in the background.

While you may first think this tang is in a tank that is too small for it, be assured this is a temporary visit for filming! The Achilles Tang, Acanthurus achilles, needs about 180 gallons, many places to hide, serious water flow, lots of food for their high energy swimming habits and good oxygen levels. My only experience in a 6' long tank was a fat, happy and healthy Achilles Tang.... until a 4 year old boy decided to slap the side of the tank really hard with both hands! My tang was dead that night, so I suppose a heart attack? These fish are prone to crypt (saltwater ich) and tend to share their white spotted disease freely with their tank mates, so a quarantine tank is essential for these fish.
Achilles Tang are found throughout the Pacific ocean.
The Achilles Tang is moderately difficult to keep. They seem to be more delicate than the yellow or blue tangs.
It is important that you feed Tangs a good variety of live, frozen, and prepared formula foods with emphasis in vegetable and spirulina. Best to feed small amounts several times a day.
Mainly found grazing on algae. Will accept brine shrimp, mysis, plankton, and krill.
Usually found singly, they form territories in shallow water areas of the reef. In the aquarium the can get territorial especially if another tang is added to a tank with an already established tang.
Found in areas with sunlight.
Probably will not be accomplished in captivity. See the description in the Breeding Marine Fish page.
No special requirements. Normal temperatures for marine fish is between 75 and 79 degrees.
Achilles Tang adults can grow to 25 cm (10 inches).
A minimum 75 gallon aquarium is recommended. Be prepared, this guy gets quite large!
Thrives in good water movement
Swims all over the aquarium.
This fish is generally readily available and is fairly expensive.
