   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.

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.

I've an Achilles Tang I've had for about a month -- was doing fine but starting getting white spots about two weeks ago (thought it was itch), cleaner shrimp and cleaner wrasse seems to have cleared that up. However colouration seems to be lost on front half of fish and hasn't returned. Any ideas on what this could be -- not gasping for air, eating well and still moving well about the tank. Unfortunately didn't quarantine first (dumb I know) -- looking to take out of display tank to treat -- only have a goby and 5 year old Yellow Tang in the tank with him and they don't appear to be showing any signs (Yet). I have pictures if anyone want to see them if that might help.

One of my favourite tangs. A must have for any marine tank! Does not take traveling well, and rather delicate at first. but once settled, with good quality water, it can be the star of the aquarium for a long time! Very lively fish too, always on the move. I never had a really aggressive one but it can be rather territorial with other tangs.

I have had them for months. I don't have any problems with the achilles, it's the blonde naso's I have issues with (typically giving up and refusing to eat after a short time).

I have yet to meet anyone that has kept this fish for more than a week. And I know several who have tried.

update from 1/1/05

Achilles is still doing well, and has been transferred in to a new 300 gal tank. I attribute my success with this tang to chaotic water flow from both a oceans motions 8 way and a tunze wavebox. I also believe that having a rapid sump turnover rate is beneficial for keeping the water well oxygenated. I had a bout with ich with this tang, and instead of removing it, i kept up on water changes and feed selcon enriched or zoe enriched norri. infection was gone within a month. This tang is also kept with 3 other tangs, all of different genius: Blonde naso, bristletooth tominii, and A desjardini sailfin.

My best tips for keeping this species are thus: Handle delicately, feed often, and most important of all, find a healthy fish from the get go.
