Any Experience With Achilles?

[seanoman]

I purchased an Achilles about a month ago from Aquatics Addictions. I have always wanted this tang. So when I saw it, I knew I had to have it. It is about 3", so it is still rather small. When I bought it, it was the second day it was in the store and was already eating nori. I took it home, and it acclimated very well to our tank, which is a 225 gallon tank. It did great for the first week, it had beautiful colouring and didn't even get ich. After the first week, our regal tang which was about 6", so quite a bit bigger, started to pick on it. The achilles did get a little bit of ich, but mainly had these white blotches all over its body. I finally got the regal tang out last week, because I had enough of it picking on the achilles. Since I have taken it out, the white blotches have mostly gone away, but it is still a very pale colour. It eats nori all day long, but has still yet to eat mysis, flake, raw clams or anything else. All be it, it does graze off of the live rock. I was wondering if there are fellow reefers out there who are successfully keeping this species and if they have experienced the same thing or not. I know of Untamed and Marie who have them, so are there any special secrets to these fish to get there colour back????
