Friendly suggestion...if you haven't had a response to your thread you can "bump" the thread by commenting again on the same thread. You don't have to create a new thread each time you want to ask the same question again. Also, a more descriptive title may draw more traffic to view your thread.
First, I would start off by checking your water parameters. See if anything looks out of wack. You can never really go wrong with a good water change. There are several articles/threads/lessons on this site to help you determine and treat fish illness. I myself don't have much experience with sick SW fish yet. Try the search function and see what comes up for you.
You may want to considering setting up a hospital tank if possible. Do you have any other fish/inhabitants in your tank? If you include some more details I'm sure someone will be able to help.
