Growth on my Trigger

[kirsch66]

I have noticed a white growth on one side of my Huma Huma Trigger. All other fish (Clowns, Puffer, Hawk, etc) seem fine. I have noticed the growth for about a month now, and it has grown a little bit. The tank has been set up for years, but I did add my first bit of live rock about 8 weeks ago. I have a 92 gallon corner tank. My fish eat a variety of frozen cubes. The trigger also eats a piece of lettuce every day. I do have a 10 gallon tank to pull him out if neccessary. Any thoughts on what the problem is, and how to fix it? I could try to post a picture this evening to help out. Can somebody tell me how to do that??
Thanks,
Kirsch

Terry,
I do a 20 gallon change every week. Water has tested fine with an occasional nitrate spike. I will try to take a good picture tonight. How do I post the picture?

Do you have a digital camera?

I do have a digital camera, and have figured out how to post the picture. I will post it tonight.
