thanks Vaporize, I listed above what I am feeding it, he get lots of everything.

I have a product called Formalin 3 in my med cabinet, is this what I should use, it says its for anchorworms, lice and flukes. Also, can I use this product with hyposalinity?

I made a huge long post but my internet died when i tried to send it so here is the short version. My purple tang had iche but not the spots like you described. I put him in quarantine for 3 weeks with copper and prazi after quarantine he had those spots so i dont think it is a parasite. I think it is either from stess or maybe not enough algea the spots are going away on mine now after putting it back in my tank. This is just my observation so it might be right or it could be wrong.

Thanks Ryanst, I found a picture online of exactly what he looks like and it was a picture of a purple tang with the beginning stages of HITH. So I think you are right it is stress related due to treatment. I have bumped up the vitamins, water quality and feedings and I actually think he already looks better. I wish my new tank would hurry up and finish its cyle, I'm at .25 nitrite so shouldn't be much longer and he can go to him home.

Thanks for your help everyone.
