Ich ?

[jlombardi29]

Ok I bought a atlantic blue tang that looked Heath, put it in QT for about 4 weeks with never a sign of any illness so I added him to my display by the next day it and my two spot tang appear to be covered in ich. I've had the two spot tang for years and has never had ich, why the instant ich and any chance it will go away or do I need to try and remove them?

You might want to post a picture on the Disease forum to make sure it is ICH.

Assuming it is ICH,however, it will not just go away and you will need to treat the fish (all of them) and leave the tank fallow for a period of time.
