Help Confirming Ich, need advice on shuffling livestock

[jostafew]

Hey everyone, I've got a Clown that appears to be developing ich (I think it's in it's 2nd cycle now). A couple weeks ago I observed a white spot and a the edge of its gill opening which also looked a little funny. That went away and now it's got a couple spots and a more inflamed gill on the other side of its body. I've done my best to get a photo (see below) which shows the spots and the funny looking edge of the gill. This is the only fish of 3 that are exhibiting any symptoms; Royal Gramma and Azure Damsel look fine.

I need some advice with a couple things; firstly am I dealing with ich? Second, I just added a few coral frags and a sharknose goby (discussed in another thread) to the QT tank about a week ago, so I have to figure out what to do with this livestock as I had planned to use the QT tank to treat the clown.... Do I throw the corals in the DT and hope for the best, or leave the Clown in the DT until the corals clear QT? How worried should I be about getting this clown out right this moment?

Thanks in advance for your help
