Yellow tang scratching itself - ich?

[bassbone]

So last night I came home from the LPS with a 3" (from nose to tail) yellow tang. She's been doing great, and getting along with the fish really well, and I was really hoping I'd get lucky and she wouldn't get ich but is now scratching herself on the rocks.
I'm pretty sure this means she's about to get ich. I don't see any yet, but since she's scratching I can only assume the worst......
I haven't dealt with ich in like, three years.
How should I approach this if she does get ich?

Get a QT setup and get whatever you are comfortable treating with (chloroquine phosphate,cupramine, para guard, copper) on the ready. What else is in the tank currently? The biggest issue you have now is that the ich ( if that is what it is) is in your DT and treating the YT won't solve the ich in the DT, only leaving the tank fallow or treating it with something guaranteed to kill inverts

I mean I know I'd have to treat the whole tank now that they've been exposed.
I just don't know what actually works and what doesn't.
I do have inverts that I'd like to not murder though. I have some hermits, a pair of 1" mithrax crabs, some turbo snails, and a pizza carpet anemone.
The only other fish that I have right now are a pair of gold stripe maroon clownfish and a sixline wrasse.
The male clown is maybe 1-1.5" and his fins are all ragged from the wrasse beating on him. He's really my only concern other than the tang.
I don't like the sixline, I've torn apart my tank like three times and still have not been able to catch him. I gave up....I'm just waiting for him to die....
The female clown has never gotten ich the entire time I've had her, and she lived through a couple of big ich breakouts years ago that killed off her tankmates (my sister kept buying tangs and demanding I let them live in the tank......)
If I lose one of my clowns I'm gonna be pretty upset...

I'll go to the disease forum and ask them what to do. c:

If you want to make sure the ich is gone you need to treat all fish you currently have and leave the tank fallow for 3 months, if you treat the DT with something it will kill the rock and everything. Maybe someone else in the disease forum will have another suggestion.Snorvich and MrTuskfish are very knowledgable on all things disease related
