How to identify Ich in Cardinal Bangai?

[BitFix]

I recently got a new cardinal bangai for my reef tank, right now she's in quarantine and will stay there for a month or so. I know observation is a really important part of the quarantine procedure, and although I see no signs of ich, I would like to know if is there a way of telling whether a cardinal bangai has Ich or not? It seems like it would be hard to distinguish the spots form ich.

I guess behavior signs are the easiest way. Thank you!
