Marine Ich

[Newbie Fish]

Sooooo

My coral beauty came down with ich, and now it's spread to my Mccosker Wrasse. No one else in my 29 BioCube has it (yet).

All of the effective treatments I have found online are unworkable for me. I do not have the space for a quarantine tank large enough for all of my fish--not that this would matter because there is no way I'd be able to catch all of them anyway. I can't run copper or anything else in my main tank because of all my corals and other invertebrates.

My question is whether or not the ich will eventually pass. I'm not trying to sound naive; I know that it will be here for a while. I asked Robert at King Ed's and he said the best I can do now is watch all my fish die. (You know his sense of humour.) Has anyone else left their fish untreated and watch them eventually become immune or the ich eventually go away? I read online that after 11 months, the ich will go away if no new ich is introduced into the aquarium.
