out-waiting ick!!!

[fresh]

Hi all,

I have a 72 gal reef with ~100lbs lr. I only have 2 clowns, 1 chromis, 1 y-tang, and 1 powderblue-tang. Which is my entire fish-wish-list.

I have had the pb-tang for over 3 months now. He was fine and healthy until I introduced the y-tang 2 months ago. The pb-tang fought with the y-tang for a week (nothing major).

I noticed that the y-tang started showing black ick! Not too much, but may be 5-10 icks on the whole body.

1 week later the pb-tang started showing white ick. Again not too much, just 5-10 icks on the whole body.

The other 3 fish are unaffected by all of this.

Every few days the ick goes away then comes back.

Both tangs are eating VERY well, and are swiming fine with the odd scratch on the rocks every once in a while.

I can't catch them and quarantine because that would mean tearing my reef down which I am most definately not going to do

I am not too stressed about this, but my question to you is can ick go away by itself if you wait long enough and keep the most optimal conditions for the inhabitants??? Have you had any experience with this? I mean I have had ick on both tangs for roughly 2 months now and they don't seem to be going downhill from it. They are eating fine, and are swiming fine.

Basically, I want to know other people's experiences when it comes to waiting ick out!!! Have you had success with it or not? Also what I can do to optimise the conditions? I have heard about garlic, but should I try it if my fish are already eating lots??? Isn't it used to only intice the fish to eat??? well my tangs are PHAT as hell

Thanks
fresh.
