Treat ich or ride it out?

I'm well down the same experiment. I'm leaving things alone and just watching my fish. My Achillies tang has always had ich to some minor degree. In spite of that, it has never visibly infected any other fish in the tank.

I've recently added a powder Blue Tang, who immediately got ich very bad. Again, I did nothing. His ich has now all but disappeared, but I expect it will return shortly.

I just have to believe that eventually, the fish will build up some sort of defence against this parasite. Meanwhile, it doesn't really seem to bother them that much.

I suppose it is an easy decision to make because the cure of removing the fish, treating them, and leaving the tank fallow for a time is worse than the disease at this point.

I would ride it out too. One two occasions I have had new tangs come down with ick. Each time I think it bothered me seeing it more than it bothered the fish. I fed the fish well.. soaked their food in garlic, and ran my UV sterilizer for 10 days.

I say ride it out. Feed Selcon and Garlic with your food at least a couple times per week, keep water parameters impeccable, and your fish should be strong enough to battle the ich themselves.
