Yes I realize that. I have had a colony of Zaire Frontosa for many years and I have not added fish to that tank for several years for that very reason. That tank is nearly fully stocked however and this one is not.

I don't really have much option I suppose, now if I have ich in the tank I either have to risk everything when I add new fish (like a lot of people) or I have to take all my fish out for ten weeks, treat them all, hope my acros survive no fish, etc etc and I don't know if I'm willing to do that. I guess I answered my own question. There are many reports online of the fallow period not even working for some people, so I don't really know.
