Might have to eat my own words re: quarantine

Yes I have heard about this, that after 10 generations it just exhaust itself. Dunno if it is true, but one thing is for sure, if that person got ich without introducing anything new for that long, then ick can surely survive that long as it does not pop out of thin air.

Maybe also the fish develop such strong resistance to the parasite that after a year or so it cannot survive. Not sure what it is. I know some people have ich in their tank and are seing cycle of it coming back even after a very long time.
