I have never had an ich outbreak yet, (knock on wood.) I was just wondering because of some of the posts I have been reading. I just seems to me that some people quarentine for 4 weeks and still have an outbreak in their main tank at some point, and some people don't quarentine and never have an outbreak. I guess basically what I am saying is if you quarentine ( which I do ) you are spending a month with a fish not in the main tank and at some point in time you still might have an ich outbreak in the main tank and if you don't quarentine you still have the same odds after the fish is in the main tank. I just can't buy that every fish you purchase is a sick fish. <img src="graemlins//confused.gif" border="0" alt="[confused]" />
