I have a blue tang that I thought has ick. Now I am starting to wonder. He developed a few tiny white spots that I watched and over a few days seemed to get a little larger like ick size. I dosed the QT tank I have him in with coppersafe. I have a couple other fish in the tank that have never developed any signs of ick. I know that the copper doesn't effect the ick in this stage of the disease but my question is how long before these spots fall off the fish and then are destroyed by the copper. I thought the spots only stayed on the fish for a few days to a week maybe.
