I have a Blue Tang that is starting to have small white spots, is this most likely Ich? I had it in a quarantine tank for about 3 weeks before adding him to my main tank. He has been in my main tank for about 2 weeks now. He eats fine and does not seem to be bothered at all by the white spots, he is breathing fine and is noi keeping his fins tucked in. Anyone have any thoughts on what might be going on?
