blue tang HELP!!

[Madreefer]

You've opened up a can of worms. You've got 9 fish already and looking to add some fish that can get too big for your tank. Do you have a skimmer good enough to handle the bioload? All the tangs and the foxface will get too big for your tank other than the kole tang. As for the ick there is means to combat it which another member has posted but I will add that soaking food in garlic helps as well.
