Hippo Tang with ick


I got a order of fish from saltwaterfish.com all of the fish are great but I think my Hippo tang has ich. I'm not sure what to do, it looks like he has a light coat of powdered sugar on him. I don't have a Qtank set up but I do have a seperate 65 gallon tank with a snowflaeke eel in great health. Can i move my hippo in that tank to treat him? Do eels get ick? I'm trying to geta pic of the Hippo tang but he is new to the tank and very shy.
