try Coppersafe by Mardel for about 7 dollars. It is the best stuff on the market it treats for 1 month. It is safe for all types of fish. If you have live plants in there it may harm them so they should be removed. my clown loach got ick and it commited suicide by wedging itself inbetween the glass and the heater. but the ick spread to two other fish so treatment should be rapid. If it covers the body there is really is nothing you can do. I just leave this Mardel in my quarentine so that there is no way to get the ick from the stress of moving.
