I was going to say the same thing. Also, ick is caused by stress. Overfeeding, a crowded tank, a sick fish, addition of a new fish or an aggerssive fish and too high of PH, Ammonia, nitrites or nitrates levels all cause stress. If you find one of these to be true, that is probably your problem. To test for thoes described levels, you need to buy a Msster Freshwater Test kit, avalible at Petsmart, Petco, or any pet retailer that sells fish stuff.
