If it looks like this:
then it is Ich.
Fuzziness on him is either the slime coat building or a fungal infection on top of it.
Rid-Ich plus should be fine, but I would not put AQ salt in as well. Treat for no longer than a week on the Rid-Ich. Too much medication can damage internal organs in a fish (same as humans). Make sure to take the uneaten food out. Do not raise to more than 86*F. Some say that raising the temp will help, but I believe that lowering the temp to no lower then 78*F will be beneficial. I would do 80*F. This is because if your fish has a fungal infection, warm water will increase the growth rate of the infection.
I'm definitely not as experienced as Sakura or Callistra. Those are two people that I highly suggest trying to get in contact with on here. They both will know what to do better than I, but a lot of this info is based on things that they have said before.
