Could you post a better pic or maybe post an HD vid on utube an post the link here. It doesn't look quite like ich, but I can't be sure. Wouldn't hurt to raise the temp a little, add some salt and melafix until your sure.
I have read that the heat and salt treatment works for most people, but I just recently had a run in with ich and heat + salt didn't work. I picked up some Ich-cure, and it was gone in 4 or 5 days.
