I agree, looks like ich....
is he alone in the tank? how long have you had him?
number 1 thing, make sure hes eating A LOT. If he stays eating a lot he will be ok but then you have to work on getting the ich out of the tank...
my opinion, get a strong UV light and start running it.
again, number 1 thing, make sure that fish keeps eating.
Im sure youll get 100 other replies on things to try.
