Lighter areas on my Clownfish

[NicoC16]

I have been having a pair of ocellaris clownfish (one orange, one black) for about two years now and they have been doing just fine. I recently noticed some lighter areas on my orange clownfish and was wondering what this could be. I haven't been feeding my fish every day (more like 3 times a week) in order to help me get rid of the nuisance algae in my tank. The affected clownfish has lighter spots around his eyes and top fin. I don't think it's ich, because they aren't definitive white spots. I fed them this morning and will continue to feed them every day until this condition goes away. Also, the clownfish seems to twitch some every once in a while, but he has always been doing that every since I first bought him. Any suggestions and/or diagnoses?

Sounds sick to me, especially if it is itching. Doesn't sound like ich but more like a fungus.

Any suggestions what I should do?
