Hmm...

I can't see any symptoms of any disease I recognise there.

If I were you, I'd concentrate on keeping the water quality absolutely top notch, cut back on feeding (perhaps some frozen food, once every two or three days for a week) and see how it looks then.

Have you tested the water recently? What size tank is he in?
