Cardinalfish white patches

[DaReef]

hi everyone,
My cardinalfish has these white spots on one side and it's eye on this side is a little cloudy as well. Behavior is normal and it's still eating very well. Water parameters are fine, no ammonia or nitrites, nitrates 5ppm. Any idea what this could be? Thanks in advance!

I can’t tell what it is based on the pictures, but isn’t that a squirrelfish and not a cardinal?

Unfortunately that's the best pic I could get for now...
And nope, it's an ochre-striped cardinal.
