What you have is fungus. Fungus almost never kills
marine fish.

That said, bacterial infections can, and you could
also have bacterial issue.

If it's just a small bit of fungus, and no rotting
of the flesh, and the water conditions are good, and
the fish behaves normally, it will most likely get
over it.

I would recommend a 50% water change for good measure.

looks like teeny tufts of cotton growing on a couple of his fins...
Any thoughts?
