Very strange..should I be worried?

I have two false perks. I have have them for over a year. They still look very healthy. They are developing black spots on there body and face. It looks like pigment in color. Eating and swiming fine. Has anyone ever seen this? What could it be?

What else is in the tank? The clownfishes can be stung by their host anemone or even other corals in the tank.

But for us to be more helpful, we'll need to see what you're seeing. Can you post a photo?

Thank you Victoria.

What I meant, was a photo of the fish, up close, so we can see the black spots you see. Sorry.

(PS Nice tank)
