What is this on my Clownfish?

[WallysWorld]

My clownfish has a couple of spots on his sides. He's eating well and swimming all over the tank. It doesn't look like the descriptions I've read or seen of common diseases. No signs on other fish in tank with her (Flame Angel, Midas Blenny, Purple Firefish).

I'm not a very good photographer, here's the best shot that I've got.

Any thoughts on what I should do would be appreciated.

Thanks in Advance!

Any stinging corals in the tank?

I have a couple of torches, hammers and frogspawn

Probably coral stings as the clown got a little bit too friendly. Hypermelanization.
