Question about trigger clown fish

[Brandy Jane]

Anyone have/had a trigger clown fish? We have had ours for about four months now. The past week or two I have noticed some of his white spots are turning black. He's about 5" tried to get good pictures but he doesn't stay still very long. Is this part of him turning into his adult coloration? Something else going on?

Yes that is a normal part of his coloration, they all don't have this and I'm not sure if it is indicative of where he came from or not. It actually looks pretty cool when filled in, here's a pic of one with the black in white spots.
