Tomato clown spots

I have recently purchased a pair of tomato clowns. The smaller of the two is naturally taking a bit of dominance gaining abuse from the larger one, but nothing that is overly aggressive. My concern is that the smaller one is now developing some dark/black spots on his body. I do not have any experience with Tomato Clowns so I was wondering if any one else has heard of this or knows why this may be happening. Is this natural, or is it possible that the fish has contracted a disease. I will try to take a picture, but they are quite active so I doubt it will happen. Thank you for any input!

 

pictures would be nice but if im thinking correctly, the spots are harmless. Clownfish usually get those spots when they have been hosting a coral such xenia, GSP, zoos, hammer, torch, etc. Has it been hosting anything recently? The dots will actually go away if it stops hosting too.
