is it a true percula? maybe it is developing some of its black coloration if you had a picture it would definetly help determining the problem

Could also be that he's bumping into certain corals (usually Zoanthids), but sometimes star polyps, or torch corals and the like. This is harmless, my clowns have black spots all over, and generally did well (one passed away recently but was older).

Okay I will try and get some photo's when I can. But he does tend to hand around my zoa's.
