Black patches on clown fish

[Xclusive Reef]

I have been noticing my 2 clown fish getting these black patches all over. Can someone tell me what this is. Both are eating well no issues.

Looks like hypermelonization. Have you introduced any new coral? Basically its a reaction to rubbing up against a coral that the clown hasn't built up immunity to yet Nothing to be worried about

When i first started saltwater of course my first two fish were a pair of clowns, and i too had the same thought its nothing to worry about, like crabs said theyre rubbing on a coral. Do you have any euphyllia?

I agree. Does the fish try to host any coral at all?
