Clown fish with black dot on back?

[Fishman007]

My two ocellaris clowns each have once small black spot behind there 2nd white band. They always eat and are very active. They eat brine shrimp or emerald entree once a day.(all my fish have been spoiled on it because of my angel and puffer not accepting anything else.) ive heard of black ich or somthin like that but i dont know what it is, could this be it?
Thanks

Do you have any LPS like frogspawn, torch, or hammer? If so its just sting marks where the fish touched it they may be trying to host the coral. It's nothing to worry about.

Black ich is tubular and is mostly but not always found among tangs in my experience. I think eric's assumption is quite valid.

I have a green torch, some times they go near it
