I had a simular type of thing happen with one of my clowns its actually caused by their hosts. in my case polythoa sp. or my brown button polyps. According to Dr. Daphne G. Fautin and Dr. Gerald R. Allen the darkening of the skin in areas or melanism is caused contact with the host anemone. It also is known to occur with clownfish that host corals, zoanthids and coralimorphs.

Kind of like this? Mine are from the zoas he hosts in, he is fine just spotted from the toxins.

Hiya, The marks on my clown are exactly like that but not as many. I do have a Zoa, but I have never seen the clowns go near it or any of the corals, but they are exactly the same.

Thanks for that.

in the middle of the night you will probqbly find him in a mat of zoa's. The palytoxins are esp. hard on some clowns. The female that is mated with that male has no spots from the zoas but it tears him up. lol

There is also a black ick but it is quite different than the black spots from the zoas.
