Can anybody ID this stuff on a devils hand?

[scubarich]

Have had this devils hand for a long time...and it has been in this tank and doing very well for months.

Within the last 36 hours this white, cotton looking stuff has appeared on it.

Anybody have any ideas what it is? I've never seen a devils hand do this.

I know this picture is not very helpful and I'm to get a better picture with a real camera instead of my phone, but this is the best I have at the moment. Any hints of what you might think it is would be helpful.

It now actually looks like the coral is "bleached" and not something on the coral, but the devil's hand itself, and it is getting smaller.

Oh, mystery solved.

Oh, mystery solved.

It is reproducing.
