plate coral has something growing on it...ID?

[Mikeand Mel]

This is a pic of our plate coral, have had it for a year before this started growing on it.

Is this a coral or nuisance?

Thanks, Mike

Sorry your right....I think it is a pagoda...they both start with P
Anyway, xenia or anthelia, this coral can takeover Ive heard.
If so how do I gwt it off my other coral without harming it(the pagoda)?
