blue zoas with yellow mouth?

[noirsphynx]

I have these zoanthids and can't seem to find an ID on them. They are blue in color with a yellow mouth. I'm not sure if they even have a name but if someone does know any help would be appreciated.

Lucky enough to find them a year or so ago at a LFS but I've never seen any like them since, in person or on-line.
