HELP WITH ID.

I found this at the bottom of my tank a while back and can't figure out what it is. Some kind of chalice? Please help and thank you in advance.

First picture is with polyps closed.
Second is with polyps wide open.

Chalice coral (Hollywood stunner) A few members have had the same weird polyp extension/coloration.

Sort of looks like a chalice to me, beautiful coloration on it.

Thank you. I was thinking it might be a Hollywood stunner but the polyp extension threw me off.
