Not a clue

Got this from my lfs. Apparently it's rare or something, paid 20 bucks. Looking for an ID, actual rarity, and wondering if it will open up or not. I also added a picture of my starfish eating the thermometer for fun.

not a goniopora.
I would suspect since its closed some kind of blue xenia

I found out a while ago it's sympodium
