Beautiful Piece, but what is it?

I found this little guy on black Friday And I fell in love. But they didn't know what it is.
I was guessing A type of blastos? But at the same time I'm not sure. It does have a skeleton if that helps.
The purple parts look like short stubby te Tentacles.
And also I need to know if it would sting Duncan's corals

I can't confirm that it is, but it kind of looks like a pagoda coral (LPS if it is).

 

[Sabellafella]

Leptastrea.
Fun fact: They are distantly related to the Fungiids, Psammocora, and the coscinaraeids.
