Is this a Zoa, Paly, or something else?

I originally assumed this was a Zoa when I acquired it. As the colony has started to increase and the more I look at it, I'm not so sure. Can anyone nail down what this is?

Definitely not a zoa or paly, looks like a blastomussa.

I think you might be right. Looking at some online images it appears to align. Thank you.
