Palythoa, Zola this or other?

[will?]

Found these little hitchhikers a little while ago and thought nothing of them, they sort of disappeared but now they’ve moved and seem to be settling in and growing. They seem very small for palys or zoas, but they have just about all the features of them and a mild green colour that’s a little more faint than when I found them. Any ideas on ID would be greatly appreciated.
Thank you!

Apologies, they closed, trying to get a better photo, I’ll get one when they open again and add it below
