ID required please

I wondered if you could identify this little beauty for me. It's currently approximately 5-8mm across and has a calcerous base. There appears to be a second polyp on he rock. They are taking mysis once every other day.

I'm not sure if they are corals or anenomes settled in an old coral/barnacle.

Thanks in advance

Could be Phyllangia americana, the 'hidden cup coral'

Many thanks MX, I was steering towards Astrangia or perhaps phyllangia. Will see how long I can keep them going.
