Help with Coral ID

[AandR]

Help with what coral this is? Was sold to me as An ACAN Echinata, but it doesn't look or behave like my other ones. Is yellow, with pale blue almost white centre ( looks dark blue/ purple in pictures but it is not). Just curious. Thanks for your expertise.

It looks like a merulinid of some sort, either a large-polyp Favites or Dipsastraea
