Unknown Chalice

I got this Chalice in a trade from another hobbyist years ago, but don't recall the name. It's a beauty, and I enjoy looked at it especially at night when the actinic XHOs are running. It's orange skinned with yellow mouths, and contrasts with the green chalice behind it. Chalice corals are slow encrusting corals. If you try to frag them, then often break as easily as if you were trying to share a potato chip. Ideally, leave it alone and enjoy what you have is my motto.
