Anyone have an idea what this one is called

It's called Palythoa (; but they remind me of one named Rainbow Sakura.

But not a definite?

Unless it's lineage can be traced straight back to whoever gave it the name it will probably never be a definite. Palythoa and Zoanthus coloration for "named" polyps can have many morphs that look near the same as each other. It looks very similar so you could call it a morph if you'd like, that's what it looks like to me. No matter it's hobby name, it's a good looking Paly.
