Plate coral? Or maybe not...

So, once again got something from a non english speaking LFS, and I am not sure what it is. It has a greenish tint with purple around the heads of the polyps... Any idea? Thanks!

Looks like goniapora. The purple one.

Thanks for the ID. That looks exactly like it. Sounds like they are almost impossible to keep, should be fun... Thanks again...

Yup, purple flowerpot coral. Had one just like it for about 3 months and mysteriously died. That one looks like its starting the downward spiral, notoriously hard to keep!! Good luck
