ID coral please

Got this for myself for my birthday. It's a bluish grey with a hint of green. I don't think it's a month but I'm not sure.
It's the one behind the stylophora. And what's the one to the left of it. The lfs had it growing on the frag rack and gave me a piece for free. Here's a better pic of the top view.

Pretty sure it's a Undata monti and a Spongesodes (might have that spelled wrong)

Look like Jedi mind trick to me, and spongode or hydnophora

If it looks like this it is Undata. This one is mine.
