Any idea what this is?

Im talking about the two circular things right beneath the xenia. They look to have some kind of tentacles.

Small plate corals perhaps? (fungia) How does it feel to the touch? Slimy tissue over a hard skeleton?

 

[noahm]

they look like baby rock nems (Epicistus crucifer), or some kind of shroom. The fact that the oral disc is very smooth with nothing until the tentacle skirt leans me toward anemone of some kind at least.

Could be cup coral, hard to tell without seeing the base.

Hidden cup coral.
