Coral hitchhiker?

[Fishyfisho]

Hi all, I looked into my tank a week ego and saw this! The only coral I have in this tank is a leather toadstool coral and candycane coral, so it was not from them.. Does anyone know what it is?

Looks like alveopora... hard to tell though. Can you get a better close up photo? Are there's mouths in the centers?

 

[Fishyfisho]

Yes there is mouths these are the best pictures I could get because it's really small

From your pics it looks like alveopora:
