Need help with ID

Hi guys,

I recently got a bubble tip nem from the LFS and it wouldn't leave the rock it was attached to for anything, so I ended up getting the rock as well. I did kill the couple of aiptasias that came along but had this small brown flower looking things too. Anyone has any idea what it might be? It's been in the tank for about 2 months now, they don't appear to grow nor to spread to other parts of the tank.

Thanks for the help, cheers.
