What's On My Frag

[Sacrifice]

Been out of the hobby for awhile and I know that I've heard of these before but can't remember. I picked up this frag from a LFS a few weeks ago. Today I just noticed this little guy hanging out on the bottom. What is it and what should I do about it?

Kind of looks like a majano anemone, they are the devils spawn. I’d remove the frag and carefully razor it off the plug completely.

Majano, take it out of the tank and superglue completely over it.

Get thee away from me SATAN! Thanks for the quick info everyone.
