Pest Anemone ID? Or....

[Screwhead25]

Howdy folks, I have followed the threads on RC for over 2 years now, but this is my first post ever...This guy came on a zoa frag. He has grown into a more distinguishable size now. Any thoughts on the identity would be appreciated. My first thoughts were that it is a species of pest anemone, but the zoas don't seem to be bothered. Or....?

This looks like a baby fungiid (plate coral). You may have obtained a plate factory, congrats!

Thanks for the reply. Good eye. Looking at photos of young plate corals, this is definately the best match so far...
