What are these white polyps

[Phadrix]

Can anyone identify these white polyps in my reef tank? There are about 5 that I can see in various places. Do I need to remove them asap?

Awesome! Thank you! My last mystery creature was a tube worm that seems to have hitchhiked in on the same frag, so, score I guess!

What kind of rock is this? I have definitely found some cool critters on my live rock!
