What are these things growing on my toadstool?

[Pom]

I bought this toadstool (already attached to a piece of live rock) from diver's den and today I noticed all these things growing on the rock. What are they and should I remove them? Thanks.

Boy that's a good one, hydroids or polyps of some sort.

Sorry need a better images, looks like it could be clove type coral.

Look up colonial hydroids and compare the pictures to what is on your rock.

I was going to take another picture of the white clove things but they randomly disappeared? Now I found this black thing that opens and closes sometimes. What the heck! Should I just remove these corals or what?

Your coral looks pretty healthy. Don't bother them. They want stability.

No no no that tube growing on your torch is a nice feather duster
