What is this organism??

[KerriS]

Can someone please tell me what this is? It has been slowly growing out of the live rock. I call it an organism because (as you can see in one of the pictures) it can retract itself when touched and also at night. It is sort of pinkish/purple and white, has feather like tips, and is pretty tiny still. Thanks in advance!

Looks like colonial hydroids, or myrionema hydroids - hard to tell though.

Looks like it could be some pulsing Xenia. Was this rock dead or LR from an LFS?

It could even be a teeny tiny nub of kenya tree

It was LR from an LFS. It gotten bigger since I first noticed it, so it's growing.
