I have a bunch of these little things that look like baby xenia or anthellia but it doesn't grow into colonies. They seem to be sensitive to movement/light and will close up almost immediately. Any ideas what this is?

I would say it's some feather duster tube worm (Sabellidae or Serpulidae)
 
They look almost like feather dusters based on the tubes they are coming out of. Did you get live rock from somewhere?
 
Thanks all! Yes I started with live rock from the LFS but also added rock from another tank I purchased. Thanks for the identification! Glad to hear they are harmless

Looks a lot like a feather duster
 
Feather duster for sure. Good to have around and love seeing them in my tank.
