New hitch hiker. Any ideas?

[Daddynemo30]

Rocks been in tank for a couple months. I added a few new corals a few weeks ago but this wasn't there before. It closes up and looks kinda like a worm head, but doesn't move. But it will open back up fully in like 5 or 6 seconds. Any help?

Have you rule out it being, an (species of) Sea Squirt or Tunicate?


(lol)
Just tossing it out there...
