What are these transparent organisms in my tank?

Hi all,

 

This is my first post!

 

Please help me ID these clear organisms which are growing on my zoa's and all throughout my tank. I hope the pic attaches correctly!

 

Thanks!

 

 

 

edit: grrrr.. can't seem to get the pic to show. If you click on "gallery", you can see the pic I'm trying to show...

Hard to tell, it's a dark photo. They don't move, right? Zoos look irritated? They look like tunicates to me--relative of the sponge.
