Think I got some freebies

[DiverGirl82]

I was at the lfs today and got some macro algae for my refugium among other things. When I was putting the algae in the refugium I noticed these rocks attached to the roots. It looked like they had some closed polyps so I Bayer dipped them and put them in the refugium till they open and I can make sure they're nothing bad. One has finally poked it's little head out. This is some kind of zoa right?
