Does anyone know what this is??

I noticed a brown, tube-like thing on this frag. I've seen it open and close, so it's alive. There's actually two of them. It's on the bottom left side of the frag, sorry for the blurriness, best I could do

anyone?

maybe snake polyps or tunicate

Both good guesses, I did a search on both, they look similar.
I'll wait and see, maybe get a better pic when it gets bigger

thanks
