Hairy mushroom and looks like a relative of aptaisia

I disagree about aptasia. I think they're yellow polyps, or possibly cinamon palythoas (hard to see).

Some kind of hairy mushroom, it looks like a Rhodactis inchoata.

Thanks Folks. I know the pic is bad I will try and get another. Any guesses as to what the brown membrane covering the lower right portion of the rock is? There is a hole in it that houses about five baby brittle stars in it and around 25 baby brittles have shed from the rock since i placed it in the tank. too cool

The polyps are probably palythoa or zoa. Guess on the grey is a sponge. The stars are probably full grown. They like rock and sand beds. Beneficial and neat looking.
