Pics of my new live rock from Hidden Reef

[trilinearmipmap]

Got this new live rock yesterday.

I am pretty happy with it. The rock seems to have lots of holes and openings in it with interesting shapes. Quite a few things growing on the rocks, I'd appreciate some help with identifying these things.

Overall tank view




Button polyps?




Some kind of polyps or zoanthids?




Some kind of star polyps?




Unknown entity?



Also some tube worms (small) were on this rock and a few things that looked like small red and blue sponges. Several very small crabs, and a swimming thing that may be a small eel.
