Can you help identify some things?

[Osajus]

Hello again,

I was hoping someone could help me identify some things growing.

First up, I think is some kind of stony coral?



Next, I have these tube-like things growing all over. They are coiled once at the base, then extend up. They often have a fine thread coming from them which extend 6-8 inches.





I know these last two are crappy pictures, sorry in advance.

I had this red/black centipede-like worm pop his head out for a few minutes. Bristle worm?



I have had this jelly like thing on my live rock for several months now. It does not appear to be growing or moving. Its a milky white color with green/brown spots.

1. Looks like macro algae.

2. Some kind of harmless tube worm

3. Bristle worm - tank cleaner

4. Sponge - good for filtration

vermetid snails aint they the ones that have sticky spider like silk coming out of their mouths to catch stuff in the water column?
