Can you identify these hitchikers?

I got live rock two days ago. Many hitchhikers came with it. (The LR was cured in case you are wondering) I've read the hitchhiker post but I can't connect the pictures with any of these hitchikers.
The first I know is an anemone. It however does not look like the pictures in the hitchhiker thread. What is it's name and is it harmless or harmfull. This pic is a day old. Today it grew a stock. (well you can see a stock not sure if it grew or was just bunched in.

These hitchikers I have no idea what they are. what are they and are they harmless or harmfull (note: the bottom one has now moved his way to the top for better lighting I guess)

Now this I know is a brittle star and is harmless. Just wanted to post a pic of him because he's really cool and his arms are very long. (this is just one, there is another one that lives on the other side of the tank)

There are two worms that only come out late at night. I haven't had the chance to photograph them yet. I will try to get pics of them tonight if they come out. One is about 7 inches long and swims at the top of the tank. looks like a piece of spaghetti. I can't describe the other. I'll post pics of these tmrw if I can get pics tonight.

Is the brittle star green ? If it is - they're predatory and will eat your fish ...
Cool pics though.

I am not 100% but it looks to me as if it might be Mojano, spreads like wildfire and I would not have it in my tank.
Wait for others to reply though so you get an accurate response..

No he is brown, and the other one is black.
So it would be smart to remove the mojano from my tank?

If that is what it is. Make sure you get a positive ID.

well the first pic is defintly a rock anemone the second hitchicker is an aiptasia-or nucience soft coral and need to be killed with a little joe's juice 3rd is in fact a green brittle star howevr like ALL britle stars hes a scavenger and will eat alge detirus and any dead animals he can find so i wouldnt be worried if fact you lucked out with a free star. one time I added some cured rock next thing i know i have a mantis shrimp (stormropod) destroyed my 200 gal tank so from now on UNCURED rockk only

I would love clearer pictures of the brittlestar...and an estimate of size. I really would not worry about it.
The green brittlestar, Ophiarachna, is a KNOWN predator in the wild. But what you have is very unlikely to be any problem at all.
