New tank, several hitchhikers.

Just started cycling my 20g peninsula tank Monday night, then noticed several hitchhikers roaming about today (Friday). My LFS threw in a fiji rock that must have been teeming with life (good and bad).

I think I have a few starfish, a couple Chitton snails maybe? Definitely a few aiptasia (not pictured). And a slug with no shell? I think there's some vermatid worms on there too, but I'm waiting a bit longer to see if/when they open up.

First picture is a asterina starfish. Some are good some are bad. I would remove it to be safe.
Second picture looks to be stomatella snail. Good cuc.
Third picture I can't make out. Does it move?
Forth looks like a collonista snail. If so they are good too.

Thanks for the help! The third one definitely moves. I've been trying to get another picture of him but he keep hiding by the time I get my phone. Finally got one today.
