I have 4 hitchhikers that we really like but would like to know what they are. Pretty sure the first is apstasia.

The second is very cool. Has red on it tentacles? They curl up one at a time and it looks like its feeding itself.

Third

And fourth pretty greenery

Also have a snail and bristle worm. Had a tiny hermit crab but haven't seen him since the first day. Love finding all these new critters. Thanks for any help.

#1 is a type of aiptasia, not the regular one most people have though. It spreads far far slower. #2 is a filter feeding cucumber. #3 could still be alive, it looks like a kind of coral that is often on Gulf of Mexico liverock. If it is alive you'll be able to see it extend very tiny tentacles every now and then. Stays that brown color though, boring coral #4 is a type of caulerpa, possibly verticillata.
