New Tank, live rock critter ids?

[Saltwaternoob89]

Sorry for the horrible pictures, I will work and try to figure out a better way with my phone camera. My tank has just started a cycle and added live rock a few days ago. I have seen a few Asterina starfish, what I believe to be a <.5 MM long flatworm, and a few other things I cant seem to figure out. Brown sack looking thing with maybe eggs? and some stuff growing that i'm not sure. Starfish/flatworms seem to be a debated topic. I don't plan on adding fish for a few weeks, coral for a little longer. Any help would be appreciated. Anything here I need to be alarmed about?


1. Bunch of structures like this?
2. Some sort of squishy sack thing, didn't touch it and it never moved.
3. Same thing as 2 looks like there are small balls in it?
4. Flatworm?
5. Tube things?

1?
2 &3 look to be ball anemones
4? (looks like a frag in the picture)
5 Those tubes are the wicked tubes of vermitid snails.

Nothing horrible, but some people have been plagued with the ones I've identified, if I got them right?

Agreed! 4 might also be a common bristleworm (good scavenger, covered in painful bristles).
@Saltwaternoob89 do you have any other closeup pictures of hitchhiker 1?

tubes on this rock everywhere but I haven't seen any snails

@WheatToast I don't have any good ones, it looks to be some static creatures, there are lots of little ones inside the crevice's on some rocks but no better pictures. in the image below a bunch in that cave.
