Hello everyone
I am coming to you here because I am new to saltwater and have hitchhikers that of course came in on my LR. I know I have bristle worms I just don't know which species they are and whether or not they are the evil ones. I am hoping y'all could help me ID these guys. I really appreciate the help.

Evening Reefers - I bought a zoa mix rock today from the LFS. I put it in my QT.

Please could you confirm my suspicion...

2x Aptasia?

___________
I'm not sure that kind this is...
Unknown snail

the underside - looks like it has a second shell???

Hello friends
I had some things show up that I have not noticed except for the last pic, a source a while back told me something about it being jelly fish... Lol. It hasn't grown or moved in over a month so I'm not so scared.
Here's some pics.

i know that one was mostlikely a coral but never the less, a hitch hiker.
And this last one is the "jellyfish" it has like little wiskers at the end I guess you would say, they're really small tho, kinda like a lot of polyps

That's just a common bristle worm. No worries.

Thanks Cloak! What you think about this weird growth near my sponges. I can't seem to find anything on these purple/black orb thingys.

It has a neon green top though

I'm not 100% sure, but that may be a sponge as well. These do come in a wide variety of colors, shapes & forms.

My Xenia also have a brighter color, especially after I frag them, or they out the water and back in again. Wait a couple days, I'm sure it's colouration will change.

i also have 3 of these clam looking crustaceans...

Some clams, bivalve mollusks, not crustaceans. I have quite a few clam hitchhikers that survived in my tanks and help to filter the water.

Some anemone.

Green star polyps or some antheliid similar to them.

Anemones, too.

A hydrozoon that can strobulate jellies from its oral disk.

Need an i.d. On this strange green thing

Need an i.d. On this strange green thing

Hey guys, I'm sure someone will know what this green thing is? I'd guess it's some form of algae but I don't know if it's good or bad?
Hopefully the link works!

This one looks like a bunch of Hydroids too IMO.

True, I didn't see them right the first time because of the image quality. I took the hydozoans for the tentacles of an anemone...
