Identification help!

[Quixote]

I have recently begun my first reef tank and my live rock has corals growing on it while cycling. I want to identify what they are. Also my first turbo snails have living growths on them that also look like coral polyps in the last picture.

First picture is feather duster worms. Harmless.

Second picture is aiptasia anemone. Bad. Remove them. Can kill them with kalk paste, super glue, aiptasia x.....etc.

Third picture is GSP, green star polyp coral. Can become evasive if not trimed back periodically.

Last picture looks like barnacle. Harmless.

Thanks so much! How to remove the aiptasia? Can I just pull it or cut it out or will that cause it to spread? There are 2 of them that I can see.

Don't cut them out, it will spread. Cover it with calcium hydroxide (Kalkwasser) made into a paste using a syringe, cover them with pumps off.

Super glue can work to cover them, but using super glue underwater can be difficult.
