Another ID for a new to hobby

[Projecttrinh]

Hello,

Live rock was from a guy who had a healthy reef tank. I put some in my sump. Can someone ID the below? Aiptasia?

Sorry I couldn't find a way to take without the led reflection.

Another one, I saw it retract in the stem

Also can snails ID these white things

Yes looks like aiptasia, white things probably Pineapple sponge

#1 - Yes, that's an appy.
#2 - If it retracted into that tube, it's probably a feather duster.
#3 - Pineapple sponge.

Thanks!

What are suggestions to get rid of aipstasia, looks to be strictly in sump. Can a peppermint be put in there? Or just manually remove?


From what I gather, feather dusters is ok to keep? What about pineapple sponges?

I had a single aipstasia hike in on my chaeto when I got it. I killed it quite easily with a bit of vinegar, slowly dribbled right on top of the little jerk face.

Feather dusters are good. Sometimes their tubes get to be messy, but I don't mind that. Pineapple sponges are great too. Both of them will help filter out stuff from the water column.
