White worm in rocks

[Afkomjorgen]

Hello!
noticed this white worm yesterday and got some (not very good) photos today.
I haven’t seen it fully leave the hole in the rock that it pokes out of, and there is some weird detritus stuck around the hole. It’s head doesn’t have any antenna that I could see and it doesn’t have any apparent markings.
It pulls back into hole when disturbed but not at lightning speed. It was poking at some vermatids when I took the photo

Here is a video of its movement

Edit:
Thinking maybe Oenonid or peanut worm ??

 

[Afkomjorgen]

Bump?

Yep, Mr. Peanut.

What do I see:
tube worm
possible vermetid snail
asterina star ( grab and discard- will multiply like mce)
worm - Detritus worm or polychaet

Yep, Mr. Peanut.

Cute until they take down zoas and get caught up in pump intakes and overflow. I lost a bab Bam zoa colony because of them.

I’m sorry that happened. We don’t keep any zoanthids thankfully.

The reality is that there are several types of Aquilonastrea, and most of the ones in the hobby don't eat coral.
