What is this worm / anemone tentacle thingy?

Upgraded like a week ago form 120 to 200, kept some water in the old tank, no heating or flow, just standing water, today I've seen this near the glass, when I moved it to a cup it shrank a little bit.
Put it in a cup inside my sump.

Any idea?

Did you get live rock by any chance?

Looks like a peanut worm often confused with Priapulida worm. Peanuts are safe and eat uneaten food and detritus

Shine a flashlight or something at it

It's from my old tank, I didn't add any new live rock to that tank.

That what I was thinking, but on the other end, it really do look like a ***** lol
Priapulida worm also known as ***** worm.

Any way to confirm which one is it?
