Worm ID Please

[MedcinMn]

For awhile I noticed my smaller Zoas and rocks being moved and pulled into one section of my tank. Essentially around one rock. Tonight I noticed a "worm" poking it's head out of this rock. Any ID help is appreciated, also if ID'd, anything I need to be concerned with? It is on the right side where the rock meets the sand. Sorry, not sure why these came up rotated.

Small rocks being pulled closer to the bigger rock he lives in, looks like to make a home. I haven't noticed any corals being eaten.

Definitely looks like a Eunicid.

I pulled the rock out he was in and soaked in RO for a few minutes, he came out about 3", I grabbed with a tweezers and it broke in half. I soaked some more, grabbed it with gloved hands and pulled out about another 6" before that broke and he retracted way back into the tiny hole he was in. Apparently he was snacking on my snails as I found about a dozen shells he'd pulled into his rock.

Do these regenerate?

Yes, they regenerate.

UGH! SOOoooo SORRRY!!! :sad1:

I brought the rock my Eunicid was in back to my LFS.. they gave it to me.. they can have it back!!! I'm just worried it had enough time to create more in my tank....

GOOD LUCK TO YOU!!!
