Another, Please ID this thread

Sorry for posting another ID thread but I'm not sure what this is. Purchased a torch coral on a piece of rock. Spouse noticed something moving and pulsing. I've tried to do some research but have no idea where to begin. Will apologize for the horrible pics in advance as they are from my phone. The critter is bellow the torch, the "arms" move slightly n pulse from time to time.

Looks like a common bristle worm to me. I wouldn't worry to much about it, as they are a natural part of the ecco system of a reef.

I would avoid contact with them though, they can sting.

Brown spots below torch looks like flat worms

How big is it?
The brown thing is probably a small sea slug, or a nudibranch or a flat worm. I'd pull it from the tank and try to get a better pick.

Looks like tunicates to me.
