Bristleworm ID

[Darkxness]

Hey everyone, just picked up my marine tank a few weeks ago and cycle completed, added some hermits & snails and found this guy in an extra shell I got for the hermits.

Common bristleworm or something to be worried about and remove? It hasn't moved out of the shell yet so easy to remove if required.!

Sorry for the blurry photos it was moving around a bit.
Thanks in advance!

Thank you, appreciate the reply.
Still 50/50 about if I should leave it in or not

Got a few in my tank too, usually came out during night. It eat any leftover food does not harm corals so I will say leave it.

Are the common bristleworms the ones that can possible sting?

They all sting.
