Need worm identification

[AJG187]

I found this little guy in my aquarium tonight and was wording what it was. I don't mind it in there as long as it isn't harmful. It also has a red pulsating line going through its head. Please help. Thanks!

How long is it? Looks like a young fireworm (bristleworm family).

 

[AJG187]

It's only about an inch right now.

Also you can't see very well in the picture but it has two tentacles on the head and small spines along the side.

I would guess Bristleworm.

Looks like a common bristleworm to me.

That's what my guess was too. I also went up to my lfs they said the same thing. So harmless bristleworm? Thank you for all the input.

Yep, unless you touch it. Then it will feel like you've been playing with fiberglass insulation.
