ID this worm plz ?

[Gregs]

hey everyone, been fresh keeping all my life and now im switching to the darkside (for my wallet) - setting up a 220g fowlr and everything is ready to go. i got a load of live rock but as I was moving them from bucket to bucket one of these guys fell out... and then another... and another... all in various sizes.
bad?
good?
if bad, how would i erradicate the critters before throwing the rock in the tank?

thanks,
cheers

i had a feeling this was a bristle worm...
but.. now what do i do? after much reading it seems like people are 50/50 on the danger of these things.

I wouldn't necessarily say they are very bad. They can be beneficial detrivores. The bigger one are pretty gross though.

And heads up on an arrow crab, you might lose snails as well. They are like any crab, opportunistic... when worms run out, snails tend to go missing.

Very wrong.

Bristle worms are harmless tonyour tank. They are scavengers and will help clean your tank.

Leave it.

Fireworms ARE bad.

I don't understand why every one thinks there bad. I remove large ones. But large to me is like pencil size. Other than that they come and go depending on wasted food in tank.

Please tell us why they are so bad
