Bristle worms -good or bad?

[commodore]

Just noticed what I assume are bristle worms on some new frags I bought and have in a quarantine tank. Should I get rid of them or are they beneficial? Thanks

They are great scavengers. Just don't touch them, the bristles are painful and difficult to remove.

I agree. Leave them and let them clean your tank.

There are many species of Bristleworms. The good ones will remain small, the bad ones are huge. With either one, do not pick them up by bare hand.
