Hello there. I noticed a bunch of bristle worms that seemed to have appeared out of thin air, just like magic! I know there are "good" and "bad" bristle worms, but I don't know if the ones in my tank are the good ones or bad ones. I included a pic. Can somebody identify what are in my tank, so I know if I can leave them alone or if I need to figure out how to get rid of them. Any and all help are appreciated.
