Like many in this hobby I enjoy just watching the tank to see if anything pops out. Well I noticed a small bristle worm.. about inch and a half long about 1/8 inch think maybe even smaller then that just moving along on some live rock shortly after lights out.. anyhow what's everone opinion. I know I've read enough that they pose no real threat to my reef tank but... i desided to google them in stumbled upon many forums about poeple trying to get rid of them.. any ideas or thoughts would be appreciated.
