I'm in the process of using a bristle worm trap but my cleanup crew is going nuts trying to get to the bait. I've read all the pros and cons so I'm on the fence. I've never seen them attack any of my corals though. Their ugly but since the freaks only come out at night I'm not to concerned. I'd get a wrasse but the l once had a six line that attacked and killed a crocea clam that my wife loved.
