They myth of the evil bristle worm is dying as it should. They are excellent scavangers and even the VERY large ones keep all the impossible to reach nooks and crannies clean. Alot of newcomers and even some who considerthemselves vets lable them bad...for the reason that when something is dead/dying they will consume it. They usually are unattentive and think that the animal being consuimed was healthy, and then correlate the bristle worms with eating things they shouldnt. As you stated the ones that actually consume reef critters we pay for are very rare. Working in LFS's and on reef systems for years now I've still yet to witness any negative behavior from them. I should of just said " They are good"...
