with all due respect to the other posters. this is a repost of one of my old posts
Of course as educated hobbyists (which I am sure your are one) we must be able to distinguish the good bristle worms from the bad. We would certainly not want to introduce the Hermodice carunculata
(Bearded Fire worm) into our tanks if we keep corals knowing that
Fire worms are voracious predators that feed on soft and hard corals, anemones, and small crustaceans. It will engulf the last few centimeters of the tip of a branching coral, such as Acropora cervicornis (staghorn coral), in its inflated pharynx and remove the coral tissue from that portion of the skeleton. The worm will remain 5-10 minutes at each branch tip, visiting several, and the branches attacked are apparent by their white ends.
The effects of predation on certain groups can be substantial. Witman (1988) calculated that tissue predation by this worm on Milleporid Hydrocorals (fire coral) exposed 12.9 cm2 per 1 m2 per day of skeleton to algal colonization.
This is very true!! What led me to believe that it was a bristleworm was that it was red with "black inside". Most Fireworms are bright orange with bright white hairs.. Also in IDing worms it is almost impossible to ID without a close up of the head/mouth region
