TalkingReef said:this is VERY uncommon. there are actually only a few species of bristle worms that will eat coral, adn they will need to get much bigger than 2-3 inches to catch a fish..
i keep them in my tank, and i know hundreds of peopel who have them..
you shoudl be fine...
besides, they are almost impossible to get rid of without killing everythign in your live rock and sand bed.
it should be fine.. i have never seen or heard anyone "first hand" that has had problems with them..
