there are 100's of different types ofworms out there, are you sure they don't eat living things??? Fireworms are a type of bristle worm which is bad, And from his pic it looks red. This hobby has gone from they're good keep them to they're bad get them out to they're good again lets put a name on them and sell them to make money and back. But you would have experience that only being in a year. Don't believe everything you read, and don't give advice when you don't know what your talking about!
With Hobby experience since jan 05 you must know what your talking about right. Don't post like your the authority when your a newbie come on.
I personally saw a worm digging a hole in a sacropyton toodstool. No the coral was no dead or dying, polyps were out coral was fine. Worm ate a hole in it. But all are safe?
