bristleworm

be careful if your gonna try to remove that thing

that is certainly a eunicid worm. I had one that lived in the reefbowl for two years straight. Started out 3 inches long, grew to almost nine and stayed curled up in LR holes. Was a frag stealer and decent scavenger, I'd rather not have any more in picos or nanos after the ordeal we went through. Dr. Shimek helped me ID mine, or else I would not have known. Should have 5 whisker-like apparati and two powerful cutting jaws on opposing sides... eunicidae.

thanks brandon. that is exactly what it is. Had two of them that i noticed while cycling the lr thought they had died off during cycling they dont seem to be bothering anything (yet) the teeth look like spider teeth and i have watched it "chew" on the lr did a search on the web for them and they can get quite huge if it lives it will def out grow my tank
