In my tank i pick up a piece of live rock and found about 3 to 4 little orange worms that look like a centipedes. what are they and are they harmfull. if so who to i get them out. :help:
Probably bristleworms, which are beneficial in cleaning up detritus etc. Most likely WILL NOT cause any harm at all. Use the search feature and search for bristleworm you will find tons of information.
