This worm type thing has popped up on my live rock. I have no clue what it is and I was wondering if someone could help me. It secretes a spider web like mucous from it's "mouth". These are the best pictures that I could get... and I did not down size them so they would be bigger. Let me know what it is and if it is bad.
Thanks....
