I read somewhere that once the bristleworm is established, for every 1 you see, ten more are hidden that you don't see.
One night as I was feeding the lps after lights out, I saw this orange liquid detritus come squirting out from a live rock and upon focusing my flashlight on the rock, I saw this huge orange worm retract into the rock. That was scarey

to think of the bristles he could throw out, he was probably about 6 inches long, judging by his width. I have prefilters on my powerheads and frequently when rinsing them out with my bare hands, I feel bristles in them which leave a prickley jagging feeling for a day or so afterwards.
