ID this worm thing for me? Picture included

[jess128]

I posted here before about a huge worm-like thing that came along with 60lbs of fiji that I got on that bg J&L order that Josh did. There's this one big one and I've been finding a whole bunch of little ones that stick out of holes in the rock. What is this thing and is it good or bad for the tank? I kind of just want to get rid of it, it creeps me out!

I can't just post the picture, it's a long story, but if you copy and paste this address into your address bar it should work, it did for me anyway when I tried it. In the picture the side on the left is the front of the worm, it has a little mouth-like thing on the end (looks like the end of an elephant's trunk.)
