What is this...? Friend or foe...?

After lights out last night I walked past my tank and saw this....

Any ideas on what it is?

I hope the video link works. If not I'll post some pictures, but they suck because you can't see it in action. Fingers crossed that the video works.

Thanks for looking.

could be a few things:
1. peanut worm-super shy and will retract as soon as light hits them, try that
2. nassarius snout
3. bristleworm (not likely though)

Here are some still pics anyway so you can zoom in.

I am leaning towards Peanut Worm.

my bet would be a peanut worm
