I don't think those are glowing eyes, I think that's a white stripe behind the head of the worm.

I know some similar worms that are Dorvilleid worms or Eunicid worms, so do you know how many tentacles the thing has on it's head? If it has 4 tentacles, then it's a Dorvilleid, and likely harmless/beneficial. If it has 5 tentacles, then it's a Eunicid (and in this case, I'd remove it):

It's definitely a Eunicid species, but not necessarily a bobbit (in fact, I'd guess it's likely not a bobbit, as those tend to burrow in the sand) - there are a number of Eunice spp. and Leodice spp. that look like this (i.e. that look similar to the bobbit, Eunice aphroditois).

The handful of species that I've looked at that look like this are probably not ones that you'd want in the tank though.

Sure seems to be glowing and it was fast. I can’t get the video to upload but here’s pics

I was able to watch the 27 second video (and the 8 second video too) - yeah, the white stripe behind the head is reflecting the heavy blue lighting (the rest of the body seems to be "glowing" too in the videos, but the white stands out more).
