worm ID please

[atvdave]

Was looking under my tank today and seen this long worm. I have always seen them before but never this long. What is it and is it safe in a reef aquarium?

It's about 2 feet long, maybe more.

anyone... will he do harm?

I think you're going to need a better picture for someone to help ID.
