what is this funky creature?? Good or bad?

The pics are horrible i know...i will try to describe it...It behaves much like a leach or a worm. It has long stringy tentacles that just flow around...and occasionally slowly try to grab something...I have about 5 of them in the sand with only the tentacles exposed...any ideas...they are a rust - orange/red color...
any thoughts?

It looks like a fire worm but I can't tell by the pics. If it is it shouldn't harm anything.

Cirratulid worm. It's a good thing.

great..hoping it was a good thing...i do have fireworms also...they are more like centipedes if i am talking about the right ones...these are more like anenomes with limp arms and shaped like a worm that tend to wiggle like a sea cucumber when floating...thx for the responses
