Sorry the pics are not the greatest. Tough cricket to get the phone to focus on.

I have these but they are brown. I havent seen the blue. The little thing I caught last night was so small and skinny I couldnt make out any tentacles or other identifiers that would point towards a bristle worm. I was feeding the fish the other night and from the rocks came a 4-5 inch + bristle like your pics but brown. As far as I know they are reef safe.....
