is worm ok in reef?

[ireven]

I saw a long worm in my reef tank last night. It was very long.
at least 2 inch long with thousand legs. And it's yellow with brown colored.
what kind of worm is that? and is it bad?

Probably some type of bristle worm....very few are harmful and most can be a positive addition.
