Bristleworms...what are they?

[dansemacabre]

So, bristleworms. I know they are worms, and they are commonly referred to as a saltwater version of an earthworm. So I suppose my real question is...good or bad? I will have a 125Gal FOWLR, but it will soon become a reef (in about a year, I suppose). So, if they are bad (or will be for my reef), how can I get rid of them if/when they come in on my LR? I'm gonna try the SG 1.03 dip and see what that gets me, but if they don't come off, how should I get rid of them if I need to? Thanks!

IMO and IME they are benificial detrivores, there are a couple of species of bristle worm that are coral predators, but they are very rare.
