I just found this on my live rock. Anyone have any ideas what it is? Doesn't really look like a bristleworm. Is it good or bad?

I have no idea, but it looks freaky as all heck. (bump, I want to know too.)

check the "advanced topic" forum, maybe someone there will know.

Looks kind of like what I just found...

I don't know minimalist. This was found on the live rock nowhere near the glass and is almost 30 mm long. Does anyone know what this is?

Minimalist is right - both his Ophryotrocha and your scaleworm are polychaetes as are the amphinomids which most reefers call bristle worms. Polychaete means "many bristles"so they're all bristle worms.

Ophryotrocha are in the family Dorvilleidae. scaleworms are in family Polynoidae. They're predators on smaller worms, crustaceans, etc. That's a spectacular specimen by the way. If you don't want it I do.

It almost looks like some type of sea cucumber.

Like LeslieH said, it's a Scaleworm.

Thanks LeslieH, I figured it to be a polychaete, but it is very helpful to know the family. Unfortunately, I think this specimen is on its deathbed. I suspect that is why it was easy to find and catch. I don't think I would have ever spotted it on the sand, the camouflage is excellent.
Evolution at work!
Thanks for everyones help. Scaleworm it is!
