What eats Bristle?? worms?

[Glennrf38]

I don't know if I have "too many" of them. They don't seem to be hurting anything. And as a matter of fact, they are pretty kewl to watch throughout the tank. My bio load is very small right now and if all the worms do is eat the detrius then I can live with them. My guess is that, yes, I am overfeeding my tank. I will cut back on the feeding for a while.
Did my description sound like the "good" bristle worms to everybody?
