Bristle Worms

Well, that sure sounds like too many. Is your concern that they will overwhelm other critters and then crash their own population?

2) Can a bristle worm get too large and feed on other things in your tank. A cleaner shrimp has dissapeared in the last few days and I don't have any predators so it is either water quality (Which seems to be fine) or maybe a rogue bristleworm. I know I have too very large worms in my 90g. One has got to be over a foot when extended and another approaching that size. They come out when I feed mysis or silversides to the tank.

We've heard here of cleaner shrimp decimating bristle worm numbers, but not the opposite. Brad has a few huge ones, and he just said to Bob that his cleaners cleaned out the worms - perhaps he meant they ate all the smaller ones only, leaving no more to reach mega-worm proportions?

I'd give your shrimp another day or so to show up, could be hiding (post-molt). It would be a bugger of a rogue worm to eat a healthy cleaner shrimp.
