Bristle worms murder mystery

[Foooz]

When I first got my tank going I had a semi large infestation of bristle worms. We saw up to 6 at one time with a couple in the 5" length range. Did some research loved by some hated by many, not really a problem decided to let them stay. I have looked the last few days, especially during feeding, and do not see any bristle worms. My overflow filters appeared to have remnants of some kind when I cleaned them earlier this week. While I am ok whether they are there or not, I am curious what happened to them. I have a cuc including emerald crabs, some peppermint shrimp, an arrow crab, couple cleaner shrimp, sailfish tang, coral beauty and fox face. I am guessing the arrow crab was the murderer, thoughts?

They're still there, in and under your rocks and in the sand/gravel

The Arrow Crab will be happy to help keep the population in check, as will most wrasses and a number of other fish. Worry not, however - they are still there - in the snad, under and between the rocks, etc.
