LR being eaten by bristle worms?

Found this info on the web, though it might help.

One way to capture them is to place a rock with a hollow on the bottom side onto the sand in the evening. Put a piece of shrimp into the hollow to as bait. The next day the rock can be removed and the worms will come out with the rock. There are also traps available on the market. There are also some biological controls. Several species of Wrasses, Copperbanded Butterflyfish, Banded Coral Shrimp and Arrow Crabs are all suppose to eat bristleworms, but I doubt that they will eat the large ones which are
the only ones to possibly be concerned about. My recommendation is to leave them alone unless you have reason to believe they are causing damage. Also be aware that when an animal, such as a clam dies, the bristle worms will frequently feed on the carcass as will any scavenger. Many people misunderstand that the worms are only scavenging and falsely assume that the worms killed the clam or other specimen.
