Bristle-worm Infestation

[AAReef13]

My tank has always some bristle-worms, but I really only saw them a couple times for the first year of my tank. In the past 2-3 months, i've noticed the population of them skyrocket. I see them during the day, during feeding, during the night. Some of them are getting huge. I see them all the time and while I know that they aren't bad to have, I really don't like seeing them as much as I do.Weird looking. I'm now looking for ways to get limit their numbers. I got an arrow crab today, a fairly small one, but did more
research and found a lot of people saying they just kill fish. I've got a Green Mandarin who is doing well but is slow and I don’t want him to become lunch. Does their slime coat help against crabs? I also have a cleaner goby who is small and slow. Any suggestions are appreciated.

Various companies make 3D-printed bristleworm traps, so that's always an option. The worms shouldn't go after live fish (the arrow crab on the other hand...).
