Bristle worms are crazy. They look freaky and they can be bad for an aquarium, if you have the wrong type.
Some creatures eat bristle worms, just in case you need to get rid of them for any reason. I used to have some small bristle worms in my aquarium, like shown in this video. But I never really got rid of them and I think they’re probably still in my aquarium. I’ve never unleashed an Arrow Crab upon them.
After watching this video, I’m wondering if I maybe should.
