So i was doing my nightly feeding and I noticed that my Yellow Watchman Goby wasnt out trying to get some food so i took a flashlight to try and look into the den that he shares with a pistol shrimp. I found the pistol shrimp in another den under a different rock structure but no goby. When i looked at the original den I see a bristle worm but dont know how large it is but it looks to be a good size. My question is could the bristle worm take out my goby?
