So I was just doing some thinning of Cheto in my fuge and a bristle worm about 3/4 of an inch went tumbling into my display. Right away, my 3.5 inch yellow watchman shot out from under his rock and snatched it up. Well he spit it out a couple of times and now he is just holding it in his mouth. Is this ok due to the nastyness of those bristles?
