Ever hear a story like this one?"I have two Bristlenose in a mixed tropical tank. I have noticed over the last few weeks that fish have been disappearing and attributed it to my Red Tail Sharks, but tonight found a very recent formerly healthy fish now dead. The fish was stashed up under the bridge that is the home of my adult male Bristlenose, and was already half eaten. I am now wondering if he is the culprit behind the other disappearances. Has anyone else noticed this behavior?"
I sure have, and I've wondered the same thing. Do I have a killer fish in my tank? It's an easy assumption to make, but is it the right one? Are fish inherently cannibalistic?
