He is a bottomless pit. I have him on B fusca roaches right now and he destroys them as for his attitude and habbits I was in a different room and I kept hearing a loud banging noise every few seconds. I walked into my room and saw Bruce slamming into the side of his tank trying to get to my fusca colony in the tank next to him. I have put a visualbarrier between them and the tank bashing has stopped health digs alot of holes and has way more personality than my cranwells pacman the same size. He always has that "who...me?" expression on his face
