I've had an aquarium of some kind running since I was 5 years old. I had a tropical fish shop in my garage for a few years.So I have had literally hundreds of Angelfish over the years. I have always heard that angels can be nasty, but I've never seen it... until now. I've had 2 silver angels in my 46 gallon bow front aquarium for 5 years now. I had a small school of neons and emperor tetras with them for awhile, but the bigger angel kept killing everything new I put in there. It's been 3 years since I tried to put anything new in their tank. My nasty angel has the body size of a good sized coffee mug and the other one is just alittle smaller. They seemed to get alog pretty well. I came home from work on Monday to find the big angel driving the smaller one into the gravel repeatedly. I tried rearranging the tank... didn't work. I had to resort to removing the nasty angel and rehoming him to my 10 gallon Q tank. I know it's not big enough but that's all I have at the moment. Does anyone know why these two tank mates have decided to kill each other all of a sudden? Could I possibly have 2 males that want to breed?:help: I'd like to keep them together, but I don't think that's an option anymore.
