I would really love to breed my jack dempseys, especially because my male has such awesome colors. right now I have two males and one female in a 55 gallon tank. Already had to remove one other male because he was fighting with my nicest one. Do i have to remove the other male before they will breed? He is much smaller than the dominant one, and they don't fight because he is probably not perceived as a threat. But do i need to get rid of him anyway if i wnat them to mate? The big male is around 6 inches and my female is more like 4. thanks for the help
