My male has been pretty aggressive since I put the once holding female back in my main tank. He keeps them in the corner most of the time unless I walk by or while feeding. What can I do to spread the aggression out? I have 1 dominate male, 2 not dominate at all males, and 2 females. There is also a juvi about 1.25 inches that hangs out in the bottom away from all of them. I plan on selling the 2. On dominate males soon and have a tank full of fry to get some more females.
