With two males in the 50, I recommend keeping a very close eye on the level of agression, but the alpha male probably won't harrange the sub male too badly until the first spawn. I think Kaycy's method would be to put all four in a 15-20 long, and when two of them pair off, move the other two to a second tank. I have taken this approach with good success, and always end up with multiple spawning pairs by it. Bob
