I just recently ordered 1 male and 3 female from my LFS, and it seems that one of the "females" is on it's way to becoming a male. And the male that I have seems to know this. I have all 4 of them in a 55 QT, and I'm seeing the male really go after the morphing male. It is seperated from the other three, and gets beat up if she/he tries to hang with them. Would it be smart to just get rid of the morphing male? And if so, I could probably trade it back in to the LFS, and a get a smaller female. Or should I just go with a trio?
