I have african peacoks in a 55 gal with tons of rock work. I have a few females in with males, as we all know the females are not as attractive as the males. I have heard of people doing all male tanks and i was wondering what others opinions are about doing this. I do realize all the agression issues but i have 3 large males and 3 med males with 2 large females and one small female and they are all fine no torn fins no real agression besides the occasional stand off. My main concern is the loss of color and the possible health side effects of having no females. Your opinions and input would be greatly appreciated.
