I really want to breed Jack Dempseys but I don't know the best way to get a pair. Should I buy 4 to 6 and watch them pair off. Or is there an acurate way to sex juviniles? I also want to add "dither" fish I was thinking 3-4 silver dollares and 2 male convicts. Am I overstocking or what.
One more question how long and what size do JD's usually start pairing off?
