HI, If you want a pair, I think you can just buy them seperately which is cheaper, (female $10--$20 male $12--$19)If a pair fighters have not breed before,maybe they will fight, can not breed or hard to breed and waste you a long time.You should condition the female, that is important for breeding I think.I will post a topic to talk about to condition the female.I think the male is easier to condition than female.
