All fighters are naturally solitary and highly territorial, even females.
Males and females together is not a good idea. so many risks.
1.If a male sets up a territory he will defend it aggressively, if females that arent readdy to breed enter his territory he will act as aggressively to the female as he would to a male.
2.If a ripe female enters and they breed his aggression will be even higher because he will be caring for eggs.
3.you also run the risk of your females becoming egg bound because they are continuously in the presence of a male, females can die from this.
You can keep an all female tank, however this also needs to be carefully managed.
If the females are unrelated they will need to sort out a pecking order which means a fight is inevitable. If the females have been prevented from seeing other fighters, their territorial behaviour is increased and the fighting will be much worse to the point of potential deaths.
Sometimes a dominant female will kill the submissive females.
Sometimes there will be 2 dominant females who dont want to submit, these will fight in a simlar way to males (mine locked jaws with each other)
Your tank will need to be big enough and have enough spaces for the submissive females to hide.
getting related females would be safest, as they have grown up together and already sorted out the heireachy
Oh and do not put two males together, it has been done but one male was most likely to be submissive and too afraid to threaten the dominant male. He would most likely have been very stressed being in the territory of a stronger male.
If however you have a huge, heavily planted tank with enough room for each male to happily set out their territory you may get away with it.
