I originally started with one koi swordtail pair, and they recently had little babies. Two managed not to get eaten, and it was one girl and one boy. The father keeps nipping and chasing his son into hiding, and is making moves on his daughter (not sure how well incest goes over in fish lol). Would adding more females help the situation? If the info is needed, they're in a well planted and low stocked 55g.

Yes. Male livebearers only think about mating and will fight with any other males for breeding rights. Fish also dont care about incest so it's good to get livebearers from a couple of different sources.

If it's a dominant or a hierarchy thing, than one or more females won't change the behavior. If it's because he's got the urge to mate and doesn't tolerate another male to do the job, some more specimens would help no matter the gender. For even more males could slow him down.
