Can Swordtails transitioned to salt?

I mollies can be easily and heard platies don’t do to well but can’t find much on swordtails. Just a curiosity thin really.

Find out if they’re brackish fish by nature. If so they can like the mollies, if not I wouldn’t try

While it's normal for mollies to inhabit alkaline, high pH environments, and even natural for some mollies to live in brackish environments, I'm not aware of any swordtails living in these conditions. They are a pretty strictly freshwater species, and at best this would not be ideal for them.
