Swordtails are a bit harder to judge than many other poeciliids. Although they show a squaring of to a degree, it is nowhere near as pronounced as you will see with things like mollies. I still find that using body shape is my best way to judge swordtail pregnancy although their shape changes are a bit more subtle.
