No worries...

She will be alright if you keep the food amount adequate and don't overfeed them~
Swords are more aggressive then platies (eg. 紅滿, 米奇), and especially during feeding time..maybe you can try to spread the food evently in the tank so that other fish might have a chance to eat the food without being attacked by the swords, and try to limits the food to be gone within a minute so that you won't overfeed them.
It is indeed a lovely fish and I really do hope they can produce some little fins for you in a short period of time.
