It’s a 20gal and I have 6 swordtails and 3 Molly’s

All the other fish are perfect and active. I recently got this one. It seems to have been hurt before it has scarring under and is missing one fin.

I noticed this on one of my swordtails and I’m not sure what the best treatment for this would be. I’m not sure if it’s from the other fish or he hurt himself or something else. He’s staying near the top of the tank and isn’t that active only moves around a lot for food.
