Female betta injury

[JAMMYLEYLO]

Hello,
a few days ago my female sorority tank had a fight, one female went crazy and killed one and badly injured another,
tye injures one has an open wound near its gill and has started with cotton wool on the wound, ive done a salt bath and Interprt anti fungal is there anything else I can do? She’s been taken out of the tank and in hospital tank.

Don't use any of Interpet medications, their medication kills all fish even at smaller required dose and make it look like the fish died because of the disease not of the treatment. Aquarium salt will do the trick in treating, preventing infections as well as helping wounds to heal.
I'll leave rest to @Colin_T about the infection and sorority issues, @Crispii should be able to help too.

Regular water changes and aquarium salt are the best thing. Going forward I would remove the aggressive one into a tank on her own as chances are she'll do it again.

I agree
