Seriously, Betta_love, if you want anyone to even begin to respect or like you on this forum, you will need to start being more responsible about how you select and care for fish. You've shown a lot of immaturity on this subject by asking advice and ignoring everything, as well as doing the exact wrong things for your Bettas.
Having the money to go out and do breeding is fine and all, but it does not mean it is the right course of action.
Now, what to do about your sick female: Do you have medications at your place? Particularly a fungus and bacterial medicine that "plays nice" together? (Such as Jungles Fungus Eliminator and Parasite Guard?) If not, you need to find out if the "sore" is bacteria based or fungus based, and treat accordingly.
Also, pick up some AQUARIUM SALT (Repeat, in bold,
aquarium salt) and add the recommended dosage to help that section heal. Without more information, it is extremely touch and go. Do not be surprised if your fish dies because you do not seem to be willing or capable of providing the proper care, as you are more concerned with hopping onto the "breeding bandwagon".
Breeding is not for beginners. Period.
(When you have kept fish for at least half of the number of years that you have been alive and haven't had much trouble, THEN you could consider breeding.)
Now, are you going to listen this time, or just piss off the entirety of the forums, again?
