Betta Fish: Opal is that patient that refuses to admit that she’s ill

I’m treating her for fin rot. Saturday I noticed a few splits in the webbing between her rays, and I salt dipped her. By afternoon It was markedly worse and she was looking ragged and we did another bath with salt and methylene blue. She continued to deteriorate and Sunday afternoon I was able to procure kanaplex and a hospital tank. Since starting that I can’t believe how fast she’s healed. She’s also laid eggs and built a bubble nest. Maybe she was eggbound but I also tend to think that it’s because the water is completely still and she’s bored AF. After 3 days of kanaplex and methylene blue that was continuously diluted with daily 40% water changes there is zero trace of any torn webbing, I wish I had taken a before picture. Absolutely nuts she could heal so fast, but she will be in here for the full treatment of 3 doses/6 days. This is my first experience using kanaplex but it seems much more effective than dosing in food or temporary baths. I didn’t treat her tank because I have shrimp but I assume it would crash your cycle if you did?
