What water conditioner did you use when you filled the tank after cleaning it?
Can you send a couple of pictures of her so I can see her condition?
Has she always had that white area on her underside?
Did you use a water conditioner when you cleaned the tank? If so, which one?
I would never recommend Bettafix for fin rot, regardless of what the ads and Google say. First of all, it isn’t a true antibiotic and it’s not really strong enough to treat actual infections. Second, it is controversial. Many betta breeders and fanciers have lost fish after using it, and be,icee the oil damages the labyrinth organ. You can read that opinion here:
Aquarium salt can be useful, but for fin rot ( and columnaris, if she happens to have it) Kanaplex is most effective, with Maracyn 2 being second best. You can also buy them on Amazon. My concern is that once a fish gets sick, they can deteriorate very quickly. If you can find Kanaplex or Maracyn 2 locally, I would treat with one of those. Some Walmarts carry Maracyn 2. You could give them a call and ask. Do a water change to get rid of the Bettafix, and then treat with one of the antibiotics.
Daphnia are a good food, but live or fresh frozen ones are more nutritious than freeze dried. Larger pet stores sell these foods. They are sometimes kept in the back, so you have to ask.
If you have more concerns, just let me know. I’m glad to help. I hope Pebble will be able to recover.
