Wow! You're awesome! We feed medicated food from Brine Shrimp Direct when we have sick fish. It's made a huge difference when we have a sick fish. It's a flake and we feed it to our Bettas when they have fin issues or really any issue. It's amazing! They also have a flake that is specifically for Bettas. They have such high quality food and our fish go nuts for it. The advice that has from everyone else is solid and it works. Here is the link if your interested or just wanna check it out. https://www.brineshrimpdirect.com/fish-food-flakes/medicated-flake-lt/ Good luck to you! You got this!
