Currently in a quarantine tank, my betta has suffered from cotton wool disease. I treated the whole thing with Furan-2 and aquarium salts, and it seems that the holes in his fins have healed up and he started to swim around again. His lips on the other hand have become so swollen and deformed that he has a very hard time eating the food on the surface of the water. Will the situation get any better or will I have to euthanize him?
