My betta, Picasso, who lives in a 3 gallon tank. He has been suffering from fin rot for 2 weeks or more, and I've read multiple articles to heal his fins. Now, I add API Aquarium Salt to his tank once a week. His tank is cleaned once a week too. He has no other tank mates and only 1 Java Fern in his tank. So far, he seems to be healing well- There is transparent membrane forming on the tip of his fins and they seem to be regaining color. Does anyone have any tips on how to heal faster? Thanks!
