Hello everybody! I got my betta, Ash, awhile back, and sadly he came with some fin rot. He's in a 5 gallon by himself, so I don't have to worry about it spreading. I've been doing water change after water change to try and fix him up, but it's just not working. I'm about to head off to the fish store, is there anything I can buy that will help him out? I've been looking on the internet, and I've read about quite a few ways to heal it, but I don't know which method is best, or even if they work. What do you suggest?
