My betta went through fin rot about two months ago, but since then he's been perfectly fine. He suffered quite a loss to his bottom fin though. A few weeks ago, I started using melafix to help him with the fin growth (it didn't seem like it was going to grow back on its own) and it worked amazingly, however just a week later the piece of his fin broke off again. Now, all of his fins are starting to come off. It's definitely not fin rot because he's acting completely normal (flaring at the fish beside him, eating all of his food), but melafix isn't helping at all. And by all of his fins, I literally mean every fin is starting to shorten and gradually fall off.
