About two and a half weeks ago I noticed that the edges of my Betta's fins were ragged, but they weren't black at all. I treated for ten days with Aquarium salt, 1/4 tsp in a half gallon, and put him back in his large tank. He lasted in there for about four days before a huge chunk of his tail came off and I began to see some blackness around the edges of his tail. I'm treating with Jungle Fungus cure now (good for bacteria too, the box says), and the blackness is almost completely gone, but he's still losing his tail and there are chunks missing out of his fins now. Can anyone tell me what's going on?
