I have a male blue butterfly betta, and when I bought him his fins were perfect. Now, a few months later, the beautiful white lining his navy blue is just gone. It started just a little I got him, and hasn't subsided. The tanks flow is very, very gentle. No tank mates other than small algae eaters and two ghost shrimp. Live plants, sand, smooth river rocks. I assume he is biting his tail, but in all the months I've had him I have never once caught him in the act. His tank is full of plants. I've tried a ping pong ball, new tank mates, everything. Nothing has helped. Any ideas?
Btw- My picture is him when I first got him. All that white is basically gone now.
