I inherited a betta that has. Been doing really well for almost 3 years. About 3 weeks ago he started getting a very large white/pink patch on his face. It just keeps growing. I've used Jungle for fungus, have done water changes, salt, and used water conditioners. I just tested and it looks as if the alkaline is too high and possibly the water is too hard. I'm not sure if that is the issue. Jake isn't eating and just hides begins the filter. I'm not ready to explain Fish Heaven to my kids yet!
