I have had LeeLee for 3 going on 4 years. Robust, never been sick, never any other fish with her, never bred, in a 2 gallon glass antique punch bowl, used only purified bottle water, fed every other day premium betta food, cleaned every week, never showed signs of stress or illness. I got her from a breeder friend just for the heck of it. She wasnt breeding quality. I was up rocking my daughter in the chair since she wasnt feeling well, and all of a sudden LeeLee was flipping around the bowl, like she was crazy. She looked like she was fighting herself. She even breached the water 2 times. I went to her to see what was wrong and she just floated to the bottom and now is dead. Her eyes are a bit bulgy. It was sad and scary. I have a male that is in another 2 gallon antique bowl and he is the same, healthy and nothing wrong. I got him at the same time. They have never been together and are not near each other. he seems fine. What happened?
