My female Betta, copper, was found floating at the top of my 55 gallon today. Fins shredded. Guessing she got into a fight. I have never seen my Betta's fight in the months that I had them, but that is the only logical thing.
She was the one of the 6 original female Betta's that went into my 55 gallon planted. Then I added a few more Betta's. Everything was good for the longest time.
Copper was a silver/pink female Betta. The dominate female of the group. She loved to burrow into the plants looking for a leftover blood worm after feeding :3
You will be missed.
I guess you can say, sh*t happens.
