I recently bought a platnium betta male who just passed. I had him in a tank with 2 mollies and a female betta, but they all seemed to get along perfectly. I do believe that I should've taken the female out, that was my stupidity. But my grandma got my attention to the betta's eyes. One was brighter than the other. Today, we noticed that his fins seemed to be torn up, but we never saw anybody hurting him because like I said, they all seemed to get along perfectly. The male molly was the only one who was ever around the betta 95% of the time, but I do think the female betta tore up his fins when we weren't paying attention. Any thoughts?
betas aren't meant to be in the same tank together like male and male will fight but females together don't I did research and found out they can be together the chances of one of them dieing is slim it is possible when you were not paying attention the male could of attacked the female and the female could of got (revenge) or nibbled him back but that is my theory
