I have 2 male bettas (Norman and Rico) in a divided 10 gallon tank. While I was at work tonight I got a call from my daughter saying that Rico had gotten into Normans side of the tank and now Norman is missing part of his fin. The divider is secure so the only thing I can figure is he jumped. I feel just horrible because today I did a water change and must not have put the divider up to the top...
Well I got home and yep Norman has some shredded fins
Took a closer look at Rico and he has a tear also. She got them seperated as soon as she saw it, but I don't know what to do now.
Norman ate normally after this, he swims just fine. I added some stress coat when I got home but what else can I do? Aquarium salt? Will his fins grow back? Increase the temp of the tank? Any help would be greatly appreciated!
