I had post a topic about my betta's fin rot on another topic in the betta care section. I now have him in a quarantine tank. I believe his fin rot spread to one of his fins. (The one on the bottom. I don't remember what it was called.)
I have him in a half gallon quarantine tank and added 1 teaspoon of aquarium salt after I mixed it up in a seperate cup. After the salt was all mixed in, I poured it in the tank then scooped him in the cup and put him in.
He keeps flaring his fins at his reflection so I'm hoping he'll stop periodically for his fins to heal. I can see some healing going on though on his tail. It looks like the bottom fin has fin rot only because it's very red and the ends are a little transparent.
I was thinking once his fins heal, I could breed him with a female HM. He's my baby and one of my prides and joys. I'll post a picture of what he looks like later when my stepmom lets me use her Fujifilm camera for a clear image.
I will only apply Bettafix once the bacteria is killed to promote fin regrowth.
