My betta has had fin rot for a month now. He's had very mild cases of fin rot before, and they always cleared up right away with clean water. There's no filter, I clean his tank 100% once a week with a 25% partial in between.
He had a bit of red on his anal fin which cleared up, but his tail is getting worse. Not the whole tail, just one side of it. It's gotten shorter in the last week, but seems to have stopped now. I've increased his water changes, and I've also added an Indian Almond leaf hoping to cure it naturally, but there's been no change. I know it's mild fin rot since he still has more than half of his tail, and it's only affecting that one side. He's eating and acts normal.
Some history, about 2 weeks ago I moved him to the basement from the kitchen. He's in a much quieter room now, but moving to a new location must have stressed him out. He had a bit of the fin rot before I moved him, but it got worse from the stress. The main problem is I'm scared to medicate him since I've read some horror stories on the net about overdosing, or the fish not taking well to the medication. I do have some at home, though. I have Maracyn 1 and 2, as well as Jungle Fungus cure that says it treats bacteria infections as well. I also have aquarium salt, but I'm even afraid to add that since I read that it could hurt their kidneys. What do you think I should do? Like I said, it's mild fin rot right now, so should I just clean his tank 100% everyday, or should I start to medicate him?
