Earlier today I was at the store picking up some things for my aquarium when I spotted a Betta in a little cup. The poor dude has almost no fins to speak of (I'm not even sure if it is male or female!). So, of course, I had to take it home.
The trouble is that I'm not particularly familiar with Bettas (I have Tetras and a Hatchet fish). I'd love some advice on treating this severe fin rot as well as sexing the fish. I know the hospital tank is a little small, but I would like to add the Betta to my 10 gallon with the 4 Tetras and 1 Hatchet fish. If that isn't an option, I also have an empty 3 gallon which I could use after the fish is better.
So, long story short: any advice would be greatly appreciated.
