I just bought a 15 gal
. tank. I have 4 Blue Flame Tetras and another two tetras. I just noticed today that one of my Blue Flame's has fin rot. He seems pretty lonley and although I knew that a few fish might die, it's making really sad to know that I could have prevented this.
My tank is cycling right now. I do water changes weekly, clean the gravel and the glass. I added all the chemicals needed. The food I use to feed my fish is flake food. While cleaning the tank today, there was a lot of left over food so cleaned it all.
If you have any advice on how to stop this fin root or any good medication please tell me! I'd love to hear!
