My betta Vincent developed fin rot a few days ago. I was so alarmed and YouTubed videos on how to cure fin rot and found a guy who has a betta recovering from the disease. I did a 100% water change, treating it with Stress Coat and Jungle Aquarium Salt. His tank is a 3 gallon so I added the needed amount. Today is day 2 of his treatment and I did a 25% water change with the appropriate amount of salt needed for 25%. The water quality is in good shape and the pH is 6.8. Nitrates and Ammonia are low as well. I’m also keeping him on frozen bloodworms in hopes it’ll help him recover quicker. Am I doing enough to help him get cured? I read some people use Bettafix and Melafix to help boost their betta’s immune system but I don’t want to do too much and end up hurting him.
