Evening, people. Sadly, my Betta of three weeks has succumbed to dropsy. He was sick from when I got him from the store, but he fought til the very end. Anyways, I'm considering my options on what to do. There are no other inhabitants in the tank and is completely empty. I was thinking of waiting a few days and treating the water with API General Cure, Erythromycin, Melafix, and maybe Hikari Prazipro to get rid of any remaining parasites/negative bacteria. Am I doing something wrong and am I missing something? Please, advice would be great.
