My steel blue female betta had to be put to sleep this morning . She had fin rott, and even though I treated it with the best meds possible, it progressed into body rott. I put her to sleep humanely. Is there any way to stop fin rott from progressing on my other fish in the future? All of my other fish but one are very healthy in clean tanks. Any help will be appreciated. Thanks ahead!
