How Long Does It Take to Cure Tail Rot in a Map Fish?

With active treatment, map fish tail rot usually recovers in about two weeks. When you notice tail rot, isolate the sick fish immediately to prevent infecting healthy fish, then treat it with an antibacterial medication bath, for example a 1 percent salt-water bath for 5 to 10 days, and it will gradually recover.

At the same time, clean and disinfect the original tank, because map fish tail rot is mostly caused by water pollution and the tank urgently needs cleaning to prevent repeated infection.
