How to treat fin rot
Take the affected fish out of the tank.
Start by removing the affected fish from the tank and placing him in a separate tank with clean, fresh unchlorinated water.
You will also need to remove the other fish in the tank to a separate container with clean, fresh unchlorinated water.
Available options: (a). Use a different net to remove the other fish as fish rot can be spread through shared nets. Do not place the affected fish in the same container as the other fish as this can cause the fin rot to spread.. (b). Turn the tap and remove any food that the offending fish ate. Make sure the water does not become too cold.. (c). There are a variety of different types of fungi that can cause fin rot. Neem, mustard, mistletoe, kale, avocado, japanese cabbage, and other arborniferous plants have fungi that may cause fin rot.. (d). Know the proper way to keep your fish cold. While you can either keep your fish outside or make him warm in your home, you should place him in a well-ventilated living tank and make sure he is outside during the day..
