If you have placed your fish into a freshly filled tank, chances are that it could be dying because of that. The only option you have if your fish is dying from the lack of bacteria in its environment is to try and place it in a tank that has already been cycled.
How can you save a dying fish quickly?
Simply cleaning the tank and changing the water may help immediately save your fish.
- Put your goldfish in a separate tank while cleaning and replacing the water.
- You should clean the tank once a week to keep it from forming bacteria.
- Remove 15% of the water, all of the gravel, and any algae you find.
