What sould you do when your fish floats to the top of a tank?

The first thing you should do is check the water quality to make sure that it is within the proper parameters for your fish. Test the water for temperature, pH, ammonia, nitrite, and nitrate. If any of these parameters are off, adjust them accordingly.

* Lethargy

* Loss of appetite

If you suspect that your fish are sick, treat them with the appropriate medication as soon as possible.

3. Remove dead fish.

If you find a dead fish in the tank, remove it immediately to prevent it from contaminating the water. Dispose of the dead fish properly by flushing it down the toilet or burying it.

4. Maintain the tank properly.

To help prevent fish from floating to the top of the tank, make sure to maintain the tank properly. This includes:

* Cleaning the tank regularly
