Why are all my koi fish dying?

Poor water quality is one of the causes of death in the fish. The health and well-being of your fish will be affected by the quality of your pond water, as well as regular testing and maintenance.

Can koi fish live in winter?

If the pond is at least 2 feet deep, clean, and has a de-icer in the shallow end, yoko fish can survive the winter. The water in a pond doesn’t freeze, which means that your fish will be able to survive the winter. If your pond is too shallow, you’ll need to add a few inches of water to the pond to keep it from freezing over.

You can do this by filling a bucket with water and filling it to about 1/4 of its capacity. Then fill the bucket again with more water until you have about the same amount of pond water as you had before you added the extra water. This will keep your water level from dropping too low. If you add too much water, your fish won’t have enough room to breathe and they’ll drown.

The best way to prevent this from happening is to make sure that you’re adding enough water at the right time. For example, if you are adding water when the temperature is below freezing, it will take a long time for the fish to warm up and get used to their new surroundings.
