If your pond is not deep enough can fish spend the winter in a swimming pool?
No, fish cannot spend the winter in a swimming pool. Swimming pools are typically not deep enough for fish to survive in over the winter, and the water temperature can be too cold for them. Additionally, swimming pools often contain chemicals that can be harmful to fish. If you want to keep fish over the winter, you should do so in a pond or aquarium that is deep enough and has a consistent water temperature.
