Fish Pond
Often the reason for having a pond in your garden is to keep fish, often koi, though many people keep goldfish. Both are hardy, colorful fish which require no special heating, provided you live in an area which does not have extremes of temperature that would affect the fish. If fish are kept, pumps and filtration devices usually need to be added in order to keep enough oxygen in the water to support them. In winter, a small heater may need to be used in cold climates to keep the water from freezing solid.
