A goldfish pond is a beautiful addition to any backyard. Installing an outdoor goldfish pond is an entertaining and exciting way to add color and vibrancy to your backyard living area. As a matter of fact, outdoor goldfish ponds have been a staple of Asian culture for centuries. Goldfish ponds add beauty to the garden and provide us with an ongoing education about aquatic life and the ecosystem. In addition to being fun to watch, goldfish help maintain water features by eating mosquito larvae that would otherwise mature into pests.
