Dragonflies and damselflies are just two of the delightful creatures that will visit your water garden. They are the most beneficial garden visitors because they feed upon smaller insects. When you see them hovering over your pond's surface, tail dipped into the water, they are laying eggs.

Snails graze upon algae and rotting vegetation, providing a useful cleaning and scavenging function.
Small amphibians such as frogs, toads, and newts are among the water gardener's best friends. They each play a part in helping to keep the pool environment healthy and they also add greatly to its interest.

Turtles are another welcome addition to a water garden. In natural lakes and ponds, large turtles typically eat fish, but in a backyard pond, they would rather munch on vegetation and fish food. They make very
tame and wonderful pets.

Newts and mudpuppies are the amphibious forms of salamanders. They may visit your pond for breeding, just like the neighborhood toads. You may not realize they are present. They are nocturnal and very shy.

Even in an urban garden, toads and tree frogs appear miraculously when you put in a pond. Although both species live their adult lives within the terrestrial garden, they breed in water. The breeding season lasts from early- to mid-summer.

The most satisfactory stocking rate for decorative fish is 2 inches of fish for every square foot of water surface area, excluding that occupied by marginal plants. This rate of stocking allows for growth as well as encouraging breeding.
The colorful and hardy koi are among the most popular water-garden species.
