Shubunkins and Comets are good choices for a garden pond.? They do not require special feed and can handle winter temperatures.?
Fancy fish, such as Orandas and Ryukins also can live in an outdoor pond, however they cannot swim fast enough to get away from predators.? Also they may have more health problems and are less able to tolerate extreme winter temperatures.
Koi are very popular for water gardens.? They require deeper water (3 ft.) and excellent water quality.? They tend to uproot water lilies or eat their new growth.? For that reason Koi are often kept in ponds without aquatic plants - where the fish are the main attraction.
Water gardening requires the least amount of maintenance of all types of garden projects if properly planned, installed, planted, and stocked. Fertilize water lilies monthly during the growing season, and trim browning leaves and spent blossoms of the water lilies. Plants may need to be divided and replanted. Clean the filter media at the same time that you fertilize the plants.
Spring is the best time to clean a pond, but doing this too often will upset the pond's natural balance. If debris has built up on the pond bottom, smells of foul water, has black or milky water, do a thorough cleaning. Remove fish and place them in a holding tank in some pond water. Keep the fish in a cool, shady area. Remove plants, keeping wet and cool- divide and replant, if necessary. Replace filter media, if necessary, keeping old media wet and place in pond loosely around "new" filter for beneficial bacteria to transfer. The old media can be removed after 2-3 weeks. Do no scrub pond walls, but hose off loose debris and remove. Refill pond water, remembering to dechlorinate.
