Watching your fish glide gracefully and happily through the pond is a sight for sore eyes after a long day and/or week at work. But do you have a pond that promotes the health of your fish? Several factors influence whether a pond is habitable by fish, so before you stock your new pond or choose a few new finned friends at your local pet store, take a few minutes to assess your fish’s dwelling space as it relates to pond fish health. Healthy Goldfish and Koi in an Ecosystem PondSize Matters  It all starts with the size of your pond. You need to make sure that it is large enough to support the type of fish you want (whether that’s Koi or goldfish) and their growth potential. Pond fish generally need 10 gallons of water for every inch of their length, and you have to be ready for them to grow larger, so be careful not to overstock, no matter how tempting this may be! Some pond experts go so far as to recommend only ½ inch of fish per 10 gallons of water as a maximum stocking density. You’ve probably seen ponds crowded with two or even three inches of fish per 10 gallons of water and the fish seem to be fine. However, the density and ecological strain of this kind of fish load turn these ponds into fragile systems. The fish tend to grow more slowly and disease can become a too-common occurrence. Too many rats in a cage, so to speak. You won’t be able to salvage sick fish in a pond that’s overcrowded. Eventually, Mother Nature will pick off some of your fish (mostly likely your favorites) to achieve her ideal stocking density based on the environment the fish are in, and then the remainder will recover as if by magical intervention. Reduce the number of fish if your pond is over-stocked before Mother Nature handles this crucial step for you in a manner you may not appreciate. Good Morning, Sunshine  Some aquatic plants that tolerate shade include Taro, Papyrus, Horsetail, Cardinal Flower, and Lizard’s Tail.Ponds that have at least some sunlight are also beneficial to pond fish. Valuable vitamins are contained in sunlight. Sunlight also helps the plants in your pond grow, thereby reducing nitrates in the water. Unfortunately, you can’t just up and move your pond, so if you have a shady-place pond, add shade-loving plants to help balance the water. Aquatic plants play a critical role when it comes to enhancing pond fish health. Two Feet  When it comes to pond depth, Koi and goldfish aren’t really very picky. Just be sure that the pond is deep enough (generally about 2 to 2 ½ feet) to give the fish a chance to get out of the way of predators. Or you can opt for a cave network within the pond to allow them to hide when need be. A Balancing Act  The quality of your water is critical to pond fish health and you want to make sure your water garden is balanced. The proper mix of fish, plants, filtration, circulation, and rocks and gravel all provide an important role in your pond’s ecosystem. Work with Mother Nature, not against her, and you’ll find you spend more time enjoying your pond and less time maintaining it. Now, doesn’t THAT sound like a dream come true?
