Keeping Koi Fish

If you own a pond or are thinking of adding one to your yard, you have likely considered the possibility of adding fish to it. Though there are many different types of fish that can live in a typical ecosystem pond or swim pond, koi fish are typically the most popular choice due to their appearance and resilience. As leading providers of quality fountains, swim ponds, and pondless waterfalls, the team at Fontana Ponds & Water Features knows that taking care of fish is more difficult than it appears. That is why our team has provided a list of 3 tips for keeping koi fish in your pond to ensure that they stay healthy throughout the year.

Keeping Koi Fish – 3 Important Tips

To keep your koi fish happy and healthy, consider the following tips:

1. Maintain a Healthy Population

While it may be tempting to add an abundance of fish to your pond to enhance its visual appeal, this can quickly lead to overpopulation. To ensure that your pond’s ecosystem stays balanced and healthy, you will need to control your koi population. If your pond has too many fish, this will lead to excess waste, compromising water quality and leading to various problems. In most cases, Koi need 10 gallons of water for every inch of their length. For example, a koi that measures 10 inches long will need 100 gallons of water. If your pond holds 500 gallons, you will be able to accommodate 5 koi of this size, no more, no less.

2. Keep Your Water Clean

Though koi are resilient, they still require clean water to stay healthy. Your pond water should always smell clean and have a sufficient level of transparency. While some algae is expected during spring, it should never grow to an excessive level or cause the water to turn dark green. To keep your water clean and clear, ensure that you have enough plants in your pond and regularly check your filtration systems. The effective use of mechanical skimmers and biological filters can also help keep your pond clean even if it is exposed to prolonged periods of direct sunlight.

3. Feed Your Fish Properly

Koi will feed on algae and insects for sustenance, but they benefit most from the nutrients in quality fish food. Though most brands of fish food look similar, some products are far superior to others. Look for fish food that features high-quality proteins, stabilized multivitamins, and probiotics. In addition to the quality of the food, ensure that you are not feeding your koi more than they can eat in 3 to 5 minutes.
