Keeping Koi and Pond Fish: 3 Basic Rules

3/1/2021

 
If you’ve never owned a pond, or you know next to nothing about keeping koi and pond fish, three basic rules will help you create and maintain a healthy habitat for your new finned friends. We want fish to be happy, and your pond experience to be as enjoyable as possible. Once you become familiar with your fish and their basic needs, you’ll be well on your way to enjoying the full benefits of living the pond life!

​1. Fish Need Clean Water

Your pond water should always be clean-smelling and have good clarity.  On occasion, the water might be green due to suspended algae, or slightly brown due to tannins, or even a bit cloudy after one of our famous dust stroms.
Algae is typically expected in the winter and spring when the plants are not growing aggressively. Once the plants grow, they consume more nutrients from the water, thereby starving algae of food to survive. Ponds in sunny locations experience higher algae growth, but this can be alleviated by shading the pond surface with waterlilies or floating plants like water lettuce.
Keep in mind, algae isn’t necessarily a bad thing. Your pond fish will eat algae off the rocks in your pond so it’s good to have a little of the green stuff. Too much algae can become unsightly, but can be controlled with various water treatments.
If you’re going to keep fish, it’s imperative that your pond have proper filtration. A mechanical skimmer is your first line of defense for removing unwanted debris such as leaves and twigs from the surface of the water. If left to decay in the pond, organic material can cause a host of water issues that could make your fish sick. The skimmer also houses the pump, which circulates the water and helps to aerate the pond.  A biological filter is positioned opposite the skimmer to create the beginning of a waterfall. This filter uses bacteria to break down pond waste, converting it into less harmful compounds that can act as aquatic plant fertilizers.

​2. Maintain a Healthy Population

One secret to making sure your pond water remains balanced and healthy, is to control your fish population. Sure, it’s tempting to add lots of colorful koi and pond fish to your water garden, but you want to avoid over-crowding. Too many fish creates excess waste in the pond water, which in turn can cause water quality issues. As a general rule of thumb, pond fish need 10 gallons of water for every inch of their length. So a 10-inch long fish needs 100 gallons. If you have five 10-inch long fish, your water garden should have at least 500 gallons of water. Keep in mind that your fish are going to grow so be sure to under-stock your pond in the beginning.

​3. Feed Your Fish Appropriately

Koi and other pond fish will feed on natural sources such as algae and wayward insects, but they’ll benefit from a prepared, quality fish food such as Aquascape Premium Fish Food Pellets. Just like other pet foods, not all fish food is created equal. You want to look for food that contains a high-quality protein along with stabilized multivitamins and probiotics. Only feed your fish what they can consume in about three to five minutes, at the most. In the summer, you can feed them twice per day, but in spring and fall you should only feed them once per day. Be sure not to feed the fish at all after your pond water temperature is below 50 degrees Fahrenheit, although you can give them natural treats like oranges, melons, zucchini, and even Cheerios!

Following these three basic rules for keeping koi and pond fish will help ensure that your finned friends have a solid foundation to grow and thrive. You’ll enjoy hours of watching your colorful koi and goldfish swim around the pond, gliding here and there beneath the waterlily pads. It’s a great stress reliever and a perfect activity to enjoy a bit of nature in your own backyard with the family.
