Koi and other goldfish can grow to a large size, sometimes reaching up to 1 meter in length! The best habitat for them is an extensive pond with filtration and weekly water changes. With the right pond size, filter and equipment, koi and goldfish farming is a lot of fun.

Steps

1. 1 Materials needed for a koi pond
   • Adequately large for approximately 2.6 liters per inch per adult fish. Accordingly, you will need at least 65 liters of water to keep one koi carp.
   • A filter that can handle large amounts of waste and uneaten food. You also need a large air pump or waterfall to oxygenate the water.
2. 2 Before installing the pond, you need to prepare a place for it in the yard. The placement of the pond tank is a critical part of the building process. Wherever you decide to install it, make sure it won't leak into yours or a neighbor's yard. Fertilizers will kill the fish.
   • You will need a good pad under your pond. Ethylene propylene rubber works best; it is much more expensive, but the 20 year warranty is well worth it.
   • Fill a container with water and treat the water with a water conditioner. The pond MUST be at least 1.2 meters deep for your koi to winter successfully.
3. 3 General care
   • Some water needs to be changed every week. 10% will be enough. Remember to add a water conditioner after every water change.
   • When the temperature drops in winter, koi hibernate. In colder climates, care must be taken not to ice over the surface of the pond. If a crust of ice has already formed on the water, melt it in several places with hot water. Don't knock on ice. Remember that your fish are sleeping at the bottom and you don't want to disturb them. It is better to bring goldfish indoors in winter, as they are not so frost-resistant.
4. 4 Koi carp feeding. Feed daily, in the spring and summer, two to three times a day with good water filtration. But don't overfeed them. Remove all uneaten food after feeding. Special quality koi pellets are best suited. Dilute their diet with fruits such as orange, watermelon, roasted barley, and boiled sweet potatoes. In the fall and early spring, when the water temperature reaches 10-13 degrees C, give food with a reduced protein content, such as wheat germ food. In warmer months, when the water temperature is 15 degrees or more, start feeding high protein pellets. Stop feeding when the water temperature drops below 10 degrees.

Tips

• Try to place as many fish as possible in your pond.
• Barrels cut in half make wonderful dams, just use your imagination!

Warnings

• Koi and goldfish leave a lot of waste behind, so be careful with the water.
• Do not place stones on the bottom of the pond.Leftover food and waste products will settle on and between them, and you end up with a waste pit instead of a pond.

• Large pond capacity with 2.6 liters per inch of fish.
