Koi fish can be fun and valuable to breed, but the process can be time consuming. But that doesn't mean it's impossible! To get your koi to breed, you need to create the right environment for them. A clean pond is important for the health of the koi and their spawn. Use a specialized koi pond filtration system to keep the water clean during the breeding season. These can be expensive but are necessary for breeding. You can also increase your chances of the koi breeding by keeping them well fed for the month before you breed them. Feed the koi as much as they can finish in 5 minutes. Whole meal bread, oranges and whole lettuces are great nutritional food options. It's also helpful to give your fish a place to lay their eggs. A fry mat is a flat and sticky mat that gives the koi a place to lay their eggs. If koi can’t find a place to lay their eggs, they won’t always mate. Place the mat in an obvious place at the bottom of the pond.

Feed your baby koi powdered koi pellets after about 10 days. Crush up the koi pellets using a blender or mortar and pestle until they are in a fine powder. Sprinkle the powder over the pond. Pour in enough powder to last the fish about 5 minutes. Feed the koi 4 times per day so they've got everything they need to grow up healthy and strong. It can take a few days for the koi to get used to eating the powdered food and over time, you'll learn how much food the baby koi will eat during each 5-minute feeding session.

Koi tend to thrive in water temperatures between 59°F (13°C) and 77°F (25°C).

If the vent of the koi near the anal fin is swollen, it's a female. If it's smooth, it's a male.
