the koi eat? If you want the koi to be dark, you can feed some synthetic feed. Now there are a lot of hyperchromic feed on the market, so you can choose some hyperchromic feed with better quality. In addition, you can also feed more live baits such as spirulina, shrimp and red worms. Because of the heavy burden on the digestive system after eating the pigmentation feed, some astaxanthin and astaxanthin can also be added to the ordinary feed, which is good for digestion and pigmentation.
Koi itself can not produce pigment, it must be ingested through food. After feeding the hyperchromic feed, they should be provided with sufficient sunlight to promote their absorption. The water temperature should be kept between 22-26 degrees to keep them in an active state, which can also promote their absorption.
. 1. PH value: The PH value of water is an important factor affecting the color of Koi. Generally speaking, the PH value between 7.2 and 7.4 is the easiest to add color. Many people will encounter the situation that the color becomes lighter after buying a few koi for a few days, which is caused by the inappropriate PH value of the water. It's better to test the PH value every day to ensure that the water quality is clean, and it's better to use green water to raise it.
2. Sunshine: As the saying goes, "Everything grows by the sun", and fish are no exception. It's better to provide them with about 5 hours of sunshine every day, which can also promote their color.
