colors 1. Water quality: Although koi does not require high water quality, if we want to make koi colorful and strong, we need to be strict with water quality. Koi is a cold-water fish, the water temperature should be controlled between 22-26 degrees, and the PH value should be controlled between 7-7.2. The best water is light green water, and there should be no feces and food residues in the fish tank as far as possible, which should be cleaned up in time.
2. Feeding: Koi cannot produce pigment by itself and needs to be supplemented by feeding the day after tomorrow. Therefore, it is necessary to feed some hyperchromic feed or spirulina regularly to help Koi absorb pigments.
3. Sunlight: More sunshine can promote the absorption of pigments by koi. So if you want to add color to koi quickly, you need more than 5 hours of light every day.
4. Fish tank background: If you want the color of the koi not to fade, you'd better change the background of the fish tank to a dark color. Because Koi fish change color as their surroundings change.
? The food for the koi to increase the color includes synthetic feed for increasing the color, shrimp for a good harvest, spirulina, carrot, etc. When feeding the feed for increasing the color, attention should be paid to the activity of the koi. It is best to feed the koi when it is most active. Because hyperchromic feeds put more pressure on the digestive system, if they are not active enough, they may suffer from indigestion.
