? The fading of goldfish itself is a natural situation. From birth to the prime of life, the body color of goldfish will become more and more gorgeous, and the color will become dim after old age. This is a very natural phenomenon. In addition, goldfish will fade because of insufficient light, too low or too high water temperature, malnutrition, insufficient oxygen in the water and other reasons.
1. To prevent goldfish from fading, proper illumination is very important. Illumination can increase the body color cells of goldfish, thus making the color more gorgeous.
2. The water temperature should not be too low or too high. The most suitable water temperature for goldfish to grow is 22-24 ℃, and the fastest water temperature for discoloration is 28-30 ℃. When the water temperature is high in summer, it can be properly fed with feed that can increase body color.
3. When the dissolved oxygen in the water is more than 3 mg per liter, the goldfish will color quickly, and when the dissolved oxygen is less than 1 mg per liter, it will fade easily.
4. Attention should also be paid to the nutrition of feeding. Malnourished goldfish are easy to fade.
5. Use color enhancement lights. The use of color enhancement lights can make goldfish look more beautiful, which is one of the reasons why many people buy goldfish from the market and find that the color is not as good as when they buy it.
6. Feeding pigmentation feed, regularly feeding goldfish with some pigmentation feed containing zeaxanthin and carotene can also make goldfish more colorful and avoid fading.
