黑鲤鱼鱼鳞的原因是什么？如何治疗？

降低水中亚硝酸盐的浓度可以改善黑鲤鱼的鱼鳞。这是因为如果水中的亚硝酸盐浓度过高，会导致鲤鱼鳞片变黑。一般情况下，饲养锦鲤时，应定期检测池塘水中的亚硝酸盐浓度，并随时降低亚硝酸盐浓度，防止鱼鳞变黑。鲤鱼鱼鳞变黑也可能是由于长期不换水导致水质恶化所致

此时需要立即将锦鲤从原鱼缸中取出，对鱼缸进行消毒，然后将锦鲤放入鱼缸中进行维护

What is the reason for the black carp scale? How to treat it?

The black carp scale can be improved by reducing the concentration of nitrite in water. This is because if the concentration of nitrite in the water is too high, it will cause the carp scales to turn black. In general, when raising koi carp, the nitrite concentration in the water in the pond should be regularly tested, and the nitrite concentration should be reduced at any time to prevent the scale from turning black. The blackening of carp scales may also be caused by the deterioration of water quality due to long-term failure to change water

At this time, it is necessary to immediately remove the koi from the original fish tank, sterilize the fish tank, and then put the koi into the tank for maintenance
