黑色金鱼变色变成红色金鱼有什么问题？

黑金鱼变色是黑金鱼的正常生长发育现象。饲养者无需担心或解决。黑金鱼由于黑色素细胞的增加而变黑，但大约三年后它们会逐渐变成橙色。这是因为金鱼在个体发育过程中经常伴随着变色。处于幼年阶段的各种金鱼都是相同的灰褐色，但由于色素细胞在鱼体的颜色中消失，这些变色过程的中间状态形成了斑驳的金鱼

正常生长期间变色的原因如下：

1。遗传因素：如果亲鱼早变色，那么亲鱼也会早变色，否则会晚变色

2。水温因素：一般来说，当水温高时，金鱼变色更快，当水温低时，金鱼变色更慢

3。光纤因素：光线通过金鱼的眼睛刺激神经中枢，从而影响其颜色变化

4。营养因素。实验证明，营养会影响金鱼的颜色变化。用动物性食物喂养的幼鱼，如水蚤、蚊奶昔、虾等，往往会迅速变色，体色鲜艳。当喂食大米和面条等商业食品时，幼鱼的颜色变化缓慢，体色也不如前者

即使是看起来颜色纯正的黑色金鱼，在饲养一两年后也很可能会逐渐演变成红色。然而，养过金鱼的鱼友对这种现象很熟悉，这就是为什么纯黑色金鱼更贵的原因

What's wrong with the discoloration of the black goldfish to become red goldfish?

The discoloration of the black goldfish is a normal growth and development phenomenon of the black goldfish. The breeder does not need to worry about it or solve it. Black goldfish become black due to the increase of melanocytes, but they will gradually turn orange in about three years. This is because goldfish are often accompanied by discoloration in the process of individual development. All kinds of goldfish in the juvenile stage are the same gray-brown color, but because the pigment cells disappear in the color of the fish body, the intermediate state of these discoloration processes forms a mottled goldfish

The reasons for discoloration during normal growth are as follows:

1. Genetic factors: if the parent fish discolors early, then the parent fish will also discolor early, otherwise, it will discolor late

2. Water temperature factor: generally, when the water temperature is high, the goldfish changes color faster, and when the water temperature is low, the goldfish changes color slower

3. Optical fiber factor: light stimulates nerve center through goldfish's eyes, thus affecting its color change

4. Nutritional factors. Experiments have proved that nutrition will affect the color change of goldfish. Juvenile fish fed with animal food such as water fleas, mosquito shakes, shrimp and so on often change color quickly and have bright body color. When fed with commercial food such as rice and noodles, the color change of juvenile fish is slow and the body color is not as good as the former

Even the black goldfish, which looks pure in color, is likely to evolve into red gradually after one or two years of breeding. However, the fish friends who have raised goldfish are familiar with this phenomenon, which is why the pure black goldfish is more expensive
