Can goldfish be dyed and what colors do goldfish have

OK. However, the technical difficulty is higher.

Goldfish and crucian carp belong to the same species (carassius auratus) taxonomy, goldfish originated in China, also known as "golden crucian carp", similar to carp (cyprinus carpio) but it has no mouth whiskers, and is an ornamental fish evolved from crucian carp. There are many varieties of goldfish, the color is red, orange, purple, blue, ink, silver white, five flowers, etc., and it is divided into four strains: literary species, grass species, dragon species, and egg species. In the 12th century, the genetic research of goldfish domestication began, and after a long period of cultivation and continuous optimization of varieties, goldfish from all over the world are directly or indirectly introduced by China.

In the history of human civilization, Chinese goldfish has accompanied human beings for more than ten centuries and is the earliest species in the history of ornamental fish in the world. Goldfish is easy to raise, it has a strange posture, brilliant colors, generally golden yellow, and beautiful shape. Goldfish can beautify the environment, is very popular with people, and is an ornamental fish with Chinese characteristics.

Goldfish in China are mainly developed on crucian carp. After the introduction of colored carp to Japan, it was highly valued.

Yes, but it's not very good, there is a kind of fish food, as long as you eat it, the fish can maintain the original bright color, because the fish food contains astaxanthin, and the fish can penetrate into the scales of the fish every day, and the color is naturally bright. This fish food is pure and natural, harmless to the fish, and the beautiful color of the fish on the stall is maintained by eating this fish food.

Dyeing can be done by feeding feed, but this is generally discouraged.

Make your fish beautiful by adding color to the feed.

The technique of dyeing goldfish is quite difficult, not as simple as that of cats and dogs.

There is an introduction to the fish net.

It can be dyed, but it can affect the life expectancy.

If you can't dye it, it will melt away in the water.

The colors of goldfish are red, orange, black, blue, silvery-white, etc.

In the process of development, some goldfish will have a fading phenomenon, such as black goldfish in the ink blister, etc., the color composition of goldfish is only three kinds of pigment cells, namely black, orange and light blue, these pigment cells recombine and distribute to form a variety of colors.

<> goldfish have a variety of colors, the common ones are black, red, blue, white, gray, yellow, purple, spotty, five flowers, transparent, etc., some varieties of goldfish in the process of ontogeny, there will be fading, black goldfish such as ink dragon, ink blisters and other varieties, the body color will change with age.

This ** is a goldfish, misleading, this is all artificially hit with a laser, and the specific method is not known. Such a fish is not in good health,

You fish, first of all, the fish food that has not yet been colored is expensive, don't think about the hair color, you are just playing, it is pure play, not to talk about raising, it is good not to die.

When you're done raising fish, you're thinking about hair color, and you're too advanced in this question, and you can't understand the answer.

Feed live food, generally the hair color is better, nematodes.

The main reasons for the discoloration of goldfish are:

1.Genetic factors: If the broodstock changes color early, the offspring will change color early, and vice versa, the offspring will change color later. This is why experienced fish farmers always keep goldfish that change color early as their parents, and environmental factors have a greater impact on the discoloration of broodstock.

2.Changes in water temperature can also cause goldfish to change color: under normal circumstances, when the water temperature is relatively high, the body color of goldfish changes quickly, and it takes 15-20 days to complete the entire color change process, but when the water temperature is relatively low, the process of color change will be slower, and it can be up to half a year undecided.

3.The fiber factor can also cause discoloration in goldfish: light passes through the goldfish's visual nerve centers, affecting its fading.

Goldfish raised in a low-light environment or in a black container will fade late and form a darker body color after fading, and vice versa, the color will fade early and quickly, and the body color after fading will also be light. Goldfish raised in clear water for a long time fade early, while goldfish raised in thick green water fade late, so the juvenile fish breeding process should increase light and improve water quality to promote goldfish to excel early.

4.Finally, nutrition is also an important cause of goldfish discoloration: experiments have shown that nutrition can also affect the fading of goldfish.

The juveniles that are often fed daphnia, mosquitoes, small shrimp and other animal bait fade quickly, and the body color is bright, while the juveniles fed with pellet feed, rice, noodles and other commercial feeds fade slowly, and the color formed is not as good as the former.

1. Goldfish are grass-colored in the juvenile stage, and the color gradually appears as they grow up;

2. The color of the goldfish has a lot to do with the sun, the fish tank and fish pond with better sunshine will have more vivid colors, and the color of the fish will be darker.

When I was young, it was black, and when I grew up, it became red. . .
