If you put a goldfish in a dark room for a long time, why does the body surface of the goldfish fade

Goldfish have a variety of colors, unique red, some gold, some are also black and the like, that is, their color is still relatively bright, so long put the goldfish in a dark room will fade, this happens mainly by the influence of the clock, the first is affected by its light, all plants and all creatures need sunlight to grow,As for the surface of the goldfish, it needs the photosynthesis of light to achieve its bright color.

If it is placed in a dark place without sunlight, then it will gradually fade, the second reason is nutrients, goldfish will have some very good nutrients when they grow in nature, such as some microorganisms in the water or what they like to eatSo during the period when we are giving birth, it eats fish feed, which will not be conducive to the development of its body pigment.

In the process of raising goldfish, we often encounter the problem of goldfish fading. The goldfish I saw in the fish shop were red and bright, and they faded a lot less than a week after I bought them, and they didn't look like they were as rare as before. But it's a living thingwill continue to raise, and there is no longer the same enthusiasm as before.

Although goldfish look colorful, there are only three types of real body color cells: black, orange, and light blue reflective tissues. Then there is the completely discolored white, which is more or less made up of these combinations.

In the case of natural appropriateness, the body color of the goldfish is also constantly changingWhen I was a child, all goldfish were blue-black and did not begin to change color until a few months later.

The color of the little goldfish we raise at home is formed by the joint action of various pigment cells. Their ancestors were crucian carp and, like most freshwater fish, did not have too bright colors to survive more safely. Only occasionally a few body colors mutated into red and yellow were discovered by the Chinese, who thought that they were auspicious, so they specially bred them in captivity so that the colors could be preserved.

Because goldfish adapt to changes in the environment to protect themselves from being detected by predators.

No matter what kind of organism it is, it needs photosynthesis. As soon as you get out of the sun, your body changes. Therefore, if you put the goldfish in a dark room for a long time, the surface of the goldfish will fade.

Not only goldfish, but also people, if a person lives in the dark for a long time, he must be pale.

Because goldfish, like plants, also need sunlight and need to maintain their own color, if there is no sunlight for a long time, it will slowly fade to a light color.

Keeping goldfish in a dark room for a long time changes their sensitivity to light, so the color of the body surface slowly fades, and white fish appear in some places, and it is for this reason.

Summary. b. Dissolve malachite green grams or methylene blue in 100 kg of water, soak the fish body for 10 20 minutes, and the mycelium can be seen to fall off after a few days.

The goldfish turned black but were active.

Hello, I'm glad to answer for you, goldfish have black spot disease, the pathogen is mainly water mold and mold, parasitic on the wounds and eggs of the fish body, is a more common fish disease. **Mainly the fish body is injured, the scales fall off, etc., resulting in the invasion of germs into the wound.

**Method a: Sprinkle 250 grams of salt and 250 grams of baking soda mixture on a 100cmx55cmx45cm fish tank, insist on several times, and the effect is remarkable.

b. Dissolve malachite green grams or methylene blue in 100 kg of water, soak the fish body for 10 20 minutes, and the mycelium can be seen to fall off after a few days.

c. Soak in 2%-3% salt water, once a day, for 5-10 minutes each time.

d. Mix 2 parts per million (2ppm) potassium permanganate plus 1% brine and soak the diseased fish for 20-30 minutes.

e. Increase the water temperature to inhibit the growth of water mold. And a 15-watt ultraviolet lamp can be used to irradiate for several hours a day, which can effectively inhibit and eliminate water mold.

It's caused by the low water temperature.

Hello, it is caused by water quality and has little to do with water temperature

Slowly lighten it.

Because goldfish are kept in a dark room, the room basically cannot accept light, so the physique of the goldfish will change, and the color will slowly turn white. Some people who have not been exposed to the sun for a long time are significantly whiter than normal because of the lack of ultraviolet radiation.

The environment in which goldfish are raised

The fish tank is the home of the goldfish and is where they live, so it is very important to choose the right fish tank. Goldfish will not grow very large, but generally there are more than several goldfish, so don't choose too small fish tank, which will make the fish appear crowded and easy to die of lack of oxygen. So according to your plan to raise a few fish, then choose a fish tank, and choose a slightly larger one.

The fish tank has just been bought, you can add a small amount of yogurt and beer to the empty tank, and then put small goldfish when the brown algae disappears and grows green algae, which can be said to be "natural" growth, and the goldfish has been kept indoors, and the outdoor green algae is mixed with many other bacteria, which is not conducive to the health of the goldfish.

You can also put some aquatic plants, rockeries, and stones in the fish tank to create a relatively fresh environment. Aquatic plants can purify the water and provide some oxygen, and rockery stones give them a place to play. If conditions permit, you can also buy a heating rod, the goldfish will live more comfortably, and a constant water temperature is also important for the overall survival rate of the goldfish.

The darkening of the goldfish may be due to the deterioration of the water quality.

When the water quality is poor, or there is pollution, the water can contain a large number of toxins, which will cause goldfish lesions, malignant transformation and cause cancer, and turn black. If this is the case, the water for fish farming needs to be replaced in time. In addition, when a goldfish gives birth while pregnant, it is normal for local areas to turn black.

Originating in China, goldfish is also known as "golden crucian carp", which resembles carp but has no mouth whiskers, and is an ornamental fish that evolved from crucian carp. There are many varieties of goldfish, the colors are red, orange, purple, blue, ink, silver-white, five-flower, etc., which are divided into four categories: 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.

When the body of the fish is weakly digested, the goldfish will turn black when it is cold, which is a stress response, and it will slowly recover after the weather is warm.

The reason why small goldfish turn black is mainly controlled by the genetics of the goldfish itself. The basic color of the goldfish will gradually change as the body develops, and it will change color several times during its lifetime. Some of the following factors contribute to the discoloration of goldfish:

1.The water temperature is high and the discoloration is the fastest. The water temperature changes greatly, and the discoloration slows down.

If the water temperature exceeds 30 for a long time, the goldfish will lose their luster. 2.Alkaline or acidic water will darken the color of goldfish.

3.Light directly affects the change of the body color of the fry, the color of the goldfish will turn white when direct sunlight is exposed, and it will turn black if there is too little light. 4.

With more animal baits, goldfish change color very quickly and shine brightly.

In general, there are two reasons for the fading of goldfish, one is the genetic cause of the goldfish itself, and the other is the influence of the acquired breeding environment. From birth to old age and death, the color of the goldfish's body is changing, from juvenile to prime, the color gradually brightens, and the color will dim after old age. Moreover, the usual light, nutrition, water temperature, etc. will affect the body surface color of goldfish.

The fading of goldfish is a natural condition in itself, and the color of the goldfish from birth to prime age will become more and more gorgeous, and the color will become dull after old age, which is a very natural phenomenon. In addition, goldfish will also fade due to insufficient sunlight during feeding, low or high water temperature, malnutrition, and insufficient oxygen in the water.

Prevents goldfish from fading

1. To prevent goldfish from fading, proper light is very important, which can increase the body color cells of goldfish, so that the color is more gorgeous.

2. The water temperature can not be too low or too high, the most suitable water temperature for the growth of goldfish is 22-24, the fastest water temperature for discoloration is 28-30, and the water temperature can be appropriately fed to increase the body color when the water temperature is high in summer.

3. When the amount of dissolved oxygen in the water is greater than 3 mg per liter, the goldfish color is fast, and when the amount of dissolved oxygen is less than 1 mg per liter, it is easy to fade.

4. Pay attention to the nutritional combination of feeding, malnourished goldfish are easy to fade.

5. Use color-enhancing lights, the use of color-enhancing lights can make goldfish look more beautiful, which is why many people buy goldfish from the market and find that the color is not as good as when they bought it.

6. Feed color-enhancing feed, regularly feed goldfish some color-enhancing feed containing zeaxanthin and carotene can also make the goldfish more colorful and avoid fading.

Black goldfish turn golden because black is the fetal color of goldfish, which fades to gold over time. As long as the ambient temperature is sufficient, the food is sufficient, and the oxygen is sufficient, the fading will occur, and the fading time will last for three to four months. Goldfish fading is also a sign of proper management by keepers.

Black goldfish turn golden because goldfish usually hatch from eggs with a cyan fetus, and the fetal color slowly fades over time. However, the fading time is early and late, which is affected by environmental factors.

Black goldfish will fade to gold at the age of five to eight months if the environment is warm enough, food is sufficient, and oxygen is sufficient. Fading lasts for three to four months, depending on environmental factors.

The black goldfish turns golden, which is also a manifestation of the goldfish's comfortable life. When the black goldfish feels safe, the black protective color will fade, which also means that the keeper has managed the goldfish well.
