What s going on with the goldfish turning black, what s going on with the goldfish getting black

There may be several reasons for the black color of a goldfish's body. The first is that the goldfish has been in the poor water quality environment for a long time, and its body has lesions, which may grow some diseased tissues, or it may be in the relatively poor water quality, resulting in purulent foci, and then the body is blackened and suppurated. The second is that the goldfish may be spawning during pregnancy, and the spawning area is getting darker and darker, which is normal.

If the goldfish has pathological dark spots, it is recommended to change the water immediately and then take an antibiotic bath, which generally improves in about seven days. It is also necessary to change the water frequently and clean the fish tank. If the goldfish you just bought is black, it may be that the goldfish is not adapted to the new environment, and generally speaking, it will get better in two to three days.

It is also important to note that if you feed too much fish feed to a goldfish, you will also find that the goldfish's body turns black, which is due to eating too much fish feed. There are some goldfish whose bodies look transparent and appear blackened, which means that they have eaten too much.

10. What is the reason why the scales of goldfish turn black and have black rust?

If the goldfish body turns black, then it may be black spot disease, which is mainly caused by poor water quality, and it will be very serious if it is not treated in time. First of all, the water in the fish tank should be replaced, and then edible salt, baking soda, methyl blue and other substances should be added to the water to help the goldfish recover their health. The body of the goldfish gradually turns black, generally because the water source has not been changed for a long time, so that the water quality produces a large number of bacteria, causing the goldfish to suffer from black spot disease, if not treated in time, it may also make the goldfish body injured, scales fall off and other symptoms.

** The method is to pour a small amount of salt and baking soda into the fish tank, these mixtures can kill some bacteria in the water, and be careful not to damage the goldfish when changing the water.

Food poisoning can also cause blackening on the goldfish's body, if it is caused by food poisoning, then change the goldfish with clean water, clean the fish tank at the same time, temporarily stop feeding, and rest for 2-3 days.

Blackening on the goldfish can be restored.

The blackening of goldfish is usually due to a stress response caused by environmental changes, and usually the goldfish that have just been bought are put in the water for a period of rest to recuperate, and their bodies can regain their luster. Don't change the water and feed the goldfish for three days, let them get used to the water first, and then start feeding when they feel well.

How to raise goldfish

1. Water temperature: Goldfish are temperature variant animals, and their adaptability is relatively strong. Normally, they can grow in water temperatures between 0 and 38.

When farming, it is best to keep the water temperature between 18 and 25. In this temperature range, they are best at what state they grow in, as well as how fast they grow.

2. Water quality: Goldfish can adapt to a wide range of water quality, and they can live in weak acid, weak alkali and neutral water. However, they prefer the slightly alkaline water, and it is best to keep the pH between them if they can.

In addition, before changing the water, the keeper should also dry the water for a few days to avoid chlorine affecting the health of the goldfish.

3. Food: The diet of goldfish is relatively mixed, and the breeder can choose to feed it with animal feed and plant feed. This not only ensures that they live with adequate nutrition, but also ensures that they are nutritionally balanced.

Precautions for goldfish rearing

1. Stable environment: Although goldfish have strong adaptability to the environment, they are sensitive to fluctuations in the environment. Breeders need to keep the environment in which they live stable so that they can grow better.

2. Reasonable feeding: Goldfish do not have a sense of satiety, and it is best for the keeper to feed them regularly and quantitatively. Juvenile goldfish need to be fed twice a day, and the amount of each feeding can be eaten within 5 minutes.

Adult goldfish can be fed once a day, and the amount of each feeding can be eaten within 10 minutes.

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.

Trauma, goldfish injury may be caused by trauma, after the discovery of the need to change the water in time, and into the coarse salt for **; After being frightened, the body surface of the goldfish is also easy to turn black after being frightened, and it is necessary to ensure a stable environment in the later stage to let it recover as soon as possible; Black spot disease, goldfish are also prone to black spot after suffering from black spot disease, and the diseased bait needs to be isolated and raised, and potassium permanganate solution is used for medicated bath**.

The blackening of the goldfish's body may be caused by the lack of timely trauma, and the goldfish's body surface is fragile and very prone to injury. In addition, if the feeding density is too large, there is also a tendency for goldfish to fight and get injured. After discovery, it is necessary to change the water in time, and put an appropriate amount of coarse salt into the tank to inhibit the growth of bacteria, and if the infection is more serious, apply ointment**.

Goldfish themselves have a short temperament, and after being frightened, the body surface is prone to blackening. If someone paces back and forth around the tank or slaps the walls of the tank, the goldfish will be frightened and cause the body color to turn black. After discovery, it is necessary to ensure that the surrounding environment is stable and allow it to recover as soon as possible.

During this period, bloodworms, earthworms and colour-enhancing feeds should be fed to keep them in good body color.

The blackening of the goldfish's body surface may also be caused by black spot disease, which is mostly caused by bacterial infection, and after the disease, the goldfish will appear with patches of black spots. Sick fish need to be isolated and reared in time to avoid infection to other healthy fish, and then potassium permanganate solution can be used for medicinal baths, soaked for 30 minutes a day, **2 3 days later, the condition will improve.

Causes of blackening in goldfish:

1. The water quality is not good, when the water quality in the fish tank is not good, it may cause the goldfish to be infected with germs and get sick, so that the body will turn black.

2. Poisoning, when goldfish ingest harmful substances, it may also cause the color to turn black, so it is necessary to detoxify the goldfish as soon as possible**.

3. Scale-hardening disease, when goldfish are infected with scale-building, they will also have symptoms of blackening on their bodies, so they need to isolate, anti-inflammatory, sterilization, etc.

3.Rotariasis (melanosis). The symptoms of this disease are that the sick fish are emaciated, dull in color, and the lesions in the gills cause breathing difficulties and swim on the surface of the water.

Caused by the parasite of the wheel worm in the ** or gill region, the water temperature is above 25 May and August is the epidemic period. If it is black body disease, it is recommended to use 1 salt water for feeding; Twenty parts per million potassium permanganate solution in a medicated bath for 10-20 minutes.
