There is a question about goldfish eye 25

Goldfish eyes are generally treated because of long-term wearing of high glasses, so they can only be prevented and are not easy to treat.

Grape-eyed goldfish is a case of random evolutionary selection. It is not directly related to the physical characteristics of the parents. This does not necessarily mean that the offspring produced are also grape eyes.

Goldfish is one of the world's three famous ornamental fish, originating in China and has a history of more than 1,700 years.

Goldfish occupies a very important position in China's ornamental fish exports. Goldfish has a beautiful body and a wide variety of species, its body color is red, yellow, blue, purple, black, white, two-color, three-color, five-flower, etc., its body shape has lion head, high head, blister, dragon eye, pom-pom, pearl scales, butterfly tail, tiger head and so on.

Habits. Goldfish have a gentle temperament and generally live for about 6 years, but there are also longer ones. Goldfish is an omnivorous carnivorous freshwater fish with well-developed throat teeth that can swallow harder baits. Goldfish have a strong ability to adapt to water temperature, but can not adapt to the drastic changes in temperature, its suitable water temperature is 18-26, too high or too low will affect the feeding and growth and reproduction of goldfish.

Goldfish prefer weakly alkaline water, and the pH value of the water body is more suitable.

At the time of the transition of spring and summer in northern China, when the water temperature begins to rise, goldfish also enter the breeding period, and the water temperature during this period is controlled at about 20, which is more conducive to the spawning and hatching of goldfish.

Deterioration of the feeding environment or the addition of new fish that have not been quarantined, resulting in bacterial infection, local erythema on the body surface, redness, swelling and whitening of the eyes, and blindness.

Isolate severe and dead fish as soon as possible, usually with antibiotics, etc.** Cause Symptoms: Exophthalmos is only a cosmetic symptom.

In addition to the protruding eyes.

There will also be a white phenomenon.

In severe cases, the eyes may also fall out. But diseased fish with protruding eyes don't die right away.

Even after the eye falls out.

It can also survive. Generally speaking.

Ophthalmos often occurs in combination with ascites.

How to heal the exophthalmos.

At present, there is no good way to do it.

Antibiotics are commonly used.

Oral medicated baths are acceptable.

The method is the same as that of the treatment of ascites. Ascites and exophthalmos are mostly associated with deterioration of water quality and excess organic matter in the water.

Since there are difficulties in the application of the drug**.

It is also important to manage the aquatic environment well. Especially the aquarium with aquatic plants.

The efficiency of the filter should be strengthened.

It is important to reduce the dead spots in the water. **: Change one-half of the water and replace the filter media with a new one; Add 250 mg of chloramphenicol to 20 litres of water until symptoms disappear.

or commercially available brands of Sera antibacterial and anti-worm drugs, American sterilizer or fuscour antimicrobial. Causes Symptoms: One is the appearance of white cloudiness on the surface of the eyeball, which is caused by the deterioration of water quality.

The other is the phenomenon of albinism in or near the center of the eyeball, and even the growth of sullen white cotton wool. This is usually caused by unbalanced nutrition or bacterial infections caused by trauma to the eyes. **：

In the first case, the water in the fish tank should be replaced1 3 and kept at a constant level, and it will be healed after a few days. In the second category, it is necessary to use drugs**, with water-soluble penicillin or special agents to isolate the treatment, such as azoo, tetra, hagen, etc. Recovery from bacterial white eyeball is slow and may take 3-5 months to improve.

1. Fish tank environment

The poor environment in the goldfish tank is one of the main causes of goldfish eye dropping. Poor water quality is a big problem for pets to lose sight and drop their eyes. If the water in the tank is not clean enough or contains too much ammonia or nitrate, it can cause a loss of clarity in the eyes.

In addition, scratches or impacts from the cylinder port or background can also cause blindness or eye drops.

In addition, too high or too low water temperature can also cause goldfish eyes to fall off. At low temperatures, goldfish's metabolic rate decreases, and their body tissues also become stiff, resulting in exposed eyeballs. When the water temperature is too high, the eyes of the goldfish spring reed are also easy to atrophy.

2. Malnutrition

Malnutrition can be one of the causes of the sudden drop of the eyes of goldfish. When the ammonia and nitrate levels in the tank are too high, the goldfish's eyeballs can be damaged. In addition, factors such as nutrient deficiencies, lack of oxygen, and fluctuating pH levels may also affect the eyes of goldfish.

Especially during the gestation and peeling periods, the ability of goldfish to absorb nutrients and minerals will be greatly enhanced. If the food provided by the developer is insufficient or of poor quality, it will lead to the problem of goldfish eyeballs falling off.

3. Genetic problems

Genetics may also be one of the main causes of eye dropping in goldfish. The occurrence of genetic problems can be reduced by selecting excellent varieties for reproduction. However, the genetic instability of the reproductive organs of goldfish may lead to an increased risk of eyeball loss in some emerging species.

In addition, some breeds are more prone to eye drops than others. For example, breeds such as the Lion's Head have their eyes already soaked in water, and if they are properly cared for, they can easily go blind or drop their eyeballs.

4. External injury

External injuries can also be one of the causes of goldfish eye drops. Sharp objects such as aquatic weeds and stones, as well as other larger species of goldfish, can cause damage to the eyeballs of goldfish. It is recommended to clean the fish tank in the fish tank regularly and replace the furnishings in the fish tank to reduce the probability of eye damage caused by hard objects.

In conclusion, it is very important to keep the fish tank clean, hygienic, and nutritious, which can keep your pet fish away from eye drop problems.

Goldfish have sight and can see. However, its eyesight is not very good, and it often uses the lateral line to avoid reefs and find food.

Although fish belong to the lower vertebrates, the structure of their eyes is similar to that of the human eye. The difference is that the lens of the human eye is oblate and round, allowing you to see things in the distance; The lens of the fish's eye, on the other hand, is spherical in shape, and only close objects can be seen. All fish are short-sighted, and they rarely see objects up to 12 meters away, which is related to the fact that the curvature of their lenses cannot be changed.

Yes, that's what I mean, goldfish have bad eyesight and are born with great myopia.

Suppose you give a goldfish a little experiment and put glasses on it, do you think she can see objects 12 meters away?

Suppose you were given 5000-degree eyes, what would you say you could see??

It's just a little bit like being blind.

Dr. Yang Xiaonan replied: Usually what we call goldfish eyes refers more often to swollen bubble eyes. The so-called swollen eyelid refers to the appearance of a bulging and bloated entire upper eyelid or the whole area around the eyelid, which is often due to the appearance of a bloated eyelid area caused by the relative hypertrophy of some fatty soft tissues inside the eyelid, or due to some related factors such as myopia and hyperthyroidism.

In some people, the internal glandular tissue on the medial side of the supraorbital bone has a local downward sagation due to the presence of the supalathroplanar bone, resulting in a pronounced bloated and bulging appearance of the upper eyelid, especially the lateral side. Therefore, for these factors that can cause a very obvious bloated appearance of the eyelids, we can obtain a more ideal appearance for these so-called swollen and bubble eye corrections. The method includes the corresponding soft tissue through the surgical incision, the removal of the excess part, the retraction of the gland, and of course, some times, we will enlarge the volume of the orbital cavity and do some retraction of the eye contents, so as to obtain a better ** effect.

Many people think that goldfish have big eyes, and they must have good eyesight and can see objects very clearly. Actually, no, the eyes of the goldfish cannot see objects very clearly.

Although the eyes of goldfish are large and spherical, they are actually short-sighted. That is to say, a goldfish can only see objects or food that are very close to it, and for those objects that are far away from it, the goldfish can only see the shape of those objects very vaguely, but cannot see clearly.

Hello, I'm not a goldfish, I really don't know.
