There are cases of rotten tails in marine fish, but the appetite is not bad, what to do

In the case of rotten tails of marine fish, the following steps are generally followed:

1.Segregated feeding: If you find that the tail of a fish is rotten, you must isolate it, because the rotten tail is the most vulnerable to attack by other fish, which will not only not get better, but the situation will worsen.

Moreover, the unfinished tail is generally caused by fungi, and it is also helpful to its condition when it is separated from the original water environment.

2.The old three: If the tail of the fish is rotten, the initial ** means is the old three.

Change the water first, improve some water quality, and also remove some mold from the water. Secondly, it is necessary to raise the temperature appropriately, and the temperature rise is very helpful to the fish. After heating, salt needs to be added, and the general concentration is 3 or 5 thousandths, which can have the best effect.

The most common drug is yellow powder, that is, nitrofuracilin, put 100 grams of water in grams, and then soak the fish **, not too long.

The temperature of the fish tank can gradually increase by 1-2, and you can choose to use gramfuracillin powder (commonly known as: yellow powder), dissolve in 10 kg of water, and soak the diseased fish for 10 minutes. You can also choose furazolidone 3 5 tablets, dissolved in 100 kg of water, soaked in the aquarium *** autumn water fish Yue culture spread to wash the sick fish for 20 30 minutes.

Or choose oxytetracycline 5 8 tablets, dissolve in 100 kg of water, and soak the diseased fish for 30 minutes.

Two situations: 1. The nitrite content of the water body is too high, and the chronic poisoning causes the decline of fish physique.

2. The difference between the physical and chemical indicators of water change and raw water is too large, and the fish is seriously unadaptable.

In the first case, the filtration system is strengthened and nitrifying bacteria are added. If it is the second case mentioned above, then do not change the water too often, or the water change treatment is more detailed. The causes of the same symptoms may be two opposite causes, so it is important to distinguish between them.

When the tropical fish is rotten tail, we must first isolate the sick fish, and then change the water, which can be like sprinkling salt in the tank, which can play a role in sterilization.

This can happen if the injury is not disinfected in time.

The causes and solutions for rotten tails in tropical fish are as follows:

1. The aging of water quality causes a large number of bacteria. For example, you have not changed the water for many days due to busy work, or you have something to do and are away from home for a few days, and when you come back, you find that individual fish have shown symptoms of rotten tails or rotten fins.

2. Infection with bacteria after being bitten. Due to improper polyculture, the tail is bitten by other fish, which continues to lead to rotten tails. In this case, the water quality is generally not poor, so it is found and isolated in time, and the rate is relatively high.

3. Sudden temperature changes. Due to the change in temperature or the large temperature difference when changing the water, the fish catch a cold and lose their resistance, and the tropical fish with the most gorgeous tail will lose the protection of the mucus from the tail and cause the tail to rot. This condition can lead to death in a relatively short period of time, with the highest mortality rate.

4. Hot tail disease caused by bubble disease. High temperatures are common in summer (water plants and greenish water that does not change the water), and it is most likely to be caused by goldfish. In summer, the sun shines, so that the water temperature in the pool (tank) is high, the photosynthesis of algae and aquatic plants in the water is vigorous, so that the dissolved oxygen in the water is saturated, then bubbles will be produced, and the fish will stick to the tail in the process of swimming, so that the fish will lose balance and "head and tail" float on the water surface, and then be irradiated by the sun, resulting in the tail fin tissue being burned.

**: The water body of the fish tank is narrow, the fish are crowded, there are many residual bait, and the water is not changed frequently, so a large number of water molds are breeding and causing diseases.

Susceptible fish age: fry within 10 days of age, 1 or 2 months old in tanks. Adults are less likely to be infected.

**: Use Haibao brand water mold clean, and follow the instructions. Or use sea salt**, sprinkle the whole tank with saturated brine (add one milliliter of saturated brine per liter of feeding water. Increase the water temperature to 28-30 degrees. If necessary, yellow powder can also be applied to prevent secondary bacterial infections.

It should be added that in addition to water mold infections, there are several bacterial infections that can also cause clipping:

1. Adhesion: the tail angle is reduced, the swing is abnormal, the whole tail seems to be coated with a layer of paste and then dried, in addition to not being opened, it also becomes more "hard", some fish soon tend to be exhausted, and the head and tail are erected in the water and slowly sinking, which is a bacterial disease, and the drug of bacterial disease should be used.

2. Dissolution of the edge of the tail fin: the edge of the tail fin seems to have been scalded by boiling water, dissolved, the edge is puffed up and loosened, and it is milky white. Bacteriological drugs should also be used for this condition**.

3. Mixed infection: refers to the mixed infection of bacterial disease and water mold disease, at this time, only according to the method of water mold disease, there is no effect, and it will even be more serious, so the correct diagnosis is also very important, and mixed drugs can be used for mixed infection.

**: Poor water quality, untimely water change, and rapid pH changes may be caused.

I or my family have tropical fish, and what is the reason why its tail hits the willows.

This phenomenon is more common for this type of tropical fish, and it can be called "fin-shrinking", and the reasons for this can be basically divided into two types:

It is more common for fish to be transferred to water or moved to tank, because the fish has not fully adapted to the new environment (including water quality, light, temperature, etc.).

1. Solution: This situation is relatively easy to deal with, do not use drugs easily, appropriately increase the temperature in the aquarium, put 3% of the salt if possible, observe for a few days (try not to feed during the period, and maintain good water quality, this is the premise), and can generally return to normal.

If the fin shrinks persists for a long time, it is most likely that the fish is already sick, and usually there are many kinds of diseases in tropical fish (most of the spines are caused by bacteria or parasites), similar to the symptoms of fin shrinking.

2. Solution: It is recommended to do a quarantine, if there are no obvious parasites on the surface of the fish body with the naked eye, it is mostly an endoparasite or intestinal inflammation (enteritis), you can use the human medicine fooperanic acid and metronidazole for medicinal bathing, rather less than more when using medicine, the interval between water changes after a large amount of medication can not exceed 3 days, and a small amount of medicine can be replenished when changing the water.

**: The water body of the fish tank is narrow, the fish are crowded, there are many residual bait, and the water is not changed frequently, so a large amount of water mold liquid is used to slow down the disease. It is also possible that there is a problem due to the wrong polyculture, for example, some fish like to bite the tail of their killer fish.

Good luck with your fish farming!
