What s the deal with fishtail atrophy? What s going on with the crooked tail of the koi fish

This is a little goldfish suffering from urgency, caused by improper water change.

When the water temperature of the water body, the pH value.

When the hardness changes too much, the fish will shrink into a ball, and if not handled properly, it will often lead to mixed infection with other pathogens.

Treatment methods should focus on prevention, taking care that water quality and water temperature do not change too much. When adding new water, pay attention to mixing slowly with the old water to allow the fish to gradually adapt to the new water. When fish diseases occur, pay attention to maintaining stable water quality.

If the water quality is poor, it should be replaced with suitable water in large quantities, and drugs should be used to control the pathogen if necessary.

Infect. Fin.

The damage is discolored and dull, and there is a foreign body in the rotten area, or the transparent fin leaves are whitish, and the white gradually expands. In severe cases, the fins are mutilated and adherent. The disease is mostly prevalent in spring and summer. Salt and antibiotics can be used**.

This is a typical tail clamping disease, or a precursor to a bad tail. You can try this method. **：

Fasting for 4 5 days, the whole box of antibiotic drug penicillin: 90 45 60 (centi) box 800,000 units, 1 in the morning and 1 in the afternoon, for 3 consecutive days as a course of treatment. Generally 4 to 5 days can be **.

There are two reasons for the twisted tail of koi fish, one is a natural defect, and the other is caused by bacterial or parasitic diseases that invade the koi nervous system. The first reason is not legal, and the second reason is still possible, but the method is still relatively professional, mainly based on drug injection, and even then the possibility of complete ** is very small. I encountered it once in my own year and it ended in failure, and then a friend's koi also had this situation, and I cured it.

However, the reason for the success and failure was later summarized as the better and bigger the fish, the greater the likelihood of **, I only had 35 koi that died at that time, and 65 koi that were cured later.

Responsibly tell you that the tail of the koi fish is not bai

Deformed. du

If there is a change in the fish must be a red small crucian carp zhi, now dao a lot of traders use red small crucian carp to pretend to be koi **, there is no virtue. It is normal for fish to not move and eat at the turn of winter and spring. So:

One, your fish must be red, or red and white (because it's crucian carp). Two, your fish is not sick. Third, your fish will turn white if its tail is inflamed, and koi fish also have red and white, but a fish, especially a small fish, can produce this color, and you can't buy it for a few hundred dollars.

Koi fish have whiskers on their mouths, but golden crucian carp do not, so they are easy to identify.

Rotten tail, melted tail, burned tail. Most of the reason is that there is a problem with the water quality.

It is possible that Bai has bacterial rotten tail and rotten fins. du

Water quality problems, resulting from deterioration of water quality.

The fish got enteritis.

The fish swim fast, often collide with the fish, and are very easy to get injured.

If the water is not changed in time, bacteria can grow.

The ecological environment is poor.

Fish shapes: spindle-shaped, side-flattened, flattened, club-shaped.

Fish bones are divided into two categories, cartilage and hard bones, according to their nature. Cartilaginous fish maintain cartilage throughout their lives, and the calcified cartilage is also called calcified cartilage due to the calcareous sediment in the soft matter. The bones of bony fish are mainly hard bones, which are divided into two types: soft hard bones and periosteum according to different forms

The hard bone formed by ossification on the primordida of cartilage is the softening of hard bone, such as vertebrae, ear bone, occipital bone, etc.; Hard bones formed by direct ossification of the dermis and connective tissue are called membranous bones, such as frontal bones, parietal bones, operculums, etc. The bones of fish are divided into two parts: axial skeleton and appendicular skeleton according to different parts.

The efficacy of fish: autumn and winter are a good time for the weak to take supplements, and fish is a good aquatic food for tonic, which is not only delicious, but also has high nutritional value. Its protein content is twice that of pork, and it is a high-quality protein with a high absorption rate in the human body.

Fish is rich in thiamine, riboflavin, niacin, vitamin D and a certain amount of calcium, phosphorus, iron and other minerals. Although the fat content of fish meat is low, the fatty acids in it have been proven to lower blood sugar, protect the heart and prevent cancer. Vitamin D, calcium, and phosphorus in fish are effective in preventing osteoporosis.

The benefits of eating fish: brain strength, heart protection and lipid reduction, efficient calcium supplementation, blood nourishment, anti-diabetes and hypertension, anti-oxidation, anti-distortion.

You may have bacterial rot and rotten fins. **Method: Bacterial rotten, rotten:

Tail rot and rotten fin disease caused by bacteria are highly contagious, starting with the fin bars and then decaying to death. There are two symptoms of this type of rot fin disease, the first one starts to rot at the edge of the fin and then extends inward, and the second one starts from the fin ** part and spreads in all directions. The affected area turns white and eventually falls off.

Goldfish are most susceptible to the disease when their body becomes less resistant after transportation or spawning. Once the diseased fish is found, it must be isolated immediately and treated with antibiotics or drugs such as dingline yellow to ** the diseased fish. When the symptoms of rot appear slowly, the best way to do this is to replace part of the tank water, clean the filter and add a little salt to the tank, and stop feeding for a few days.

Table salt** works by increasing the specific gravity of water, changing the osmotic pressure in the water, and killing bacteria and other pathogens through the change in osmosis. You can also directly use the commercially available Sera Antibacterial Anti-Insect Anti-Insect Agent, American Sterilizer, Queen Whale Anti-Bacterial Anti-Goldfish Disease Anti-Agent, Queen Whale Anti-bacterial Anti-Bacterial Agent and AZ00 Anti-bacterial Agent**. The water quality problem is a big problem for goldfish to get sick, because goldfish have a certain range of adaptation to the physical and chemical properties of the water body.

If you don't get used to it, you will have problems.

Water quality problems should be divided into two situations, one is the deterioration of water quality; The second is that the water is too new and too raw.

If the density of fish per unit of water is large, resulting in a poor ecological environment, coupled with the lack of timely water change, the excrement and secretion of the fish are excessive, carbon dioxide and ammonia nitrogen increase, microorganisms breed in the water, various algae grow too much, the water quality becomes mixed and deteriorated, and the amount of dissolved oxygen decreases, resulting in the deterioration of water quality. Like some bacterial diseases, it is more likely to flare up at this time. Goldfish may have dark spots, inflamed erythema, gill disease, bloodshots, blindfolds, and even if the fish are pumped, their heads will float.

If it is not improved, it will soon incur the death of the goldfish. Therefore, there are two points to control water quality, one is to control the density, and the other is to strengthen the filtration system.

If the water is too raw and too new, the damage to the goldfish is worse than the deterioration of the water. Therefore, it is important to pay attention when changing the water or opening the cylinder. When changing the water, it is best to keep part of the original tank water (do not use the sick water in the whole tank).

When opening the cylinder, it is best to add some bottom sand, filter material, and old water used by others to the new cylinder. At the same time, it is necessary to strengthen the pumping, so that the water quickly becomes an environment that the goldfish can adapt to, the longer the better, and it is often fatal for the goldfish to rush too quickly.

If the tank is not well raised, the koi eat a lot, the water quality is easy to deteriorate, and it needs a lot of filtration. The water deteriorates and bacteria grow. Goldfish must not live long.

Hello, there are generally two reasons for koi fish shrinking fin tank: water quality ** change; Ectoparasites. The first thing you have to do is find out what is the reason for the shrinking of the fins.

Koi fish must be raised in a bare tank, and if you want to look good, you can pave a layer of rain stone at most, which is easy to clean, conducive to the maintenance of water bodies and can also prevent external injuries.

Fish farming must be water, and fish health must also have strong filtration, clean and stable water. If the water quality deteriorates, it is necessary to disinfect and change the water in time, if the water body is fine, it is a parasite, go to the fish market to buy some trichlorfon (pay attention to the dosage).

Considering that your fish has a rotten tail and shrinks its fins, I suspect that the water quality is not good, so let's change the water first. Tap water can only be used after two or three days or three or four hours in the sun! The fish tank is wiped and disinfected with potassium permanganate, and then the water is changed.

Then the koi fish have to be disinfected and anti-inflammatory, you prepare a basin, put a few grains of potassium permanganate (pharmacies sell a bottle for one yuan), the water can be dark purple, do not turn black purple, the fish can't stand it. Then put all the koi fish into the pot for about 15 minutes to soak and disinfect, do not leave the person during the whole process, and if you find that the fish is seriously unwell, you should immediately remove it.

Wrap the fish's body in a clean towel to prevent struggling, soak a few cotton balls and wipe with a high concentration of potassium permanganate to press the damaged fish (be careful not to drip into the fish's mouth or gills). After treating the wound, put it back into the basin for a minute or two, and then remove it and put it in the fish tank (the wound should be stained purple). After that, the sick fish will be disinfected every two days, and it will get better soon.

My koi fish have rotten fins and tails, traumatic infections, and gill piercings are all good with potassium permanganate**.

Raising koi fish is actually very simple, the water body remains stable, and people are diligent and the fish do not get sick.

It should be goldfish bacterial rotten fin rot tail disease.

First, it is mainly the result of the combined action of the pathogens columnar myxococcus and mold. The infection is carried out by two ways, one is because the breeding density is too large, the filtration function is not ideal, and the metabolic waste of the fish accumulates, which triggers the explosion of germs and infects the fish. Second, because when a new fish enters or the water is changed, the water quality difference or tension shines on the fish body discomfort, so that the surface mucosa secretion is abnormal, and the edge of the fin and tail is infected because of weakness.

2. Symptoms of goldfish rotten fin rotten tail disease: fin scales fall off, inflammation, muscle necrosis, rot, hyperemia at the base of the fin, three opening of the fin into the shape of a broom, and the entire tail fin rot in severe cases. Diseased fish have normal scales, and individual scales will fall off.

3. The best method of goldfish rotten fin and tail: In fact, goldfish rotten fin and tail disease and golden** inflammatory congestion disease are roughly the same.

1. You can choose 1% malachite green aqueous solution to be applied to the place where the tail fin is broken, once a day, for 3-5 days, and combined with the method of inflammatory congestion.

2. If part of the fin is rotten and incomplete, it should be cut off with scissors to make the tail fin flat, and then treated with method 1, after a period of time, the tail fin fin can be healed, and a trace will be left between the regenerated fin and the old fin bar, although the ornamental value is reduced.

3. Put nitrofuracillin powder in 100 kg of water for soaking and disinfection, and the condition can be relieved after repeated medication.

4. Put 3-5 tablets of dysentery in 100 kg of water, and soak the diseased fish for 30 minutes.

5. Put oxytetracycline 5-8 tablets in 100 kg of water for washing and disinfection to prevent infection with this disease.

It's usually bacterial rotten fins or bites from other fish.

Yellow powder can be added to 1% concentration of salt for continuous medicated bath for 2 days to maintain water quality.

That's a common disease, fill a washbasin with water, put (a little) of edible salt in it, let the fish swim in it for a few minutes every day, and it will be fine after 2 days.

Go to the goldfish shop and buy medicine to make a bubble.

White spot disease, also known as melon worm disease, is a common fish parasitic disease, to the water body to warm up to 30 degrees, generally about a week can be **, keep changing the water every day, you can also put a lot of salt in the whole tank, change the water every other day, there are also white spots on the market.

This is white spot disease, which is caused by excessive changes in water temperature, first warm up, take a methylene blue medicated bath for 30 minutes, or buy drugs such as white spot net.
