Questions about koi fish, help!

Looks like I bought sick fish. The white hair may be water mold, the stomach is a little rotten and the scales are lost may be an infection caused by trauma, and the gill cover is red and you can see the gills inside, which is gill disease - "open the skylight"; Rotten tail and long white spots, perhaps rotten fins and white spots. After reading these, it seems that the common diseases of koi fish have been encountered by you at one time!

Sweat! It is recommended that you release all these fish and disinfect the entire tank thoroughly: soak them in potassium permanganate solution for 24 hours until the concentration of the solution is purple-black. Then let it dry.

Then it's time to raise the water. There are slow water nourishing and fast water raising. It's not too late to get fish in after the water is raised.

Slow water rearing: Buy a few solid fish into the tank, and after 4 weeks if you don't get sick and don't die, you're fine.

Fast water raising: throw a dead fish without disease into it, and then put EM bacteria, and wait for the fish to decompose.

After the water is raised, the new fish should be disinfected when they are bought: soak in 3% salt water for 2-3 minutes. If possible, it is necessary to isolate and observe in the quarantine tank for a period of time.

Fish farming must be explored slowly in order to raise it well, and dead fish should pay tuition fees if they are deceived by fish merchants. If you go to the ornamental fish forum more to learn, you will take fewer detours.

If it is white hair, it is water mold, and the fish body rubs the tank in the early stage and then the fish body grows white cilia-like substance, which is a fungal invasion.

Medication; 2 grams of cubic meters of methyl blue medicated bath.

Generally, you only need to feed once a day, not too much, and you say that your fish is dead. I recommend washing the fish tank from scratch.

Put coarse salt, put three fine particles.

It is difficult to save in the later stage, and it is necessary to disinfect it in advance, 2 thousandths of potassium permanganate.

It's definitely poisoning, but it's not like chlorine poisoning, which makes the fish jump out of the tank and have convulsions.

Difficulty breathing, opening the mouth and cheeks are more like symptoms of nitrite poisoning.

See what color is inside the gills of fish?

Purplish-red is chlorine poisoning, and reddish-brown is nitrite poisoning.

Nitrite poisoning is caused by not getting enough water.

Five hundred to six hundred and one of these ** can buy good imported seedlings in the fishing grounds in Guangzhou At most, no more than 15 to 20cm If it is big, it is extremely suspicious that it is a home-made fake The color of imported fish is the most gorgeous Because of high standards Not only does it require a pattern, but the color is also a high standard Basically, it is red as blood, white as snow, black as ink, and the price of self-produced is generally about 30cm, but I don't know how long you have raised it It is recommended not to buy such a good first time, and it is recommended not to buy such a good A few dollars a piece of first buy a batch of it The growth of novices is based on mountains of dead fish piles, but some dazed novices are to give him a year of dead fish, don't want to die out of a so, raise koi fish is suitable for fish ponds or ground tanks, ordinary finished tanks are not suitable for koi because under the right conditions, 2 years, a fish can be 30 to 40cm, 3 years can be 50 to 60cm, and then it will be slow, fish ponds need to be filtered, drained, and sewage, otherwise it is a stagnant pool, fast is half a year, slow is a year, absolutely dead bare, the tank needs to be designed reasonably, and the filtration capacity is sufficient Generally, few fish tank masters will do Beijing, Guangdong can be found in other places can not be found in other places can not be able to engage in the tank pool, then you can only buy the bottom filter fish tank That is in addition to the pool Tank is the most suitable for koi fish The size is required The length is not less than meters and the width is not less than 50cm This is the limit No matter how small it is, it is recommended that you still play goldfish or tropical fish. Koi fish need a large body of water and large filtration. Raising fish is a tiring job, you can't be lazy, and being lazy means dead fish.

The most important thing is that you have practical experience with fish diseases? Dead fish not only die due to illness but also die due to medicine For the control of the dosage of medicine, everyone has different methods and ways And the new fish to the home is also to be operated by the water If you don't do it well, 10 fish and 9 will die If you have the time, energy and financial resources, you can play It is the happiest to look at your own fish Novices recommend going to the koi forum to learn first Just at present, the fish in the fishing ground should go to the soil pond for the winter to prepare for the next year's breeding time You can't buy it The new fish should be on the market in the summer The time to go to the forum to learn during this time Go through the water, raise the water, recognize the disease, and take medicine!

You can go to the first koi network forum above There are many koi shops and choose the one you like.

I remember that there was a Beijing Jinhong Koi and Tokugawa Koi on the first koi forum, and the fish of these two companies are good, you won't go to see that?

Do koi fish also have dark spots? It's not a good thing to be sick. In our daily life, when we raise koi, we will suddenly find that there will be black spots on the body of good fish, which seriously affects the beauty of koi.

There are also various theories on the Internet, and some say yes"Melanoma . The pathogens are mainly water molds and molds, which are infected by the invasion of mold spores. But this phenomenon should not be called a disease, because it has no effect on the growth of fish, but is still a good sign.

First of all, it is necessary to know what causes dark spots to appear on the body of koi fish during the feeding process. Let's start with the trauma, some koi fish appear to have a black part of the body after returning home for a few days. Part of the reason is that during transportation, due to the collision and friction between the fish and the fish, the fish body is bruised, but there is no infection, and it heals after a few days at home, and the black plaque can be simply understood as a scab on the wound, that is, the fish was not found when it was injured, and it was found when it healed, so don't care, it's not a disease, even if it's a disease, it's going to be better.

Secondly, when we use potassium permanganate for daily quarantine, if potassium permanganate falls on the body of the fish, or the concentration of potassium permanganate is high, the surface of the fish will be damaged, and black spots will also appear when healing. There are also problems with water quality, the water temperature is too low, etc., etc., as long as the surface of the fish is damaged, dark spots will appear when healing. If you find that the koi have black spots, it means that the fish has some damage when you are not paying attention, but it is now in the stage of healing, and after a period of time, the water quality will be good and the black color will soon fall.

Black spot disease (black spots on koi fish, Piljuxin burrow fluke, also thought to be Piju bicus fluke and other species).

1.Signs of infection.

Small black or brown spots, up to 2 mm wide, appear on the body and fins, and sometimes on the eyes and mouth.

2.Infection in detail.

Spots are cysts containing larval intestinal flukes, such as Pyrocatodes piscinatorium, which have heavy pigment. The larval stage is also known as the picodium fluke. Adult bugs live in the intestines of waterfowl, which are infested by eating fish that harbor larvae.

In the guts of the waterfowl, the membranes that surround each larva spread out, and the worms mature after a few weeks. The eggs laid by the adult worms are excreted in the excrement of the bird, and the eggs that fall into the water develop into free-swimming larvae, which parasitize the snails. After a few weeks, the parasite leaves the snail and begins another cycle of sending a suitable fish host.

When the parasite reaches about 1 mm wide, a black membrane grows on each bug's body, forming unique spots under **. Mild black spot infection is not harmful to fish, because the life cycle and environmental conditions are complex, and black spot disease will not be transmitted from one fish to another.

3.**Method.

In general, drugs have poor penetration of the cyst, and even if drugs are used, they are basically ineffective. At this time, we can use the method of suddenly changing the temperature to make the parasite black spots on the koi fall off by themselves, because the ability of the koi to adapt to the temperature is much stronger than that of the parasite, we can change the temperature suddenly, but this temperature must be within the temperature that the koi is adapted to to operate, so that the parasite does not adapt to the sudden change of temperature, and dies and falls off.

The slow growth of koi is not necessarily the cause of fish food, it may be a problem with the tank and water.

If you want the fish to grow fast, you have to use a big tank, how big a tank to raise a large number of fish! In addition, to ensure water quality, fish farming should first raise water, filtration should be strong, and the temperature should be moderate.

Koi eat without moderation, if purely for the sake of growing fast and feeding more, but half the effort, you can consider taking a small meal method, about 4-5 hours apart, feed once, not too much each time!

Generally, they are fed "germ" feed, which will make the koi grow a little thicker! You can also add some lactic acid bacteria, koi will have a great appetite, and if you eat too much, you will naturally be strong. If you want the koi to grow fast, you can feed a little more in the month, the fastest growth of koi in a year is this period, and it will not grow much if you feed too much in winter, and it may also affect the pattern and white matter.

The situation you mentioned is that the fish has white spot disease, and my koi fish also have white spot disease, and the treatment is as follows:

1. Fish out all the fish and clean all the water in the fish tank;

2. Clean the fish tank and fill it with water, and put in 1-2 catties (city catties) of large grains of salt to dissolve it;

3. Turn on the heating rod and set the temperature to 30 degrees Celsius;

4. Fill half a basin of water in a basin, pour in two caps of Hino brand "Special Effect White Point Net" (white point net bottle caps) and stir well;

5. Put the fish one by one into the medicine basin and soak them for 5-10 seconds, take them out and put them back in the fish tank. Be careful not to soak for too long, otherwise the fish will be poisoned and die.

6. After completion, pour half a bottle cap into the fish tank Hino brand "special effect white spot net" (increase or decrease depending on the size of the fish tank), my fish tank size is 120cm*60cm*35cm. Every 2-3 days, put half a cap of "special effect white spot net" into the fish tank. If you put it 3-4 times, you don't need to put the medicine again, and you can see it again after a week, and the sick fish will be cured early.

Hehe. This treatment has a special effect, and the fish will be seen well on the same day, and there will be significantly fewer white spots. After a week, the heating rod can be removed and not used. This is my personal experience, and this process is also done, I don't know if it will help your fish.

Give it a try. In addition, Hino brand "special effect white point net" can be bought in the flower, bird and fish market, and it is not expensive, a few yuan a bottle.

Change the water frequently, disinfect the fish tank, and go to the market to buy some fish medicine and put it in the fish tank.

The correct way to raise koi:

1. Control density.

To breed koi fish, the first thing to do is to control the density. It is not correct to breed too many koi fish in small tanks, which can cause them to grow poorly. Generally speaking, if the size is 6*3*15 cm fish tank, the number of koi fish that can be raised is about 6, and you can't raise too much.

2. Change the water regularly.

It is also very important to keep the water quality suitable for koi fish farming. Therefore, it is necessary to change the water regularly and clean up the impurities in the fish tank to provide a clean environment for the growth of koi. Specifically, the frequency of water changes can be controlled to 3-7 days, with more frequent water changes in summer and slightly longer intervals in winter.

Each time you change the water, you can change a third. In order to ensure that the water temperature does not change drastically, it is necessary to control the flow rate of the water and slowly inject new water.

3. Reasonable feeding.

Another important issue is feeding, which requires the use of normal feeding methods. First of all, you need to choose a good food, koi fish are omnivorous, so try not to use only one food, so it may be insufficient in nutrients. You can combine plant and animal foods together, such as greens, earthworms, bloodworms, etc.

It can be fed once or twice a day, once in the morning and once in the afternoon.

Fourth, appropriate lighting.

When raising koi fish, you also need to provide a certain amount of light every day. Especially if there are other plants in the tank, light needs to be provided for them to photosynthesize. However, in the summer, considering that the light is stronger, they can be properly shaded.

5. Precautions.

In winter, special treatments can be carried out to allow the koi to survive the winter, placing them in pools with a water temperature of 5-1 degrees. At this time, the number of feedings does not need to be too much, and it is enough to feed once every 3-5 days.

Koi, not afraid of the cold, put a little salt is not easy to get sick... Small fish, feed twice a day, change 1/3 of the water every day, or change every 1 or 2 days... Feeding and changing the water is to make him grow ...

If you don't want to be long, it's enough to feed once a day... Small tank, if the water is deep, the fish will lack oxygen... Carp is very easy to raise...

You might as well find a fish pond, river or park lake to release it! A tank that is too small will kill the fish, so buy a few guppies and raise them!

The bleeding is caused by bleeding on the surface of the body and the fins of the fish, and there are also a small number of bleeding spots on the tail fin in the first picture, which is caused by subcutaneous parasites.

A dark belly should be normal. This fish has a black belly.

The gills look normal, but if you feel abnormal, it should be a parasite problem.

There is also unfortunate news, there are not many people who can survive in this state (the body is bent), but I will tell you how to do it.

The first, the effect is slightly better, with about 3 grams of potassium permanganate, add potassium permanganate once every 2 or 3 days, and you can add it directly to the fish tank. The tank will turn red, but as long as the fish doesn't overreact. Pay attention to fasting during the medication. It will get better in about 10 days.

Second, if potassium permanganate is hard to find, put two to three grams of salt in water and add it every three days or so. This method will get better in about two weeks......

Good luck!

Add a point, you should buy this outside, if so, next time you want to do the same, be sure to choose well, observe whether there is a white film or red and swollen place on the surface of the fish, if there is, it means that the fish is infected by germs. Don't buy it.
