Self raised koi always die, why?

Most of the reactions of these aquarists are: My fish are good when they bought them, and my water quality looks okay, why do they have hypoxia, ulceration or death?

In exchange for some feed fish, because the indoor water temperature is unstable, I can not ensure that they all survive, and the feed fish I bought before have also been wasted a lot, and finally they are fed to the chickens, so this time, I also learned to be obedient, and threw them directly into the yard, the temperature is only a few degrees, and they are alive and well. In other words, cold-water ornamental fish rarely get sick at low temperatures.

However, when I fished some forage fish to feed the water tigers, I still found some problems.

If you don't look closely, take a look, the quality of these grass goldfish is very good, there are probably no body surface problems, the color is also good, and the individual is considered large, and I really can't bear to feed it. However, after my careful observation, many grass goldfish have some mucus shedding on their body surface, and their bodies are pitted.

That is to say, just like a disease that appears in the swallow fish, I once said, it is not the so-called loss of scales, but a parasite, and the loss of scales is the lack of scales, and this phenomenon is that there are some holes in the body, and it cannot be said that the scales are lost.

In addition, there are some grass goldfish with dark spots on their bodies, which is a sign of physical weakness.

These grass goldfish in the low temperature environment before entering the tank, absolutely will not break out of any disease, once the water temperature into the tank is high, whether it is parasites or germs, immediately began to be greatly active, plus our previous water quality is not well raised, then, a few days later, either water mold, white spots or ulcers all around.

If we buy such grass goldfish, it is still recommended to use salt water for a while, even if it is a percent.

Three or five minutes can also be, which achieves the effect of deworming and sterilization, and then whether it is over-temperature or over-water, it must be longer, especially if the indoor water temperature is 25 degrees and above.

This is a grass goldfish, and the last point is to raise large grass gold, not too dense. Most of the koi we buy are earth cannon koi, because it is a cold-water fish, all the problems of the above-mentioned grass goldfish, the koi will not fall all of them, therefore, in the selection of fish, over-temperature water, water raising, or inspection and quarantine, we must be cautious.

Of course, if the breeding environment is very good before purchasing, and there is no mesoscopic problem with the state and body surface of the ornamental fish, you don't have to quarantine, but it is best to be in the same tank and the same batch of fish, and you must not blindly mix and combine the tank, otherwise it will die ugly.

As long as it is a new aquarist who raises koi, most of the fish tanks will not be too small, but some use a one-meter tank or 80 tanks, I still advise you, the kind of koi fish of twenty or thirty centimeters, we still have to look at it, raise koi in this kind of small tank, don't be too delusional.

Because you can't raise it, none of my lives have ever died.

It may be because you feed a lot of fish, or you don't change the water regularly, or you don't filter the water properly, which can lead to the death of the fish.

Because koi fish are social animals. When you raise a koi fish yourself, you can't meet its growing conditions. So koi always die.

Because the technology is not good, you don't know what kind of living environment the koi is suitable for, and you don't feed it according to the time, so it dies.

The high oxygen content in the water will cause the fish to be highly active, resulting in the phenomenon of tank jumping; There is also a situation where the fish will beat violently when fighting, and if the difference between the water surface and the height of the tank is not high, it is unlikely to jump out of the tank accidentally; According to observation, the latter has more tank jumping phenomenon, mainly because of the high water level and small fish tank, not to mention that the carp itself has a diving hobby, or how to say "carp jumping dragon gate". There is also a situation that the fish are usually fed very fixed, forming a fixed diet like, when suddenly one day is not fed at this time, it will be overactive and jump the tank, of course, the best way is to buckle the lid.

1. When breeding koi fish, it often happens that they die in a short period of time. First of all, it may be that the quality of the koi itself is not good, and it is a koi with a relatively weak physique. In addition, the surrounding environmental factors are not well controlled during the breeding process, resulting in their death.

2. Fish selection: If you want to make the farmed koi not easy to die, you must first choose robust fish when you buy fish. It is best to look full, have complete and symmetrical scales, a large, positive tail, and have a more pronounced characteristic of the species.

3. Equipment: After choosing the koi, it is a problem with the equipment. The first one is the fish tank, you should choose the right size fish tank, not too small. Then there are other equipment in the water tank, such as some lighting equipment and aeration pumps, etc., which need to be prepared in advance.

4. Water quality: To breed koi, it is necessary to keep the water quality suitable, so that the koi is not easy to die. Specifically, water temperature, pH value, etc. are all things to pay attention to. In particular, the water temperature should not be lower than 20 degrees Celsius when breeding, as it is easy to cause the death of koi if the water temperature is too low.

5. Water change: In order to keep the water in the fish tank in a clean state, it is necessary to change the water regularly. The water change can be adjusted according to the season, once every 3 days in summer, once a week in spring and autumn, and once a week in winter with two hail leads.

When changing the water, be careful not to allow the water temperature to change drastically.

6. Feeding: Feeding should also be appropriate, so that koi fish are not easy to die. The first is to change the type of food to be fed, and it is necessary to be rich rather than choose a single food. The second is the amount of feeding, too much or too little is not good, and it must be controlled.

7. Timely treatment: If the koi fish are sick and do not get timely treatment, it is easy to die. Therefore, after observing the symptoms of illness, it is important to take measures in time.

1.Oxygen insufficiency: This fish is large and therefore has a high demand for oxygen.

2.If there is not enough oxygen, the fish will float at first and die after a long time.

3.Deterioration of water quality: No matter what kind of fish live in the water, the quality of the water also has a great impact on its health, and the deterioration of water quality can also threaten the survival of koi fish.

4.Unable to move: If the fish tank is relatively small and the koi are not active, they will get sick after a long time, and their resistance will decrease or even die.
