Why do tropical fish die suddenly when there is warm oxygen

There's a lot of stuff in the water!! If you want to be in good health, it all depends on medicine! This is not going to work in the long run!! Let's read more information about fish and open tank water before raising it!

I can be sure that the cause of death is sea salt You must be a novice Obviously, they are all freshwater fish and tropical fish!! What sea salt do you add? They were all "salted to death" by you with sea salt. Even if you are sick, you should isolate and use salt (you can't use sea salt), and you should be cautious about using the whole tank!

Arowana is a large freshwater fish.

Saury Origin: Mekong, Chao Phraya and other river basins, as well as the waters of parts of Africa Amazon River basin in South America. It is also a freshwater fish.

Map Origin: Guyana in South America, Venezuela, Amazon River Basin in Brazil. The same is a freshwater fish.

Parrot Yours must not be a parrot fish in the sea, it must be a blood parrot fish, it is a hybrid of two species of cichlid fish, and it is also a freshwater fish.

Here's a quick look at some of the tropical fish.

1. Do not add those chlorination solutions, nitrifying bacteria, water purification agents and sea salt.

2. According to what you said, the oxygen temperature is normal, and there is a habit of changing the water regularly, so it can only be the problem of this water change.

3. The water that is replaced should be trapped water, that is, water that has been left for three or four days (natural dechlorination). The amount of water change, generally once a week, each time 1 5-1 4, the water temperature can be 1 degree higher than the water temperature in the tank, and should not be lower than the water temperature in the tank.

4. After writing the above words, I saw that he died 6 days after changing the water.

Dead fish, if it is not a fish injury or fish disease, it can only be due to water quality. When people are not at home, or when they fall asleep at night, there is a power outage for a long time? Causing a lack of oxygen or a deterioration in water quality due to pump stoppage?

There are too many things added, and good water is produced by raising, not by matching. But I don't agree with the previous classmates about the problem of sea salt. In fact, freshwater fish are also added with sea salt, some are called sea crystals. But in moderation.

This truth is like people's health is made by conditioning, not by eating brain platinum!

In addition, the temperature is on the low side.

I've been in your situation, but mine is only half dead. It's not a problem with sea salt, which is refined in seawater. It's all sea salt.

The main culprit is water purifiers. There's flocculent stuff that settles and gets filtered out very quickly, but a lot of it sticks to the gills, and the fish don't die at that time, but most of them don't survive for a week.

Sudden death is usually a gastrointestinal problem, and I think it should be a problem with the food you fed the day before.

There are too many fake things or the proportion is not good, the fish are viable, not maintained by drugs, it may be that the water is polluted.

You've tortured all your fish to death.

Within a day, the growth environment of the fish suddenly changed, or the resistance of the fish reached the limit.

Dechlorination solution and water purifier are natural enemies of nitrifying bacteria! ~

The situation of coincidentally dying completely will not be a disease, except for the stuffy tank, see if the fish tank is leaking? And I think you must be good at cooking or chemistry, adding so many "spices" at once, or using the fish tank as a test tube, right?

You raise freshwater tropical fish, don't you return the water!! It's no wonder if you put a lot of salt and water purifier and don't die!!

It is recommended not to use water purification agents, and it is better to raise nitrifying bacteria than anything else!

If you are well drowsy in water, there is no need to add chlorine remover, nitrifying bacteria, water purifiers, sea salt, Arowana, saury, and maps. The parrots were all poisoned.

There are many possibilities for aquarium fish to die violently. I don't know how much LZ's water has changed. Whether there is an outbreak of illness within 6 days. If everything is normal. The likelihood of onset is the greatest.

The water change is generally 1 5 1 3 water at a time. Use tap water that has been trapped for 1 or 2 days.

Your fish is also not a very special fish. When changing the water, do not add any medication.

If there is no warning, ask your family what they put in the tank without your knowledge.

What kind of filtration do you use in your tank? That's the key!

The symptoms of hypoxic death in fish are:

1.The water has low transparency, serious water pollution, and low dissolved oxygen, which may lead to the death of fish due to lack of oxygen.

2.Fish have a floating head before they die, i.e., they swallow air on the surface of the water.

3.After the fish dies, the pectoral fin bar is generally stretched to the front position, and the fin bar is whitish.

4.The color of the gills may change, such as bright red or purple, and there is a contaminating buildup in the gills.

5.If you die due to lack of oxygen, the water body may emit a sour cabbage smell, a foul smell, and the water color may turn black or off-white, and there will be a drastic change in water color compared to the previous day.

6.When a fish dies of hypoxia, it may collide, jump, or float below the surface.

The above are the symptoms of fish dying from lack of oxygen, if you notice these symptoms in the fish tank where you keep fish, take steps to oxygenate the fish tank as soon as possible.

The fish can be relieved after hypoxia, but it is necessary to take timely measures to treat it. You can use a tank to hold some water from the fish tank, and then lift it up and pour it into the tank, which can accelerate the flow of water and increase oxygen, which is beneficial to recovery.

If the fish is hypoxic, we need to replenish the pond with oxygen in time so that the fish can breathe normally. When we raise fish, we must pay more attention to his survival conditions.

The time it takes for a fish to float up after dying of hypoxia varies depending on a variety of factors such as water temperature, water depth, fish size, cause of death, etc. In some cases, the fish can float immediately after death, while in other cases, the fish may not float until hours or days later.

When the fish dies of hypoxia, the oxygen content in the body drops sharply, and the bacteria in the fish body begin to decompose the fish body, producing gas, which makes the fish body float. Therefore, the time it takes for the fish to float depends on the rate at which the gas is produced and accumulated. The timing of this process can be affected by many factors such as water temperature, water depth, fish size, current, fish density, etc.

Generally speaking, when the water temperature is higher and the current is stronger, the fish will float faster.

In general, the time it takes for fish to float after death from hypoxia is uncertain and cannot be accurately **. If you find that the fish is dying of hypoxia, it is recommended to clean the fish as soon as possible to avoid the impact on water quality and other fish.

Fish will die of hypoxia for 2 3 hours, after the fish tank is hypoxic, you can use an oxygen pump to oxygenate the tank, generally need to be oxygenated for 2 4 hours a day. In summer and rainy weather, the temperature is low and the air pressure is high, and the oxygen capacity in the water will decrease, so it is necessary to prolong the time of oxygen infusion. Oxygen can also be supplemented by changing the water, generally every 2 to 3 days, and strengthening the filtration system in the tank.

Fish will die of hypoxia for 2 3 hours, after the fish tank appears hypoxic, you can directly use the oxygen pump to supplement oxygen, generally need to flush 2 4 hours of oxygen every day, if it is a medium and large fish, or the feeding density is larger, you also need to keep oxygen.

In addition, in summer and rainy weather, due to the low temperature and high air pressure, the amount of dissolved oxygen in the water will decrease, during which the time of oxygen needs to be appropriately prolonged, so that the fish can grow healthily and will not die due to lack of oxygen.

In addition, the oxygen content in the tank can also be increased by changing the water, and the water can generally be changed every 2 3 days, and the water quality changes quickly in summer, and the water needs to be changed every 1 2 days. The filtration system of the fish tank needs to be strengthened to reduce impurities and bacteria in the tank, and to increase the oxygen content in the tank.
