What is the most susceptible cause of cold water aquarium fish to die?

Generally not, unless the water in which the fish live is completely frozen. The reasons why fish do not freeze to death in winter are as follows:

1. Water has a characteristic, which is thermal expansion and contraction above 4 degrees Celsius.

The following is heat contraction and cold expansion, which means that at the bottom of 4 degrees Celsius its density is the largest, and conversely, under the water, it is also the most dense, and the temperature can be maintained at 4 degrees Celsius.

2. Fish is a cold-blooded animal, the body temperature changes with the change of water, and does not maintain a constant temperature, as long as the water temperature is not low to zero degrees, the water in the body of the fish will not freeze. Because cold-blooded animals don't need to use their own energy to warm or cool down, they also need relatively little food. Because they are more likely to accumulate enough energy, cold-blooded animals also have a shorter reproductive period.

3. There is an antifreeze protein in the fish, and scientists say that ice crystals will form in the body fluid of the fish, making the fragile cell membrane.

However, antifreeze proteins will adhere to the surface of the ice crystals and act as a deterrent to the ice crystals. When proteins attach to ice crystals, the ice is forced to expand in the middle of them. If the expanding ice mass is large enough, the ice will swallow the protein instead of continuing to grow, which slows down the expansion of the ice crystals.

Because fish are creatures in the water, the fish themselves make antifreeze proteins to help. They survive in icy water...So the fish will not be coldly killed...

Fishes are ectothermic aquatic vertebrates that are covered with skeletal scales, breathe in gills, swim through the oscillation of their tails and trunks, and coordinate their fins, and feed on their upper and lower jaws.

In very low temperature weather, after the lake or river water is frozen, the fish will be frozen into the ice, and the probability of such fish coming back to life is relatively small, if the freezing time is relatively short, it will still be alive.

Fish don't freeze to death easily, but they die of lack of oxygen in the water.

Hello, cold-water fish always die and that's because the chlorine in the water is too heavy. The fish does not feel that the full gills will turn white and slowly die.

Hello, the biggest reason why the fish in the fish tank are easy to die in the summer refrigeration,It's a sudden drop in temperatureIf the fish don't adapt right away, there will be a lot of death

Suddenly changing the environment in which the fish live requires a transition period, and if the temperature difference between the water is too large, the fish will become sluggish, stop eating or catch a cold, or even die as a result. Therefore, to keep the water temperature stable, the temperature difference should not exceed 3. The most important thing for fish to change the environment is to maintain the original environmental state, water temperature, pH, is the most influential factor, if you can't be sure, you need to slowly pass the water until the fish adapts, so that the fish can survive.

SolutionWhen the refrigerator is turned on, you can turn on the low power first, and then, only for a few minutes, let the fish get used to it. If the temperature is very high that day, then you can turn on the refrigerator for a while, and after 5-6 consecutive days, let the fish get used to the temperature, and you can continue to turn on the refrigerator to work.

Secondly, pay attention; In summer, fish farming should first pay attention to avoiding light, light has the greatest impact on temperature, and at the same time, oxygen pumps should be used to oxygenate at all times, so as to avoid the death of fish due to lack of oxygen. In addition, daily feeding should not be too much, otherwise it will accelerate the growth and reproduction of bacteria, and the uneaten food should also be cleaned out.

No, under normal circumstances, unless all the water turns to ice, the fish will die if they can't breathe, as long as there is water underneath, there will be no problem.

1. Tropical ornamental fish eggplant has high requirements for water temperature, poor adaptability to water temperature, and is more sensitive to temperature changes, so the drop in water temperature can easily lead to fish death.

2. Usually the fish can only adapt to the water temperature of 18 to 32 degrees, and the temperature difference does not exceed 3 degrees. A sudden drop in water temperature will inevitably lead to the death of the fish. The water temperature drops slowly, which is acceptable for healthy fish, and some fish are prone to death.

When the water temperature is lower than 22 degrees for a long time, the fish will have a slow metabolism, a decrease in the growth rate of raw mandarin oranges, loss of appetite, and white spot disease.

3. When the water temperature drops, the heating rod can be configured to increase the water temperature.
