Do fish die in five days in a courier shop, and why don t fish that come by courier die

Fish can die in five days in the courier shop. If the fish is placed in an oxygen bag, the survival time is generally about three to four days. However, if there are too many fish, they may die in a short period of time. Therefore, it is best to send the fish to a new tank as soon as possible.

The oxygen quality is good enough, and it will not.

Why don't the fish that come by courier die?

Answers. 1.The fish that comes by express is generally placed in a bag, which has a certain amount of air inside, and there is a thermal insulation layer on the outside to avoid the temperature dropping, so it can live for a few days.

2.There is a certain risk in buying fish online, so be sure to choose a reputable merchant, and it is best to ensure that the fish can be returned after death.

3.In addition, if you are still not at ease, you can buy it in a physical store, and there will not be much difference.

There are several reasons why the fish that come by courier will not die:

1.The merchant has fasted the fish before shipping the key, so that the fish empties the stomach and intestines to reduce the energy required for metabolism and reduce the need for oxygen.

2.The fish are packed in sealed bags filled with oxygen, which guarantees sufficient oxygen during transport**.

3.The styrofoam box in the box not only provides protection, but also contains a simple mass for regulating the gas and water quality to ensure a stable environment for the fish to live during transportation.

4.Changes in temperature and air pressure may occur while the fish are being transported by courier, but as long as these changes are not drastic, they will not have an impact on the survival of the fish.

5.For different sizes of fish, merchants may adopt different packing methods, such as small tropical fish with lower oxygen consumption, while large koi fish and arowana require more packing skills and equipment.

Overall, a series of measures to ensure that the fish have enough oxygen**, a stable environment, and a living clump or clump of life during the delivery process are important reasons why the fish do not die during the delivery process.

Under normal circumstances, the noodles in the packaging bag are filled with enough oxygen to dissolve in the sail balance.

Fish is very easy to die of lack of oxygen, in the process of express transportation, in order to prevent water leakage, fish falls, generally seal the fish in the water storage bag, but the oxygen in the bag is limited, a few days of transportation, the fish may turn over due to insufficient oxygen supply. Fish that barely hold on to their destination are also half-dead, and such fish are prone to death.
