How to put the fish that has just returned from express delivery into the tank and how to raise it after it is put into the tank?

The fish that has just returned by express delivery, it is best to overtemperature it first, so that the water temperature where it is located is gradually consistent with the water temperature in the fish tank. After that, you need to pass the water, that is, exchange the water in the bag with the water in the fish tank once every ten minutes, a total of five times. In addition, the new fish should be disinfected, because it may carry harmful bacteria and pose a threat to other fish in the tank, so it should be soaked in potassium permanganate for a period of time before entering the tank. First, how to make the fish just returned by express delivery into the tank 1, overtemperature: the fish just returned by express delivery must be overtemperature first. Put the fish bag into the fish tank from the top, but to avoid contact with water, just immerse the bottom of the bag in water, so that the temperature of the water in the bag is gradually consistent with that in the tank, and the fish will not feel the temperature difference.

2. Crossing the water: Because the water in the bag is different from that in the fish tank, if the environment changes suddenly, the fish may feel uncomfortable, so it is necessary to cross the water. First scoop out one-tenth of the water from the bag, pour it into the fish tank, then scoop out the same amount of water from the tank and pour it back. Then wait ten minutes to see how the fish behave. If there is no discomfort, you can continue to exchange. Usually after five exchanges, the fish adapt.

3. Disinfection: If the new fish carries germs, it will soon infect healthy fish after entering the fish tank. In order to avoid this situation, it is necessary to pour yellow powder for disinfection and sterilization at the first time.

Second, how to raise the fish safely after entering the tank, it is best to isolate it first. You can put an isolation net in the fish tank to prevent it from contacting the old fish. Generally, you need to rest for a week, during which you should control feeding and change water as little as possible. Once the water quality fluctuates, the fish need to adapt again, which is also very unfavorable to the health.
