If the lack of oxygen in fish transportation, it is possible to slow down, and it needs to be warmed up in time to explode oxygen. Usually, when the weather is hot, try to avoid buying fish, because because of the high temperature, the dissolved oxygen in the water is relatively low, so it is difficult to insist on transportation. If you want to buy it, you'd better ask the merchant to add some ice bags, so that you can cool down properly, and the bags for fish should be bigger and have more water.
1, disinfection: After buying new fish, the first thing to do is to disinfect. Because the fish bought may carry harmful bacteria, once it enters the fish tank, it will cause harm to healthy fish, so it needs to be disinfected. The method of disinfection is very simple, prepare a container, which is filled with trapped water, and then put a proper amount of potassium permanganate or chlorine dioxide, soak for a period of time.
2. Overheating: After disinfection, the fish needs to be overheated. Because the temperature of the water for new fish is different from that of the water in the fish tank, if it is directly put into the tank, the temperature fluctuation will stimulate it and even cause the fish to die. So first put the bag slowly from the top of the fish tank, let the water pass through the bag, so that the temperature will soon be consistent.
3. Pass the water: After it is too warm, it is necessary to pass the water, that is, to exchange the water in the bag and the fish tank. First scoop out one tenth of the water from the bag and pour it into the fish tank, then scoop out the same amount of water from the tank and pour it back, let it stand for ten minutes, and then exchange it for the second time. About five times in total before the bag is slowly removed to allow the fish to enter the tank.
