The newly bought fish needs to be put into the water before it is put into the fish tank. After the water is generally too warm, scoop some water from the tank into the bag, and then scoop some water out of the bag, once every other time, usually repeated five times, you can slowly take out the bag and let the fish swim out of the bag into the fish tank.
1. Disinfection: In order to avoid some harmful bacteria in the newly bought fish, it is necessary to disinfect it. Disinfection generally uses potassium permanganate or chlorine dioxide, after mixing these drugs into solution, soak the fish in it for about ten minutes, it should be noted that the drug concentration should not be too high, otherwise it will produce some adverse reactions.
2. Overtemperature: The adaptability of fish to temperature is limited. Even for eurythermal fish, sudden changes in water temperature can cause some stress reactions. Therefore, before preparing to close the cylinder, it needs to be overheated. Put the bag of fish into the tank, let the temperature of the water in the tank and the temperature of the water in the bag gradually coincide, so that the fish will adapt.
3. Closing the jar: Before closing the jar, what needs to be done is to pass the water. The method has been mentioned above. What needs to be noted is that when passing the water, do not exchange too much water at one time. Changing too much water is also harmful to their health. The first two times can be changed by one fifth, the third time by one third, and then by half. Basically, there is no problem.
