, new fish and old fish should be mixed in tanks, the first thing to do is to disinfect, because they may carry some harmful bacteria, which may infect each other if not handled properly. The method of disinfection is very simple, prepare potassium permanganate solution with low concentration, and soak the fish in it for a period of time, usually about 15-20 minutes.
, because the water temperature of new fish and old fish may be inconsistent, if the tank is directly closed, one side will certainly feel uncomfortable, so it needs to be overheated. If you put the new fish in the old fish tank, put the new fish in the bag first, then dip the bottom into the tank and wait for ten minutes. If the old fish is put into the new fish tank, the old fish is packed in a bag and put into the new tank.
crossing In order to adapt the fish to the new water environment, repeated water crossing is also needed. Scoop out one tenth of the water from the fish bag, pour it into the fish tank, and then scoop out the same amount of water from the fish tank and pour it into the bag. Wait for ten minutes and exchange again, about five times, the fish in the bag can adapt to the water body of the fish tank, and then the bag can be removed.
, in order to prevent conflicts between new fish and old fish, it is better to isolate them for a period of time to prevent them from fighting. You can put an isolation net in the tank so that they can't touch it, and then remove it after a week so that the fish can swim across.
