What are the precautions for new fairy fish in the tank

What are the precautions for new fairy fish in the tank? Don’t pour the freshly bought fairy fish into the tank directly. First, you need to soak the tank in salt water to disinfect it, and then add the dechlorinated tap water to the tank, and when the water temperature in the tank is the same as that of the bought fairy fish, then pour the fairy fish into the tank slowly. After the fish are in the tank, the owner needs to carefully observe the state of the fish and then fast the fish for a day so that they can fully adapt to the tank environment. If the fish do not have any discomfort after a day, they can be fed in small amounts. Usually, after the fish have adapted to the feed, you can raise the water temperature to 30 degrees and observe if the fish have any other reactions, if not, it is a success.
