Does the weather in Hui Nantian have a big impact on goldfish? I'm afraid they will die

The impact will not be significant. If your fish tank does not have an oxygen rod, just add the same amount of water after returning to Nantian. It is recommended to reduce the amount of water by one-third. The oxygen above the fish tank will be higher than usual. Reduce, if your fish tank has an oxygen rod, I wish you a happy life, and the water should be dried for a day in advance.

Hope this can help you:

The weather in Nantian is very humid
