For example, if the fish tank is equipped with a filter, it can change the water for a long time, or even add water to the fish tank regularly because of the reduction of evaporation.
If there is no filtration system, you can judge the water change interval by observing whether the water quality is turbid and whether the goldfish is anoxic. Generally speaking, the water change interval in summer is short, every 3-4 days need to change water, spring and autumn can be extended to about a week, winter half a month to change water or even longer is no problem.
