A goldfish typically has a lifespan of 7 to 8 years. Goldfish have been observed to live for more than 10 years or more under good feeding conditions. Since the lifespan of goldfish is related to feeding conditions and feeding methods, the lifespan can be long or short. Usually, in order to make goldfish live longer, we have to do the following three things.

 1. Space is very important. If the space is relatively small and the number of goldfish is very large, then Goldfish are likely to have a short lifespan, and they also tend to age and develop poorly.

2. It is very necessary to change the water regularly. If the water temperature changes drastically in a short period of time, it may affect the life of the goldfish. Therefore, when changing the water regularly, the water temperature should not be too low or too high.

3. Feeding is also a key factor affecting the lifespan of goldfish. Feeding too much or too little, causing the goldfish to be too full or too hungry, will shorten the lifespan of the goldfish and require special attention.
