The lifespan of a goldfish is about 7 years. How long a goldfish can live depends on how the owner raises it. If it is raised well, it can even live 8-10 years. Goldfish have very high requirements for water quality. The water source, water temperature, and whether the water is clean will all have an impact on the lifespan of the goldfish. At the same time, the food and feeding habits of the goldfish will also have a great relationship.

Notes on raising goldfish:

1. Many artificially bred goldfish die due to lack of oxygen. In order to avoid hypoxia problems, you can put a Oxygen pump for oxygen.

2. Pay attention to the breeding density. If too many goldfish are raised in a fish tank, it will have an unreasonable impact on the health of the goldfish and seriously reduce the life span of the goldfish.

3. When feeding goldfish, pay attention to the amount of food. Just make it 80% full. Goldfish eats uncontrollably and will continue to eat even if it is full. Avoid eating too much. Too much to overwhelm.
