Normally, if the way of feeding is correct or the fish are in good health, they may live for 10 years. If they are raised normally, they can ensure sufficient food and comfortable environment at ordinary times, and their life span can reach 6-7 years. If they are raised improperly or often get sick and have poor physique, their life span will be relatively reduced, and some even die directly.

1. Water temperature: Lanshou goldfish does not require high water temperature, and usually only needs to keep the water temperature between 20-26 ℃.
