Ideally, heding red goldfish can grow to about 15 cm. From infancy to adulthood, when properly raised, heding red goldfish can grow to about 15 cm, and some individuals can even grow longer. Its life span is between five and ten years. However, if the water quality, diet and other aspects are appropriate, and the goldfish also has good genes, its life span may exceed ten years. 1、 How big can the heding red goldfish grow? In theory, the general heding red goldfish can grow to about 15 cm. How big it can grow is limited by many factors, such as its own genes and the feeding environment. In the feeding process, it should eat more live bait such as earthworms to increase nutrition. The water in the fish tank should also be changed frequently, about one-third of which can be changed each time. The breeding density should not be too large, otherwise it will lead to insufficient oxygen and fighting. By doing this, they can grow rapidly and grow bigger. 2、 How long is the life span of heding red goldfish? The life span of heding red goldfish is about five to ten years, but there are individuals over the age of ten. Its life is closely related to the internal environment of the fish tank. If the water quality is clean, its life may be prolonged. If the pollution is serious, it may grow poorly due to infection and disease, or even die early. Therefore, if they want to live longer, they should pay attention to maintaining good water quality and feeding clean food.
If the heding red goldfish bought from the fish and bird market does not live to the average age, it may be that the goldfish itself has been years when it was bought or there are problems in the feeding process of the fish owner. （HeDingGongJinYuNengChangDaoDuoDa，ShouMingDuoChang）
