Theoretically speaking, the general crane top red goldfish can grow to about 15 centimeters. How big it can grow is limited by many factors, such as its own genes, and the environment in which it is raised. In the process of feeding, we should give it more live bait such as earthworms to increase nutrition, and the water in the fish tank should be replaced frequently, about one third of each time. The breeding density should not be too large, otherwise it will lead to insufficient oxygen and fighting phenomenon. By doing all this, they can grow quickly and grow bigger.
The life span of the crane top red goldfish is probably between five and ten years, but there are also individuals over ten years old. Its life span is closely related to the internal environment of the fish tank, if the water quality is clean, its life span may be prolonged, if the pollution is serious, it may grow poorly because of infection, or even die early. Therefore, in order to live longer, they should pay attention to maintaining good water quality and feeding clean food.
If the crane 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 bought for a long time or there is a problem in the process of raising the fish owner.
