The blue man arowana is a relatively popular ornamental fish. Before breeding them, we should first understand their size so as to provide them with sufficient space. When they are raised for 6 to 7 months, they can reach the mature stage. After adulthood, their body length is generally between 10 and 15 centimeters, and their size is not too large. How big they can grow has a lot to do with the way they are raised. If the breeding method is appropriate, the surrounding environment is more suitable for the growth of blue dragon fish, then their size will be relatively large. If the environment is not suitable, it may lead to dysplasia of the blue dragon fish, and then the body size will be relatively small.
The life span of the blue man arowana is generally 5-6 years, which is their average age, and their life span is not too long. Their life span is also affected by the surrounding environment, and some environmental factors have a greater impact on their life span. For example, water quality is a very big factor, if the water is not changed for a long time, resulting in a lot of impurities in the water, then the blue dragon fish is likely to get sick, may lead to their death, life will naturally be short. In addition, there are oxygen, water temperature, feeding and other factors, which will more or less affect their life span, and there are many problems to be paid attention to. Therefore, in the family breeding of blue dragon fish, it is likely that novice breeders will die after two or three years or even one or two years of breeding. If they want to live longer, they need careful maintenance.
