Some long-lived tilapia species can live between 30-50 years. Now, according to different varieties, the life span of Luohan fish is also different. Generally speaking, its life span can be between 12-15 years. However, the life span of tilapia cultured at home is generally between 5-7 years. Its life span will also be affected by the surrounding environment. In the case of inappropriate environment, the life span of Luohan fish is short, and Luohan fish is easy to die after getting sick. 1、 How long is the life span of tilapia? Before hybridization, the life span of some old tilapia varieties is very long. When the surrounding environment is suitable, its life span can be between 30-50 years. However, the Luohan fish sold on the market now have been hybridized for many times, and the varieties are more complex and diverse. The life span of these tilapia is also different according to their varieties, but generally it is between 12-15 years. However, this range is appropriate in the surrounding environment. When raising tilapia in the family, it often dies in 5-7 years, because the breeder can't ensure that the surrounding environment is always suitable.
There are many factors that will affect the life of tilapia, such as the size of the fish tank, whether the feeding is appropriate, whether the water quality is good, whether the light is appropriate, and so on. When the environment is not suitable, the growth and development of tilapia is not good, and they are easy to get sick, so their life expectancy will be relatively low. Especially after illness, if it is an infectious disease, it can easily lead to the death of a large number of Luohan fish. 2、 How many years can Luohan fish be raised? Generally speaking, Luohan fish is used for viewing. At the beginning, it was highly ornamental, and people were generally willing to breed it. However, in general, the tilapia cultured for more than 7 years is basically not ornamental. The appearance of the old tilapia doesn't look good. Therefore, after a certain number of years of breeding, farmers will generally automatically abandon it. （LuoHanYuShouMingDuoChang，NengYangDuoShaoNian）
