Before hybridization, the life span of some old varieties of luhan fish was very long. Under the condition that the surrounding environment was suitable, its life span could be between 30 and 50 years. However, the Arhat fish sold in the market now have been hybridized many times, and the varieties are more complex and diverse. The life span of these fish varies according to their species, but generally between 12 and 15 years. However, this range is suitable for the surrounding environment. When the fish is raised in a household, it often dies between 5 and 7 years, because the breeder cannot ensure that the surrounding environment is always suitable.
There are many factors that affect the longevity of the fish, such as the size of the tank, whether the feeding is appropriate, whether the water quality is good, whether the light is appropriate, and so on. In the case of unsuitable environment, the growth and development of Luohanyu is not good, but also easy to get sick, so their life span will be relatively low. Especially after illness, if infectious diseases, it is easy to cause a large number of deaths of Luhan fish.
Generally speaking, the cultivation of the Luo Han fish is for viewing. At the beginning, its ornamental value was relatively strong, and people were generally willing to breed it. However, in general, the cultivation of more than 7 years of Luohanyu is basically not ornamental, the appearance of the old Luohanyu looks not good-looking. Therefore, after a certain number of years of farming, farmers will generally automatically abandon it.
