Luhan fish is a relatively common ornamental fish, which is more popular with farmers. There are many varieties of it, and the differences between different varieties are quite large. How long the Luo Han fish can grow has a lot to do with its genes, because it is a hybrid fish. Different varieties can reach different lengths. For example, for the general pearl species, they can reach a length of 23-30 cm, which is relatively small. For varieties of the golden flower line, their length can be between 28 and 42 centimeters, but between 38 and 42 centimeters is relatively rare.
Then there are some red horse, rainbow and other varieties, they are relatively large, the length can be between 35-40 cm, but it grows relatively slowly, about 20 cm a year. For example, the growth rate of Desa is the slowest, it takes 3-4 years to complete growth, and its length is between 25-35 centimeters. In addition, how big the fish can grow is also related to the specific breeding methods, which need to adopt appropriate breeding methods to raise them.
Luhan fish is a hybrid fish. For some of the old version of the Luo Han fish, their life expectancy is relatively long, if properly cultured, they can even live for 30-50 years. However, as the hybridization continues, their genetic variation is very large, and their life span is also decreasing. The life span of today's Luhan fish species is generally between 5 and 10 years. However, for the average novice breeder, their life span will be shorter, maybe in two or three years or so they will die. For some more experienced breeders, the life span of Luo Han fish may reach 8-10 years.
