1, the choice of parent fish: pay attention to the age of the luhan fish, at least in the age of more than 8 months to reproduce. In addition, we need to pay attention to the health status and appearance, to choose healthy without disease and obvious characteristics of the breed. The parents of the Luo Han fish will have a great impact on their offspring, so special attention must be paid to the selection of parents.
2. Pairing: In the specific breeding, it is not enough to put the male and the female together. If they are put together, the male may attack the female. Therefore, they need to be separated by a net to see if they can pair up and then put together when they can get along well.
3. Spawning and fertilization: After mating, they need to be kept in a quiet place. Prepare a tray for the female to lay eggs on. The fish is fertilized in vitro. After the female spawns, the male ejaculates to complete the fertilization process. After this process is complete, it is recommended that the females be removed to prevent them from eating the eggs.
4. Hatching: Distinguish whether the fish eggs are fertilized, and then incubate the fertilized eggs under appropriate conditions. Generally speaking, after about a week can be hatched. During this incubation period, the male takes care of the young.
During the reproduction, it is necessary to ensure that the surrounding environment is suitable, and one of the important aspects is the water temperature. In general, after selecting parent fish and placing them in a separate tank, the temperature can be maintained between 28 and 30 degrees. When the small fish are hatched, the temperature can be about 30 degrees, not too low.
