The reproduction of Ranchu goldfish is a relatively important step in the process of breeding. Generally speaking, the Ranchu goldfish, which has been cultured for about one year, will have the ability to reproduce. Even some of the more precocious Ranchu goldfish, their sexual maturity will be earlier. However, the age of the younger Ranchu goldfish for breeding, laid eggs are prone to defective, that is, the quality of reproduction is not high.
Under normal circumstances, the age of more than two years of Ranchu goldfish breeding, the effect will be better. In addition, we can see from their length whether they can reproduce. Specifically, when their body length grows to about 8 centimeters, they can reproduce, but the effect of reproduction is better when the length is more than 10 centimeters.
May and June of each year is the Ranchu goldfish breeding season. At this stage, first of all, you can choose the parent Lanshou goldfish. It is better to choose Ranchu goldfish with healthy constitution, body size above 10 centimeters and age above 2 years. In order to improve the success of fertilization, the number of male fish is more than that of female fish. Then, place them separately in a fish tank and let them pair naturally. In the process of their reproduction, they need to keep the water temperature suitable all the time, and sunshine is also an important aspect. After goldfish spawn, they need to be hatched artificially. After about 4-7 days, they can hatch out. The newly hatched small fish are not active and do not like to swim, so they can be fed after about 2 days, and they can be fed egg yolk at first.
