The male rectum is oval and flat, while the female has a round and more visible anus. Furthermore, when you press the male’s belly, you will see white semen coming out from the secretion part. Meanwhile, female Ryukin secretes yellow liquid, showing that they are ready to breed. 

Breeding Fish Broodstock

A male goldfish can fertilize two female at once. The male and female Ryukin will chase after one another, and later on, the male will fertilize the eggs released by the female Ryukin. This is called external fertilization.

Fertilized Fish Eggs

The fertilized eggs will hatch into larvae in two to four days. When eggs fail to hatch, you should take them because the eggs may root and reduce the water quality. After that, you should add an aerator to add the amount of dissolved oxygen because the population is increasing. 

The fish larvae that have hatched have yellow bundles looking like egg yolks around their stomach. The yellow bundles are the food intake that the larvae use for approximately four days. Make sure to feed them with boiled yellow eggs when the food intake runs out. Feed them sufficiently and control the water condition. 

By taking care of them carefully, you will make sure that there are no fish will die. So, that is how to breed Ryukin goldfish. Quite easy, isn’t it?
