First, read the English article below.

Breeding fish is a project that should be taken on by people who are experienced with saltwater aquarium set up and maintenance. While breeding these fish is not difficult, it does require a bit of knowledge about fish feeding and life cycles, not to mention having the right supplies to assure proper tank filtration and ecosystem development. If you want to begin setting up your own aquarium, you may want to consult How to Start a Saltwater Aquarium or How to Set up a Marine Reef Aquarium before diving into breeding fish. Clownfish are external breeders, meaning that the female fish lays eggs and then the male fish fertilizes them after they have been laid. To make this happen you will need to get a pair of clownfish that are already bonded, in other words mated to each other. Many aquarium stores will sell mated pairs specifically for clownfish breeding. If your  store does not have any in stock, they can probably special order a pair just for you. Don't be afraid to ask! The other way you can get a mated pair is to develop two young clownfish into a bonded pair yourself. Begin by buying two clownfish when they are still young. One of the amazing things about clownfish is that they are all born neither male or female, so you don't have to worry about getting one male and one female.  Any pair will do.  Developing into a male or female fish only occurs as the fish get older. The sex of your fish will actually be determined by the dominance of the fish when fighting each other. The dominant fish will change sex into a female and the less dominant will become male. If you are keeping a lot of clownfish in the same tank, only one bonded pair will develop. The most dominant of all will become female and the second most dominant will become male. The rest will remain sexless.  If you want to keep the fighting to a minimum and make the fish change sex as quickly as possible, it is a good idea to get one clownfish that is larger than the other, that way it is clear from the get go which one is dominant.
