There are many kinds of fish, and the breeding season is different, but most of them are in spring or autumn. As poikilothermic animals, the activities of fish are often affected by temperature, and some fish can ovulate when the water temperature exceeds 20 degrees Celsius. It should be noted that fish, like people, also need a certain period of time to mature, and before that, they can not reproduce.
1. Parent fish pairing: If ornamental fish want to reproduce, the first thing to do is to pair the parent fish. Usually, as long as the fish are sexually mature, they will automatically pair during the breeding period. It should be noted that during the courtship process, the fish may fight, so it is best to isolate them appropriately. Or put the fish you want to breed into the breeding tank to pair up.
2. Waiting for spawning: After the ornamental fish pair up, they will often swim and feed together. At this time, it is necessary to pay attention to observation to see if the belly of the female fish has become larger, and how the color of the fetal spot is. If the color of the fetal spot is relatively dark, it indicates that it is ready to spawn, and a quiet environment needs to be provided to avoid dystocia.
3. Incubation of fish larvae: Spawning is usually in the evening or late at night. After spawning, the parent fish should be fished out to prevent them from swallowing the fish eggs. In the process of hatching, we must pay attention to the water temperature, after the larvae come out of the membrane, the first day does not need to feed it, the second day can feed a little cooked egg yolk, but finally use a special tank to feed, otherwise it will spoil the water.
