Most fish have male and female distinction, but the identification method is often not the same, generally according to the fish's body shape, fetal spots and so on to judge, usually to the breeding period, the abdomen swelling and fetal spots is the female fish. Some fish also have many variations in the process of evolution, such as fins, snouts and so on, which also facilitate us to distinguish their gender.
1. When the time is ripe: Fish are not born to lay eggs and be fertilized. They must go through a period of time until they are sexually mature before they can reproduce. And most fish have a certain breeding season, after entering the breeding season, they will begin to mate and spawn. So if you want to breed, you have to make sure that the fish are mature.
2. Parent fish pairing: The breeding of fish generally requires one male and one female. However, the pairing of parent fish is often not artificially controlled. Therefore, it is best to put the fish into the breeding tank according to a certain ratio of male to female, so that they can complete the pairing by themselves. After pairing, the fish will often swim together and feed together, at this time, isolation can be considered.
3. Wait until spawning: Usually the fish will have certain signs before reproduction. The abdomen will expand, the fetal spot will become particularly obvious, and the appetite will decrease. At this time, it is necessary to pay attention to observation. Generally, the fish will spawn in the evening or at night. It is better to fish out the parent fish after spawning, so as not to eat the eggs by mistake and affect the number of hatching small fish.
