Peacock fish are oviparous fish. They are fertilized and developed in vivo. When they breed, the male fish will chase the female fish first. If the female fish accepts the pursuit of the male fish, then they will chase each other. In the process of chasing, the reproductive foot of the male fish will be inserted into the reproductive hole of the female fish and fertilization will be completed. The guppy mother fish will not give birth immediately after fertilization, and the fish eggs will develop in the fish for about a month, and will not be born until the fish eggs become small fish. First, how does the peacock fish give birth to small fish? The peacock fish belongs to ovoviviparous fish, and their reproduction mode is fertilization and development in vivo. When guppy breeds, the male fish will pursue the female fish first. If the females are interested in mating, they will chase each other with the males. When chasing, the male fish will transform the anal fin into a reproductive foot, and then insert it into the female fish's reproductive hole, and then fertilization is completed. After fertilization, fish eggs need to develop in the mother for about 20-30 days before they can be born.

Second, how to raise guppies and small fish 1, isolation: After guppies breed small guppies, breeders should isolate them to avoid the situation that big fish eat small fish. When separating small fish, don't choose a fish tank that is too big. It's best to equip it with a thermostat, and control it at about 25 degrees to keep the water temperature constant.

2. Keep the environment stable: the breeder needs to control the stability of the water quality in the tank, because the small fish are not adapted to the external environment when they are born, and the big fish will be weak, so it is better for the breeder to use the original water for breeding, so that they can adapt and recover quickly. In addition, the breeder should not worry about changing the water for them, and can wait until they recover before changing the water to avoid accidents.

3. Feeding: Pay attention to the feeding of food. The adaptability of small fish is weak when they are born. The breeder chooses to crush the egg yolk for feeding, and then feed them with live bait after they have adapted for a period of time. In addition, because the big fish is weak, the breeder should choose live bait with high nutrition, such as Daphnia.
