How do guppies give birth to small fish and how do they raise them

Guppies are oviparous fish, which 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, they will chase each other. In the process of chasing, the reproductive foot of the male fish will be inserted into the drain hole of the female fish and fertilization will be completed. Female guppy fish will not produce immediately after fertilization, and its eggs will develop in the fish body for about one month, and will not be born until the eggs become small fish.

1. How do guppies give birth to small fish

guppies belong to oviparous fish, and their reproduction mode is in vivo fertilization and development. When guppies breed, males will pursue females first. If females have the intention to mate, they will chase each other with males. During the chase, the male will convert the anal fin into a reproductive foot, which will be inserted into the female's drainage hole, and fertilization will be completed at this time. After fertilization, fish eggs need to develop in the mother for about 20-30 days before being born.

2. How to raise small guppies

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 too large a fish tank. It is best to equip it with a constant temperature stick, which is controlled 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 suitable for the external environment when they are born, and the body of the big fish will be weak, so the breeder had better use the original water for breeding, so that they can adapt and recover quickly. In addition, breeders should not change water for them in a hurry, but wait for them to recover before changing water, so as to avoid accidents.

3. Feeding: Pay attention to the feeding of food. Small fish have weak adaptability at birth. Breeders choose to crush egg yolk for feeding, and then feed them with live bait after they adapt for a period of time. In addition, because big fish are weak, breeders should choose live bait with high nutrition for feeding, such as water fleas.
