As shown in the picture, the small tropical fish (oviparous) should be the family characidae Neon lipid carp paracheirodon small tropical fish The picture below shows the neon carp paracheirodon innesi, also known as fluorescent lampfish, traffic light fish, neon fish (main feature: red on the back half of the body).

There are two ways of fertilization in fish: the vast majority of oviparous fish undergo in vitro fertilization, and the broodstock discharges the sperm and eggs into the water; A small number of oviparous fish such as some sharks and rays undergo internal fertilization, while all ovoviviparous and viviparous fish undergo internal fertilization. There are three types of reproduction in fish: oviparous, ovoviviparous, and viviparous.

1. Oviparity is the reproductive mode of most fish. Fish lay eggs outside the body, and embryonic development takes place outside the body, relying entirely on nutrients inside the egg.

2. Ovoviviparity The fertilized egg develops in the female reproductive tract, and the development mainly relies on yolk nutrition, and has no nutritional relationship with the mother, or the maternal reproductive tract mainly only provides water and minerals, and finally the mother produces juveniles. Such as guppies.

3. The embryo body of some plate-gill fish is related to the blood circulation of the mother, and the nutrients required for embryonic development not only rely on its own yolk, but also rely on the mother to supply. There are protrusions in the wall of the fallopian tube where the embryo develops that connect with the embryonic body, forming a placenta-like structure through which the mother sends nutrients to the embryonic body. Such as the gray star shark.

Hello: The female fish should be fished out in time after giving birth, so as not to eat her own children. It should be kept alone, because the mother fish that has given birth to the small fish is very weak, so as not to be chased by the male fish.

3.It is recommended to buy a heating rod and adjust the water temperature to between 24 and 26 degrees. 4.

6.If you use tap water when changing the water, expose the water to the sun for three days. 7.

Proper sun exposure, one or two hours a day is enough. 8.The water temperature should be constant, do not always change, the small fish are very weak, and they will not be able to stand the water temperature difference of more than 2 degrees when changing the water.

9.Small fish can be fed chopped earthworms or broken egg yolks, although egg yolks are ideal, but they will pollute the water quality, it is recommended to feed less. Good luck with your fish farming!
