The precursor of peacock fish giving birth to small fish

The peacock fish is a very beautiful tropical ornamental fish with the title of "millions of fish". That is because the peacock fish has a very strong reproductive ability, but what the peacock fish needs to pay attention to is to separate the big fish from the small fish, otherwise the big fish will eat the small fish. it is very important to know the precursors of peacock fish giving birth to small fish, so let's take a look!

Breeding habits of peacock fish

Peacock fish is an oviparous fish with strong fecundity and early sexual maturation. Young fish can reproduce after 3-4 months of rearing. The late or early sexual maturation is closely related to water temperature and feeding conditions. Peacock fish give birth once a month, depending on the size of the female fish, each time can produce 10-120 larvae, a considerable amount of larvae a year.

The selection method of peacock fish

The suitable water temperature for peacock fish is about 25 degrees. Generally, a female can give birth to 4-7 litters in a lifetime, but the chance of producing high-quality larvae varies with the change of female's physique, age and health status. That is to say, the quality of F _ 1, F _ 2 and F _ 3 produced by females at the age of 3-5 months is higher. Therefore, in the adult stage, it is necessary to select the suitable parent fish.

Although peacock fish can be regarded as fish for 2 or 3 months, it is still too early for females to breed fish. Early mating will affect the individual growth of female fish and the quantity and quality of their offspring will not be ideal. If the male and female fish are raised in separate tanks before mating, it is generally better to choose about two and a half months of males and three and a half months of females. Because at this time, the males are in a period of exuberant energy, and the females are mature, so that the final larvae are of better quality and quantity.

After giving birth, the peacock fish should be resting alone for 3 days, and then put back into the breeding tank to avoid being prematurely pursued by the male and affect the fertility quality.

When breeding peacock fish, we should pay attention to no more than three generations of breeding fish in the same nest, so as to avoid continuous inbreeding leading to species degradation, resulting in smaller and smaller fish bodies and shorter caudal fins. It is best to introduce the same species of fish for purposeful distant hybridization in order to prevent the degradation of the subspecies and achieve the purpose of improving the species.

The precursor of peacock fish giving birth to small fish

1. The fetal class of the female fish becomes large and black, and the female fish itself has fetal plaques, which are very small when conceived, and can not be seen very carefully, but as the birth period of the female fish approaches, the fetal plaques are large and black and look very obvious (the fetal plaques of white children are orange).

2. The female fish swims irregularly in the water, which also occurs when the female fish is about to give birth. The expansion of the volume affects the swimming of the peacock fish.

3. The female fish will find a hidden place to hide, mainly for the sake of safety in production.

4. It is normal for female fish not to eat feed because of loss of appetite during the delivery period.

5. The appearance of the female fish is brighter than usual.

6. The tail of the swimming on the upper line of the fish tank is close to the bottom of the tank. With the growth of a young fish in his belly, the belly of the female fish becomes heavier.

7. the belly of the female fish is close to square, and the larvae are arranged regularly, so they are square.

8. The protruding anus of the female fish is a sign that it has reached the stage of delivery.

9. The peacock fish likes to be alone two days before giving birth, and the fish close to it will chase and bite, in order to protect the young.
