Toward the end of the gestation period, a week before the putative delivery, the female can be transferred to a prepared maternity tank, pouring water from the common aquarium into it. In such an aquarium there is a dividing wall, so the fry will not suffer from a hungry female.
On the day of pregnancy, the female cannot be transferred to such a reservoir, otherwise miscarriage will occur. When the female is ready to give birth, she can swim slowly, or look for a lonely place in the aquarium.
For some genera, she will produce 10-60 fry, although some mature females can give birth to up to 200 babies.
How long is the birth? Usually a few days.
For 1 day, the female can bring all the fry, and it happens that one fry per day. If childbirth occurs in the general aquarium, make sure that there are many bushes of living plants in it, in which kids can save their lives.
Unfortunately, the fry are clearly visible, so they become victims of parents and their neighbors in the aquarium.
How to determine readiness for childbirth? Before this process, the body of the female is trembling, she is immobile, she has no appetite (the food can spit out). If a heater is installed in the tank, then the female may be near him.
Also the listed signs can testify to premature birth. During the birth itself, the tail of the female twitches, she freezes for a few seconds.
Lively and nimble fry emerge from the anus, they immediately swim actively, starting an independent life.
See how the guppy fry are born.
The female guppy may become pregnant again, even a few hours after giving birth. It can store male spermatozoa for one year, and from one fertilization up to 8 pregnancies can occur, in case of favorable conditions in the aquarium. For one life (3-5 years), a female fish can give life to 2,000 young birds and more.
One day before birth, an anus may develop swelling, if there is none, this is a clear pathology.
After 2 weeks the babies will grow up, grow to 1.5-2 cm in length. At this age, you can sort the fish by gender.
Young females of this age can be recognized by the first sign of sexual dimorphism – they have a dark spot at the bottom of the abdomen, at the base of the anal fin. You can transplant males and females in different aquariums, pouring in there the “old” water from the previous aquarium, which is usual for them. In silvery and light breeds of guppies, sex differences are more difficult to determine – the females on the abdomen will have a barely noticeable white spot, not a black one.
It will be easier to find out the sex of the fish at the age of 1.5 months, however late periods of sorting can provoke an early pregnancy.
The danger for pregnant females of guppies is plystophorosis. Fry can become infected from the mother.
The fish looks sluggish and faded, the tail fin descends, the female swims at an angle of 45-60o. Sick fish can bounce, trying to return to the original, the normal position of the body, refuses to eat. Plystophoresis is not treated, so a pregnant fish cannot survive.
It is destroyed, and all the scenery, equipment must be strictly disinfected.
Fry that have not received enough light and protein can suffer from scoliosis. The causes of scoliosis are not well understood, sometimes this disease manifests itself in tuberculosis.
It is believed that the main causes of spinal curvature are stress, injuries, pathology of the development of an egg, improper feeding of a pregnant fish, oxygen starvation.
