Guppy fry stage of calf pass in the female’s abdomen. Guppies (Poecilia reticulata) are viviparous fishes.
Because of their size of 2–4 mm, newborn fry are at risk of eating by adults. Therefore, it is recommended to transfer to the jigger or a separate container.
Guppies, like all fish of the order are karbozuboobraznyh, do not possess maternal instinct. The mother gave birth to a female in a common aquarium.
A 3–5 liter pot is suitable as an age tank if 15–20 fry are born. If more – the capacity of 10 liters.
Pregnancy lasts 25–35 days.
Manifested in increasing the size of the abdomen. 2-3 days before the birth, the abdomen is “squared” and a dark spot appears behind.
At the final stage of pregnancy water is not replaced. The temperature is kept constant.
The optimum water temperature in the aquarium is 24–26 ° C.
24-30 hours before giving birth, the female becomes little active, does not eat, keeps near the devices heating the water.
If a separate content of juveniles is planned, then the fertilized female is placed in a prepared container with clean, transparent water and plants.
Plants are recommended for fry.
Floating on the surface:
- riccia floating;
- floating salvinia;
Floating in the water column:
- Elodieus is leafy;
- peristoleum povynichkovy.
Guppy’s skin is tender, easily injured. Therefore, plants with hard scratching leaves, snags, sharp shells are unacceptable.
After one fertilization, the female is able to give birth during the year in the absence of the male.
Childbirth lasts 1–24 hours. Completion is difficult to determine. Leave the female with the fry for 24 hours.
If there are plants, the loss of fry is minimal.
How many fry give birth to guppies depends on the age and size of the female, on the number of genera and species.
In the general aquarium count difficult. Usually 15–60 individuals.
A certain amount of female can eat during childbirth.
Guppy fry are born fully formed. Capable to eat themselves.
Hiding from adult fish.
2–4 mm in length. Colorless to transparency.
With big black eyes.
The growth rate is influenced by the volume of the aquarium and the quality of the water.
During the first week of life, the fry gains 5–7 mm in length. By the end of the second – up to 20 mm.
Full size (40–60 mm females, 20–40 mm males) and sexual maturity reach 4–5 months.
Sex differences occur 14 days after birth.
Males are slimmer. Manifested color.
In females, there is a smoothly contoured, prominent abdomen and dark speck near the anal fin.
Guppy fry need live and vegetable food. Purchased dry contain essential, including vitamins.
Ichthyologists and ichthyopathologists recommend powders Tetra, Sera, JBL.
For fry up to 1 cm long:
- Tetra MicroMin.
- Sera micropan.
- Sera micron.
- JBL NovoTom.
Guppies are omnivorous, but fry need protein for active growth. Protein is abundant in live food.
The food is mobile, which awakens the hunting instinct in fish. Does not spoil the water.
In the early days, use food grown at home.
- “Living dust” – ciliate shoe. The size is 0.15–0.25 mm.
- Naupliya is the larva of Artemia. 0.4–0.6 mm in length. For continuous feeding is not used because of the risk of obesity in fry.
- Microworm – roundworm, nematode. Dimensions: 0.05–1.5 x 0.05 mm. High-calorie substitution naupliyam.
- Phytoplankton – microscopic algae, harmful to an aquarium by water blooms, are important for the diet of fry. Expose a jar of aquarium water to sunlight. After a couple of days, algae will appear. Use a medical syringe to place in the aquarium.
Live food from natural reservoirs are dangerous. There is a possibility of poisoning fish, the introduction of parasites and infection.
Ozone disinfection will help, but it will not get rid of toxins.
Daphnia, also known as the water flea. Size from 0.15 mm depending on age and type. High protein content.
Present vitamins, trace elements. It lives in natural waters.
Mosquito larvae and worms are fed to ground fry.
Bloodworm, he is “Malinka” because of the thick red color. The size is 5–20 mm. Nutritious, but chopped spoils the water.
When buying, pay attention to color. Pale – young, at least useful substances. With a brown tint – old, hard, not stored for a long time.
Do not let the dead moth fish get intoxicated.
Coretra – transparent mosquito larva. 6–10 mm in length.
Predator, food does not produce at the bottom. Therefore, in terms of infection and poisoning is not as dangerous as bloodworms.
It is not enough protein, it is unsuitable for constant feeding.
The straw pipeworm is a pink thread worm with a brown tint. Length – up to 40 mm.
In nature, lives at the bottom of muddy muddy reservoirs. High calories are not recommended for long-term feeding due to fish obesity.
- Useful for the growth of fry and weakened adults.
- Enriched with vitamins, if placed in a prepared solution: 250 mg of multivitamins per 100 g of tubule.
- The most dangerous infections are infections and parasites, intoxication. Before feeding, an extract of 5 days is required to remove food residues.
For fry as a whole, specimens of 1–1.5 mm are suitable. Separate a strong stream of water.
The clump of the shredder is falling apart. Large worms are immersed, feed for fry swims.
Frozen food is not so dangerous. But not all harmful contents are frozen, the chemical composition does not change. The quality of raw materials is unknown.
A bona fide manufacturer cannot guarantee proper handling during transport and storage.
Fully replace live food is impossible. Not processed, nutritious, mobile.
Partly – purchased dry feed, dry daphnia.
- Chopped hard boiled yolk of chicken egg. Before feeding pound, add aquarium water. Squeeze through the gauze into the container.
- Milk powder. For self-cooking, evaporate the milk in a water bath.
- Cottage cheese. Heat sour milk to form a lump – cottage cheese. Wash the cottage cheese and squeeze it into the aquarium through cheesecloth.
- Cereals. Pounded oats (flakes), corn, semolina.
- Chopped vegetables, greens.
Only substitutes feed fry impossible. Use as a dietary supplement.
Eaten remnants spoil the water, which is fraught with fish poisoning. Remove the siphon.
Adult fish hunt and eat fry. Probable loss of 2/3 of the litter.
If the label is supposed to be in a common container, prepare the plants floating on the surface and floating in the water column. Thickets will serve the fry asylum.
Raise the temperature of the water to 26 ° C (gradually increasing over a couple of months).
Feed finely ground “adult” feed. Top dressing: yogurt, dried milk, vegetable food.
For the first couple of months, substitute 1 / 3–1 / 4 of water 2–3 times a week.
Aeration and filtration of water are required.
- Advantages: grow quickly, do not get sick, survive strong individuals.
- Disadvantages: high mortality, the breed will not survive.
The bailout (nursery, spawning) of 2–5 liters for a common aquarium is purchased or made independently from a plastic bottle. With fabric walls (“net”) is not recommended: adult fish bite fry through the fabric.
Spawning place next to the heater and spray. Place the plants.
2-3 days before giving birth, place the female in a nursery. Since the change of conditions is minimal, the transplant will not cause stress to the female, and the offspring will not suffer.
After completing the label, transfer the female to the aquarium.
And also raise the water temperature gradually to 26 ° C.
In the first days (3–6) feed with “live dust”, pounded and dry fry. Add milk and vegetable dressings, egg yolk.
In the first week, set the feed around the clock at intervals of 4-6 hours in metered portions. Remove feces and food residues.
After a couple of weeks, primary sexual signs will appear. Separate the males.
Early pregnancy is dangerous for the female.
Females translate into a common aquarium to reach puberty. At the age of 4–5 months.
Males – in a month.
Advantages: save litter.
Disadvantages: no separate conditions, additional capacity in the aquarium.
The optimum water temperature in the aquarium is 28 ° C. With a gradual decrease of 1 ° C per month for 4 months. An increase in temperature of 2 ° C will cause early (after 2.5–3 months) puberty and a decrease in the size of males.
Choose a heater with a thermostat.
Stiffness up to 10 ° W, pH up to 8.
Provide a compressor and sprayer to ventilate the water. To maintain cleanliness – filter and siphon.
Aquarium capacity – 20–60 liters.
The lighting is intense. Calculate the parameters of the equipment on a special calculator (available on the Internet) and multiply by 1.5. Focus on fluorescent and LED lamps.
Not heated and economical.
If you plan on feeding dry food, an automatic feeder with a timer is useful.
Floating on the surface and in the water column of plants are required. The soil is not needed: make it difficult to clean up feces and food debris.
For the first 5 days, feed with “live dust”, microworms, phytoplankton, and dry food for fry 4–6 times a day. Lighting do not turn off.
On day 6, add to the diet naupliyu. Backlight – 12 hours a day.
Replace 1/4–1/3 of the volume of water daily and siphon.
Drop males into a common aquarium: fish are capable of reproduction.
Add in the diet of daphnia and feeding (yolk, cottage cheese, milk, vegetables, greens), mashed dry food. Feed 3-4 times a day.

For more than a month, add chopped bloodworm, cortex, tubule to the diet. Lighting 8–10 hours.
Water temperature – 27 ° C. Water change and bottom cleaning – 2-3 times a week.
Guppies are unpretentious, but not fry. It is important proper nutrition of fry in the first days after birth. Diverse, frequent, dosed.
Clean, fresh water. Temperature mode.
Without proper keeping, the fry will not reach normal size. The color of the body and fins – spoiled.
