How to give birth to fish


How to reproduce mollies at home

Mollies - viviparous fish, a representative of the family Pecilia. Homeland of mollies - fresh and brackish ponds of Latin America. In the home aquarium, you can find different types of mollies, which were cultivated or bred by humans as hybrid breeds.

Despite the many species that differ morphologically, all share one trait - females independently give birth to fry, and do not lay eggs. Molliesia, reproduction and breeding of which is possible at home, can bring offspring both in the general aquarium and in the prepared reservoir. Spawning mollies is possible one month after settling in the nursery of adult fish.

Conditions of keeping and breeding fry

Males and females of different types of mollies may be neighbors and not in conflict, therefore, living in an aquarium with a company of other fish is only a joy for them. They prefer to swim in the upper middle layer of the tank. During the day, they move alone or in small schools (flocks), and at night they form one joint, swimming in the upper ball of the reservoir.

In order for different types of mollies to live comfortably in an aquarium, 10-20 liters of water are required for 1 individual. For fish of one species, an aquarium of 80 liters, for different species - 110-120 liters. At least 3 females should be settled on one male. Fish can breed in the general aquarium (on the condition of a small population) or in a prepared breeding ground. To breed the fry, producers need to be fed for 2 weeks with vegetable food.

Look at the spawning of mollies.

Comfortable conditions of maintenance guarantee spawning in a month or two after settling in a new "house". The cone-shaped organ of the male genopodia is used for fertilization of the female: seminal fluid is transmitted through it, it also allows you to hold onto the female during breeding, and the ability to become pregnant increases. In fact, pregnancy does not come so easily. Only 1 in 10 copulations ends successfully. Males become sexually mature at 8-12 months, females at 5-6 months.

Breeding of all types of mollies is not difficult for the responsible aquarist. However, the fry of this fish are sensitive to water parameters, in particular, to its pollution, so you will have to change the water frequently.

With successful copulation, the male fertilizes at once many eggs, in which the fry begin to develop. Some mature and are born, others remain inside the female until the next generation. In the absence of a male in the aquarium, the female can give birth to another 35-50 days at intervals.

How to care for fry

A pregnant female has a square belly, from the side it may seem that it reaches the head. On the abdomen, from the anal fin, you can see a spot. Pregnancy lasts one month, after which the female gives birth from 50 to 100 fry. Before giving birth, the female tries to find a secluded place - if in the general aquarium, then in the shade and thickets. It is necessary to replant it in a separate spawning 2-3 days before the birth, but not on the day of birth! Otherwise, she will get a lot of stress. Mature mollies give birth more, for the second birth the female brings more than 200 fry.

Molly is not aggressive to his offspring, although there have been cases of eating fry, sometimes random. Often the female is transferred to a separate container with water, where she produces fry. After birth, it is deposited, and the fry continue to grow and develop. After childbearing, the mollies female still has a large abdomen, which means that she did not give birth to all - some already swim, and others mature and appear later. Newborn fry rather large.

Starter feed for calves - vegetable, liquid and live feed for fry, sometimes they are given pounded to dust feed for adult fish. Feeding in small portions, but frequent (2-3 times a day).

See how the fry of mollies appear.

It is important to know

Molly breeding in general or in a separate aquarium is at least not difficult, but you should know some features of the behavior and content of both producers and fry.

  1. Females larger and more mature give birth to more fry than young ones.
  2. Fry mollies are large, but with a weak body, unlike fry guppies and swordsmen. They swim to the surface of the water in a few days, and in the first days of life they lie in the aquarium at the very bottom, sometimes on the leaves of the plants.
  3. Molly fry require frequent replacement of aquarium water, so as not to die.

  4. Salted water (1 tsp per 20 liters) increases their immunity.
  5. If the conditions of the aquarium do not meet the norm, the producers do not give birth to healthy offspring, or do not breed at all. In the worst case, the female gives birth to dead fish or premature eggs.
  6. The reason for the unsuccessful spawning may be a tight reservoir, a very high water temperature (over 28 degrees Celsius).
  7. The main fry feed is ground vegetable food, Artemia naupilii, Cyclops, live dust (ground).
  8. After maturing the fry, they are seated in "opposite-sex" aquariums. Molly females are larger than males; males have a con fin-shaped anal fin - genopodia. In females, anal fin is rounded.
  9. Black mollies sometimes give birth to fry with spots on the body of green, blue. There is nothing terrible in this: mollies from wild nature have a solid and brighter body color, therefore such “tags” are a sign that all hybrid molly are descendants of Latin American natural species.

Guppy aquarium fish - easy and detailed about them

Guppi (lat. Poecilia reticulata) is an aquarium fish that is known even to people who are very far from aquaria, to say nothing of amateurs. Perhaps, every aquarist at least once in his life contained a couple of gupas, and many started their journey with them, and even now they contain luxurious, selective guppy species. To answer all the questions about them, you probably need to write a book, but we will try to consider especially popular ones.

Males of guppies of different breeds

Habitat in nature

The homeland of the guppy fish is Trinidad and Tobago, and in South America, in Venezuela, Guyana and Brazil. As a rule, they live in clean, running water, but also like brackish coastal waters, but not saline sea water. They feed on worms, larvae, bloodworms and various small insects. Because of this peculiarity, they even began to be massively colonized in areas where there is a lot of anopic mosquito, as guppies eat its larvae. The males of guppies in nature are much brighter than the females, but still their coloring is far from aquarium breeding forms. She must protect them from predators, as the fish is small and defenseless.
Wild guppies in nature:

Guppy fish are named after their discoverer (Robert John Lechmere Guppy). Robert Guppy was the first to find and describe this fish on Trinidad Island in 1866.


A small fish, and the males are smaller than females, and usually reach a length of about 5 cm. The guppy lives for 2-3 years, since its small size and warm water speeds up the metabolism and shortens the lifespan.
As for the appearance, it is almost impossible to describe. Guppies are so often and often crossed that even selection forms can be counted in dozens, and already ordinary and even more. Male and female differ strikingly between themselves, but we will tell you about this difference.

Content difficulty

Gorgeous fish for beginners and pros. Small, active, beautiful, very easy to reproduce, undemanding to the content and feeding, it seems that the list can go on forever. However, caution beginners aquarists from buying bright, selective forms of guppies. How to understand that the form of breeding? If all the fish in the aquarium are strictly the same color, the males have long and uniform fins, then these are demanding guppies.

If the males are all different, like the females, there are a riot of colors and colors in the coloring, then these are the guppies that an ordinary aquarist needs. The fact is that as a result of crossing they become very beautiful, but also very capricious, losing their advantages. Hybrid forms of guppies already have weak immunity and are very demanding on the content. So if you decide to just try yourself in aquarism, buy the most simple, but multi-colored gupashek.

They will delight you no less than the selection forms, but they will live much longer and have fewer problems. And for the pros, there will be breeding forms of guppies - they need to be carefully sorted, more carefully planted and cared for.

Feeding guppies

It is very easy to feed them, they eat very different foods - artificial, frozen, live, even dry. They eat flakes, granules and other artificial food with pleasure, but it is better to choose well-known brands, such as Tetra. From the living, the best is to eat the bloodworm, the pipeker, the brine shrimp, the cortex. It is important to remember that the guppy has a small mouth and stomach, the food should be small, and it is better to feed two or three times a day, in portions that the fish eat in 2-3 minutes. Guppies also love food with a high content of plant substances, so that their digestive tract remains healthy, and their immunity is high, buy in addition to the usual flakes, even with herbal supplements and feed them twice a week.

Separately, I want to say from dry food - this is not branded food, but dried daphnia, which is often sold in bird markets. I strongly advise you not to feed fish with such feed, even gupeshek. He is poor in vitamins, nutrients, and in fact it is just a dried shell. It inflames the digestive tract in fish and they die.

Guppy content in the aquarium

Like all tropical fish, guppies love warm waters (22–25 ° C), but can live in the wider limit of 19.0–29.0 ° C. As for the parameters of water, for ordinary forms it is almost irrelevant. They adapt to local conditions so quickly that they can transfer to a new aquarium without any problems at all. It would be ideal if the aquarium will have: 7.0 - 8.5, and a stiffness of 12.0 - 18.0, but the parameters can be completely different, which will not prevent the guppy from living and breeding.

The aquarium may be small, 20 liters will be enough for 5 fish. But, the greater the volume, the greater the number of fish you can keep and the more beautiful it will look.
It is best to have a lot of plants in the aquarium, as this will be similar to the natural habitat and will significantly increase the survival rate of the fry in the general aquarium. Lighting can be any, from bright to twilight.

It is advisable to use a filter, for gupeshek quite internal enough, but if there is an external one, then great. Only it is better to close the holes in it with an additional small net, since a powerful filter is not only capable of sucking the fry, but even an adult fish.

Guppies cannot be called a schooling fish, but there is almost no point in keeping it with a pair. It is very small in size and in small quantities is almost invisible in an aquarium. For guppies, the rule is simple - the more there are in the aquarium, the more impressive and beautiful they look.

Compatible with other fish

Very peaceful fish that does not cause any trouble to the neighbors. But it can be offended, especially large and predatory fish, which gupeshek perceive only as food. So with fish like slaughter, giant gourami, pangasius or shark ball it is not worth keeping.
It is also impossible to keep with fish that can tear off male guppies with fins - Sumatran barb, Denison barb, fiery barb, some gourami, such as kissing, with ternitsemi.
Guppies get along best of all with peaceful and small fish: - rastori, cardinals, congo, neons, cherry barbs, speckled catfish, tarakatum.

Gender differences

To distinguish the female guppy from the male is very, very simple. Males are smaller, slimmer, they have a large tail fin, and anal turned into gonopodias (roughly speaking this is a tube with the help of which males of viviparous fish fertilize a female). The females of the guppy are larger, they have a large and noticeable belly and usually they are rather pale colored. Even juveniles can be distinguished quite early, as a rule, those of the fry that were first to be painted will be males.

Plain female guppy

Guppy breeding

One of the easiest fish to breed is homemade guppies; they very easily breed in home aquariums. The fact is that they are viviparous, that is, the female bears her calf in her stomach, and a fully formed whitebait is already emerging. The first hours he will lie down and hide, but very soon he will begin to swim and eat.

To breed guppies you need ... a male and a female. Even not so, one young and active male will be enough to care for 3-5 females without getting tired. That is, for successful breeding it is possible to contain one male for 3-5 females. It is possible and more males, as males do not fight with each other, but only compete. You will see how the male tirelessly pursues the female, but this is normal and nothing needs to be done about it. The fact is that during such harassment, he fertilizes the female and soon you will have fry.

What do you need for guppies to breed? Fresh and clean water, good and abundant feeding and a pair of heterosexual fish. As a rule, guppies are quite successfully divorced in the general aquarium. But, they also eat their fry, and the neighbors, if they eat will help. This means that pregnant females should be planted in a separate aquarium.

How to understand that you have a pregnant guppy? In a pregnant female, the spot near the anus begins to darken, this is already visible to the eyes of the growing fry, and the darker it is, the sooner she will give birth.
Set mummy in a separate aquarium, with the same water and thickets of plants, where the fry can hide from her (yes, she can eat her children). When the time comes (maybe up to a month if you hurry to drop it off), she has no problem giving birth.

A female with a dark spot - soon!

Immediately after giving birth, the female must be besieged. Taking care of guppy fry is quite simple, as well as about parents. What to feed the guppy fry? You can feed them finely branded flakes (which you feed your parents), but better with dried egg or branded fry feeds. Note that there is such a relic of the past as dry food. It is dried daphnia and cyclop, it can still be found on sale. So, feeding this rubbish guppy fry is strictly not recommended. Nutrition there is slightly higher than zero, in fact it is an analogue of taranka. Will you grow up much if you eat one taranka? The same can be said for adult fish.

It is necessary to regularly clean them so that the rest of the food will not spoil the water. You can also run snails in this tank, such as an ampoule or coil. They do not touch the fry, and the rest of the food will be eaten.

How the fry is born:

It is important that the water was clean, but it is impossible to change a lot and immediately, since the fry are still weak and a large water change is dangerous for them. The easiest way is to change the order of 10% of water once a day or two, or 25% once a week.
Water temperature for guppy fry is very important, and you need to keep it at the level of 24-26.5С.
With proper care and feeding, guppy fry grow quickly and within a month and a half they begin to stain.

Frequently asked questions about guppies

What kind of fish can you keep with a guppy?

Some species have already been listed above, but you can still see the article - the 10 best fish for beginners, everything on this list is good for keeping with guppies.

How to find out that guppies are pregnant or about to give birth?

Usually, the female guppy gives birth to fry once a month, but the timing may vary depending on water temperature and conditions of detention. Note the time since the last time she gave birth, and watch. The female is ready for new genera, the stain becomes darker, it is visible the fry eyes.

How do guppies breathe?

Like all fish - oxygen dissolved in water, do not forget to include aeration and filtration.

How long do guppies live?

About two years, but it all depends on the conditions and temperature. The higher the temperature of the water, the shorter their life. Some fish live up to 5 years.

How often to feed a guppy?

Daily, and in small portions two to three times a day. For example, in the morning and in the evening. Once a week, you can arrange a hungry day, but keep in mind that the fish will actively look for food and the first victims will be their own fry.

Why do guppies tear their tails?

There may be a lot of reasons, but the most common is old water, which is rarely replaced. It accumulates ammonia and nitrates, and they poison the fish and destroy the fins. Regularly change the water to fresh. There may also be a sharp change of water, injury or poor feeding, when there are few vitamins.

If the guppy has lost its tail, then this is an alarming sign - either someone breaks off its tail, and you need to carefully study the fish with which it is kept, or it has become infected with an infectious disease, and you need to look more closely at the rest of the fish.

Why do guppies stick to their tail?

Again, either old and dirty water, or an infection, or scant feeding. Try changing 20% ​​of the water once a week and watching the condition of other fish.

Why does the guppy have a spine curve?

Such fish are found in almost all species, as a rule it is a defect from birth. If this happens in adult fish, then this may be due to the fact that it is contained in too close an aquarium, with a large number of fish. In guppy, the spine curls in the same way from old age, and this is normal, but the most frequent cause is fish tuberculosis or mycobacteriosis. Заболевание сложное, и лечение его не просто, не всегда приносит результаты. Во избежание распространения инфекции, таких рыб лучше изолировать.

Почему у гуппи рождаются только самки?

Точного ответа на этот вопрос не найдено. Apparently with an excess of males, the laws of nature are included and the population compensates for the females in order to preserve itself.

Is it possible to contain only one guppy in an aquarium?

It is possible, although it looks like something sad ... All the same, this is a cheerful and brisk fish that loves company. If you are looking for a fish that would be beautiful, unpretentious and live wonderfully, then look towards the rooster.

Do I need oxygen and a filter for guppies?

Not required, but desirable. You can buy an inexpensive, internal filter with a washcloth. It will perform its functions well enough and will not suck the fish into itself. Consider that if you bought a filter, and it is set higher (so that the surface of the water in the aquarium is in motion), then you will not need to buy additional aeration or simply put oxygen.

Do guppies need soil and plants?

This is your choice. An empty aquarium is easier to clean, but it looks worse, the fry cannot survive in it, and the gupies themselves love to frolic among the plants. I am for an aquarium with soil and plants.

Do you need a guppy light?

No, the fish do not need light at all, except that it falls on the aquarium during the day. Plants need light to grow.

Guppies spawn?

No, they are viviparous. That is, the fry is born completely ready for life and can immediately swim. Sometimes it falls in the egg, but it breaks and it floats. Sometimes he has a yolk sack, which he quickly assimilates.

Do guppies sleep?

Yes, but not like people. It is rather an active holiday, when at night the fish reduce activity, but still swim. And it is better to turn off the lights at night, although some do not, but is it dark in nature at night?

How many fry do guppies give birth?

Depends on the female, her age and size. Usually about 30-50 pieces, but sometimes 200

How much does a guppy fry grow?

Very fast in good conditions. Males become mature in two months, and females in three.

Can guppies be kept in seawater?

No, they tolerate poorly salted water, but they die in the sea, this is a freshwater fish.

Why do guppies float on the surface?

They breathe oxygen dissolved in water, and in your aquarium it is not enough. Because of which? Maybe it’s too hot, maybe you haven’t cleaned the aquarium for a long time and didn’t change the water, perhaps too closely. Be sure to turn on aeration or filtration (place the filter closer to the surface of the water to enhance gas exchange) and replace some of the water with fresh one.

Why do guppies jump out of the aquarium?

They can do it both by chance and because of bad water - for example, if it has not been changed for a long time and the soil is not siphoned in the aquarium. Also, the reason may be a small amount of oxygen in the water, read about it above.

Why do guppies stick together or stick together?

Unfortunately, the exact cause can not be named, even if the aquarium is near you. This may be improper feeding (monotonous, only dry food or abundant), there may be unsuitable water parameters (a lot of ammonia), and there may be a disease. The minimum that needs to be done is to replace part of the water, siphon the soil and change the type of feed.

What kind of catfish can you keep with a guppy?

Any small. More or less large catfish, almost without exception predators. The only exception is tarakatum, it can be contained with guppy. Well, any corridors, for example speckled, will get along superbly with guppies and will be very useful, eating the rest of the food from the bottom.

Care for guppy fry

The most unpretentious of the fry, survive in the wild. But, if you regularly change water, feed so much that they eat in a couple of minutes and feed the fry two or three times a day, they will quickly grow, color and please you. What to feed the guppy fry? There are no difficulties in feeding, they eat crushed flakes, but it is better to give Artemia naupilii or shredded strawberry.

About breeding guppy fish

Guppies - viviparous aquarium fish. Bright, beautiful, miniature, they are characterized by endurance, a wide range of conditions of detention. And most importantly - the selection of guppies does not present any difficulties. They willingly breed in captivity, without requiring special conditions. However, in order to seriously master the breeding of guppies, it is necessary to have information about the features of their reproduction, to understand how to care for fry.


Guppies grow quickly and mature: by three months, as a rule, they are ready to produce offspring. It is very convenient that the males of these fish are different from the females - they are smaller, slimmer, brighter colored. In addition, they have a pointed and coiled anal fin - gonopodia, which plays an important role in reproduction. The female is larger, with a short tail fin.

These fish belong to viviparous. The female does not lay eggs, but gives birth to live, fully formed fry, ready for independent living.

Spawning, preparing an aquarium

Spawning guppies does not require special conditions. But, if you still need to stimulate it, it will be enough to add fresh water to the aquarium a little more often and raise its temperature a couple of degrees. How many fish do you need for breeding? Enough couples - male and female. If you keep a flock, then one male is enough to care for 3-6 females.

Fertility of guppies occurs with the help of a male's modified fin - gonopodium. He is able to take different positions and with his help the male guppy directs seminal fluid into the female.

A guppy's pregnancy is determined by a gradually darkening spot near its anus. Also, of course, the pregnant guppy is getting fat - her belly is gradually increasing. Pregnancy lasts 20-45 days.

Interestingly, single fertilization is enough to ensure that guppies give birth several times. Fry guppies ripen in batches, so birth after mating often occurs - once a month and a half for 3-4 months.

Usually, guppies breed so actively and without problems that they are not deposited in a separate container. The number of fish is controlled naturally - larger fish eat them. If it is important for you to keep the guppy offspring, then it is worthwhile to plant a couple in a separate aquarium and provide them with good care. The main condition of spawning equipment is the presence of lush greenery where fry can hide. After the end of childbirth, parents from babies should be transplanted, as guppies eat their fry.

It is important to take into account one more thing: uncontrolled closely related interbreeding in the offspring causes the manifestation of various external defects, pathologies, weakens their immunity. Therefore, breeding guppies deserves attention.


How many fry a female can produce at a time depends on her size and development. Young on average bring 20-25 kids at a time, adults and large fish - up to one and a half hundreds.

Guppy fry are born very tiny, it is often difficult to see them. Their translucent, grayish coloring, against the background of which only dark eyes stand out, plays a big role in this. The young actively grow, and already after 30-40 days of life they begin to gain "adult" coloring, their gender begins to be determined. At the same time, it is worthwhile to transfer them from a spawn (if they were kept there) into a larger volume.

Special care for babies is not required. What to feed the guppy fry is very easy to determine. The main thing to consider is the size of their mouth. Food should be small enough so that miniature fish can swallow it. You can use specialized feed for juveniles or pounded daphnia, gammarus, Cyclops. Some experienced aquarists offer in the form of food for the first time mashed boiled egg yolk and steep yogurt. Keep in mind that the remnants of such food should be immediately and very carefully removed from the aquarium - they instantly rot and the water can deteriorate. Than to feed guppies fry when they grow up, it is also easy to decide - with the usual food that you use for all other fish.

The kids are transplanted into the general aquarium when they grow large enough not to be eaten.

Guppy Selection

The simplicity and speed of reproduction, easy care make the selection of these fish very fruitful. Even a beginner aquarist, with due patience and information on how to breed guppies, is able to breed a new interesting breed.

The most important thing in breeding is to avoid inbreeding, that is, closely related crossbreeding, which can negatively affect offspring. Therefore, for breeding, it is optimal to use three pairs of producers at once, which are contained in separate containers, and their progeny crossbreed.

It is also important that in females selected for breeding, the first spawning takes place exactly with the producer you need. There are cases when guppies continued to give birth within a year after mating. Therefore, the use of "virgin" females guarantees you the desired line of offspring.

But even if you do not aim at breeding a new breed, it is still worth controlling reproduction. Otherwise, in a few years, in your aquarium, instead of spectacular pedigree fish, there will be a flock of gupashek with an indistinctly variegated or wild, nondescript coloring and defects of degeneration.

Guppies are really worth it to do. Common and unpretentious, they are nonetheless not at all ordinary. Bright pedigree gupyashki not give way to showiness representatives of the most exotic and capricious aquarium species. And the breeding of these pets - a truly exciting and creative activity, which, moreover, does not require much effort.

How neon fish breed

The reproduction of neons is not so difficult in the conditions of a home aquarium, if you follow a number of requirements. First of all, you should know that in the wild, spawning of neon fish occurs during the rainy season, and lasts 1.5-2 months during the year. When spawning ends, the fish calm down and take a break. Neons brought into our country can breed at any time of the year, which simplifies their breeding. A variety of live food, replacement of aquarium water stimulate their mating season. You should know that all types of neons (blue, blue, red, black and others) are not viviparous, but ringing fish.

How does the reproduction process in neons

Aquarium neons should spawn under careful supervision - due to changes in the natural rhythms of life, laying eggs can be endangered. All males and females must be transferred to different reservoirs, and before being placed in a general spawning ground, a short “acquaintance” between the fish should be carried out 5 times. The neon female can lay eggs every week, and the male can produce milk 2 times less. Sexual dimorphism is expressed during the breeding season - females are rounded in the abdomen, the swimbladder excretes in males, it shifts to the anus, which is not present in females.

Before the spawning device, prepare the water - take the water from the tap, let it infuse for several days in a glass container, then heat it to the required temperature. The optimal parameters of the aquatic environment will ensure the fertilization of the maximum number of eggs, and their ripening. Aquarium for spawning, you can choose the average - 30-50 liters per pair. It is not necessary to line the bottom at its bottom. Allowable water temperature in the tank: 25-26 degrees Celsius, hardness 2-4o, acidity 6.5-7.0 pH.

See how to prepare an aquarium for breeding neon.

Successful breeding will provide the substrate in the form of aquatic plants. At the bottom of the tank you can put a few sprigs of miriofillum or javanese moss. It is better to launch fish that are ready for spawning to the aquarium in the evening, a few hours before turning off the light - so the pair will get used to each other faster, and in the morning the caviar will be swept up.

Aquarium fish, despite the fact that they are contained in different conditions of the aquatic environment, unlike natural relatives, behave in this process in a similar way. Two males are usually run on one female, and they instantly attack her, and the male who is faster than the opponent, wins, it fertilizes the eggs thanks to the highest degree of readiness. Prior to the spawning process, males and females float above the plants. Then she puts her eggs on plants in a chaotic manner.

The first few hours after spawning, the eggs have an adhesive texture. Once on the plant, they are fixed on them, and then, with a slight fluctuation of water, fall to the bottom. Therefore, it is impossible to line the soil in the tank - the substrate can damage their thin surface. 3-4 hours after the breeding process, the male and female are caught from the spawning net with a net, and if this is not done immediately, then the producers can eat their fruits.

How to care for brood

Unfortunately, not all fertilized eggs can survive, some can get a fungus, and some will die during the ripening period. After 9 hours, surviving, unspoiled fertilized eggs can be selected from the rest with a medical pipette. Transfer them to another container with similar parameters of water so that they do not get infected and die.

Watch a video on how to care for neons and how fish breed.

The most dangerous enemy of neon eggs is harmful bacteria and fungus. With the help of drugs Trypaflavin, methylene blue or General Tonic, you can stop the reproduction of microbes, thereby ensuring the life of future fish. After adding the drug, the water level can be reduced by 7-10 cm. Caviar will ripen until the larvae appear. This will happen in 24 hours if the temperature of the aqueous medium is 24-25 ° C.

After a few days the fish fry can swim in the upper layers of the water, at the same time they can be given food that they themselves will eat. Starter food for fry - Cyclops larvae (for the first 4 weeks of life, until the first color strips appear on the body). If you know how to produce infusoria, rotifers or other types of plankton at home, you can add this feed.

The fish grow quickly, later they will require another feeding, now they can be given small cyclops, chopped live food. When the brood grows up, the surviving fry can be moved to another aquarium with a temperature of 24-25 degrees, water hardness of 10-12 o. This is necessary so that they are not infected with plistofora. At first they will adapt to the new conditions, in a month they will get used to them completely. If the water is too hard (take measurements with devices with indicators), soften it with special tools that are in stores.

Guppy gives birth

Breeding guppies (Breeding Guppy).
Posted by: David Lass. (Translation: Leontev Sergey Vladimirovich) 10/14/2006
Guppies are prolific fish, that is, about every 30 days, the female brings fry, which are miniatures of their parents. In the general aquarium with other fish species or with adult guppies, fry become easy prey for adult fish.
If you have a lot of floating plants in the aquarium, then some of the fry will most likely survive, but if you want to save the entire fry, then the best way out is to transplant the pregnant female into a separate small aquarium. 20-40-liter is fine.
This aquarium can be planted with floating plants. Use a sponge (airlift) filter and heater (if needed). The female is deposited in a vessel only when it is possible to determine by the external signs a large period of her pregnancy, otherwise premature labor can be provoked.
I do not advise you to plant guppies in those small plastic inner mesh holders, because, in my opinion, they cause great stress to the fish. The grid fixed among plants is an extreme case if there is no separate aquarium.
If the female becomes pregnant once, she will almost always be pregnant. Even without the presence of males, the female guppy brings the following litters, using the sperm of the male, with which he mated before, which is stored in her.
"Fish of millions" (this is the old common name for guppy) can have a huge number of descendants in a very short time. Consider that the female guppy can become pregnant at the age of two or three months. Each pregnancy brings from 20 to 50 fry. In two or three months, these fry will bring 20-50 descendants themselves, and so on. If you count, then make sure that in the very near future, you will become the owner of a huge number of guppies.
A word of caution should also be said here about local pet stores: it is virtually impossible to guarantee that you will acquire a clean guppy line there (that is, all babies will look like their parents). Females are usually sold after they have already brought several litters of fry. Males are bought in different places in bulk. The fish in the pet store is mixed, and for guppies, this means that the purity of the line is impossible, since any male can fertilize any female.
After several generations of random matings, guppies will become similar to their wild ancestors and will no longer be able to boast of their fin sizes and color acquired due to long years of selection. If you want to get a clean line, then it is better to buy fish from qualified breeders who advertise their fish on the Internet and specialized magazines.


That give them a month to be together, they will drain the kids for you ... it's hard, only if you notice that they are starting to mate, change the water in the aquarium, because the little gupps are like xs who are still small, even when you look at them you will see, just change it so as not to change after they appear ... here we had about 20 kids from one pair ... we counted that only, and don’t know how to sell, probably more
