❶ How to breed fish :: aquarium fish breeding video :: Aquarium fish

Every aquarist wants the fish to live in the aquarium for a long time and successfully multiply. To do this, your pets will need not only the attention of the owner, but also special conditions.

The question “opened a pet store. Business is not going. What to do? “- 2 answers

  • Spawning aquarium
  • Plants
  • Directory of fish species
  • Ceramic pots, tree roots, nylon filament, broadleaf plants – depending on the type of fish
  • Pipette

1. Decide what kind of fish you are going to breed. They are viviparous and sleeping off.

Viviparous produce viable fry into the world, and their reproduction usually does not require special conditions. A single fertilization is enough for a female to produce fry 7-8 times.

At the same time she has several dozen fry in one litter.

2. Select a pair of producers, the largest and correctly folded female and male. Pay attention to the color, it should be the brightest of all the available fish.

Set the manufacturers in a separate aquarium.

3. When the fry appear, separate the parents and offspring. Fry immediately begin to feed them with small cyclops. As a feed for newborns suitable live dust.

Periodically give finely grated egg yolk.

4. With the growth of fry change their diet. Let’s Cyclops larger, daphnia, bloodworm.

5. Prepare spawning fishes for spawning. Each species spawns differently.

It is necessary to take into account the temperature and thickness of the water layer, its composition, oxygen content. Determine the size of the spawning area and the substrate to be put in the aquarium, the number and types of plants,

6. Plant the spawners in a spawning tank. Matrimonial games begin with the fact that the female flirts with the male.

Then their roles change, the male pursues the female. Then the female lays eggs, and the male fertilizes them.

7. After fertilization, seed the growers, as many species of fish eat their eggs or fry. Remove unfertilized eggs from a spawning aquarium with a pipette, otherwise it will rot.

Caviar develops from 2-3 days. There are species of fish whose development of caviar has a longer period, from 10 days to several months, and even up to six months.

After that, the fry hatch from the roe.

8. Feed the fry with live dust. When they grow up and become only half the size of adult relatives, transplant them into a common aquarium.

The aquarium for the relocation of the producers of viviparous fish should be planted with leaf, peristolenic and other aquatic plants. The vegetation should be fairly dense, since adult fish often eat fry.
Fry of various viviparous fish reach sexual maturity at the age from two to ten months.

Instead of separating parents and offspring, you can plant a female in a spawning basket before giving birth. The basket should have holes in which the fry can swim. –
Artemia and micromin are also suitable for feeding fry.
If you have prepared an aquarium for spawning short-fish, and they are not in a hurry to engage in love games, try changing a little the temperature or composition of the water. But the change should not be very significant, otherwise the fish may die.
Before spawning, you can hold for some time manufacturers in different aquariums. A signal to the mating games will be their connection.
Living dust is infusoria, rotifers, small cyclops, and so on. If there is no live food, you can use micromini and egg yolk, but this is at the very least.
To stimulate reproduction, feed fish with a variety of foods, especially important for a fortnight-month before spawning.

Reproduction and breeding of goldfish

in aquarium

Goldfish is one of the most ancient aquarium fish. Their story begins with the first century of our Era and Ancient China.

Even then, the emperors of the East and Buddhist monks began to maintain, breed and select goldfish.

Actually, therefore, at present there are a great many aquarium goldfish, and their cost can vary from 2 dollars to several thousand US.

So, if you want to feel like a true goldfish breeder, emperor or Buddhist monk, then this article is for you!

Breeding or breeding goldfish, is not a difficult task.

However, goldfish are not guppies and in order to get offspring you still have to work hard and be patient. In addition, you need to have a sufficient number of aquariums or ponds.

One aquarium will not get off!

Goldfish breed independently, without any hormonal injections or without creating too specific conditions. Actual, good maintenance and proper feeding is the criterion and incentive for spawning producers.

All types of goldfish can spawn in aquariums of a small volume of 30 liters. However, better results can be achieved in larger aquariums or in ponds.

Spawning of goldfish can occur at a temperature of 16 degrees Celsius, but it is better to maintain the temperature of the aquarium water at a level of 22-24 degrees Celsius. After replanting manufacturers increase the temperature by 2 degrees.

The water level in the spawning pond should be 20-25 centimeters, the water should often be replaced by fresh and purged.

Unlike many other spawning aquariums, spawning for goldfish should be well consecrated all light day. If it is a pond, then the sunlight should be diffused, and the pond should be equipped with shelters in the form of floating plants.

Producers are planted in a spawning aquarium in the ratio of 1 female to 2-3 males and richly fed with live food (bloodworms, earthworms, daphnia, ground meat with bread, etc.). At the same time they try to select manufacturers based on their size.

Especially females – the bigger they are, the more eggs they sweep out. And vice versa – small females toss less eggs.

They equip an aquarium with vegetation (such as a combo, riccia, duckweed, a peristist, etc.), and do not carpe the bottom of the aquarium – on a clean bottom the eggs retain and do not die, but some aquarists set up a separate grid. Sexual maturity in fish comes to a year of life.

In this case, the males appear on the gills white bumps and the so-called “saw” on the front paired fins, and the females are growing stout, their body is bent. For more information, see: HOW TO DETERMINE THE FLOOR OF A GOLDEN FISH: A male and a female!

A female matured for breeding emits a special substance that has a characteristic odor and is particularly concentrated in the genital organs. Actually, this smell attracts males and is a signal of a female’s readiness for reproduction.

Under the influence of this secretion males begin to swim for females.

Under pond conditions, it is recommended to perform the above spawning manipulations in March – April, with the expectation that spawning will begin in May – June. It is believed that this is the most prosperous time for the successful ripening of caviar.

In addition, at this time it is easier to provide the eggs and fry with the necessary comfort.

If the courtship of the males began earlier than March – April and the spawning should be delayed, the producers are seated and also the water temperature is lowered to the desired period (period).

The peak of reproduction of goldfish is accompanied by violent courtship of the males – they chase the female around the reservoir, and on the day of spawning, these courtships look like a frank pursuit.

Taking into account such features, the spawning aquarium is equipped with soft aquarium plants and not sharp decor (it is better without it at all). Otherwise, the fishes will sweep, and their fins will be torn after spawning.

The spawning begins with the first rays of the sun and lasts 6 hours. Spawning gold can every month until October. During one spawning, the female can sweep up to 3000 eggs.

In the “home” spawning of goldfish can sometimes occur continuously – year-round. However, this leads to the exhaustion of manufacturers, and in this case they should be given rest, seated in different aquariums.

Photo Caviar Goldfish

Caviar ejection occurs gradually. – the female driven by the males touches the vegetation or the walls of the aquarium and releases 10-30 eggs, which the males immediately fertilize – watering the eggs with milt.

Then, sticky caviar falls to the bottom or sticks to the plants.

Eggs on the first day are slightly orange and slightly flattened, the diameter of eggs is up to 1.5 millimeters. On the third day, the eggs are straightened and discolored, in connection with which they are difficult to detect.

Immediately after spawning, the producers are removed from the spawning tank, otherwise the offspring will be eaten.

The water level in spawning caviar is reduced to 10-15 centimeters and protected from overheating and excessive sunlight (if it is a pond). Aquarium intensively aerated.

The appearance of fry from caviar depends on the water temperature. At a water temperature of 22-24 degrees Celsius – the incubation period is 4-5 days, but at a temperature of 14 degrees Celsius it can reach 7-8 days.

On the second day after the appearance of the young in the aquarium, it is recommended to launch snails (for example, coils) so that they eat the dead and not fertilized eggs. You can carefully assemble yourself, but it is more difficult than it seems.

It is very important not to kill the young. At the same time, leaving the dead calf is fraught with – live larvae do not tolerate “dirt” and can get sick.

Young goldfish in the first days is weak and harmless, in fact it looks like a reed with eyes and a yolk vesicle in the middle (the yolk bubble is necessary for obtaining nutrients in the first days of life). Fry move in spurts and can stick to the stop.

After about 2-3 days, they begin to blithely float around the reservoir, and from this point on, the young need to be fed with starter feed: live dust, the finest alga, and other finely ground to feed dust. After 2 weeks, you can give larger feed. At the age of one month, juveniles are capable of taking small bloodworms. As a starter feed, they also use egg yolk finely ground in water, as well as the soaked oatmeal grated in the dust.

The fry are fed abundantly, but in portions – little by little but often.

We can recommend the following feed for young goldfish.

JBL GoldPearls mini is premium class granules, packaged in 100 ml.

It has a special recipe ideal for young fish. The diameter of the granulated feed 1-2 mm.

Contains spirulina and carotenoids, which contribute to the development of good fish color, contain proteins (10%) from wheat germ, fatty acids.

After two weeks the fry are planted in a 30 liter aquarium at the rate of 250 fry per aquarium. Aquariums flush or replace water frequently. Without purging, it is recommended that 120 fry be planted per aquarium.

So they contain up to 2 months of age, gradually sorting by size and reducing their number. Fry are caught not with a net, but with a saucer or other utensils.

So they are easier to get and count.

Photo spawning hotbed for goldfish

Sorting carried out on the principle of rejection. Harvested juveniles with defects, juveniles lagging behind in growth, etc.

In the end, get pedigree goldfish.

Defective and non-standard young, unfortunately kill. First, because it, as a rule, does not survive itself, and secondly, even if it survives, nothing good comes out of it.

With its further content, you risk getting outbred offspring “bastards”, but if you go further, then the fish just degenerate into a silver carp.

At first, the scaled juveniles of goldfish have a silver-gray color, like the progenitor of the goldfish. Coloring appears only at the age of 3-5 months.

To improve the brightness of the fish color, it is recommended that “sunbathing” light should be diffused. In an artificial reservoir, no shading is necessary, on the contrary, the aquarium is intensively illuminated with lamps.

It is worth noting that the color of goldfish can vary in fact a lifetime.

Scaleless fry do not pass the aforementioned period of silver color and already at two weeks of age begin to turn into their final color.

Juveniles of goldfish are very capricious and prone to disease. To avoid mortality of offspring, you should regularly monitor the cleanliness of the aquarium, aeration and filtration.

Constantly monitor the population – do not forget to settle as they grow.

When breeding goldfish need to strictly observe the species crossing. All goldfish can interbreed with each other (for example, veil tails with comets).

Summing up, you can make a short list of what you need for breeding goldfish:

– one year old males: 1 female, 2-3 males.

– Aquariums: the main from 150 liters, spawning from 30 liters, aquarium for youngsters; (aquariums should be illuminated).

– aquarium soft-leaf plants;

– of course: aeration, filtration, thermostat;

– feed for fry;

– improvised aquarium equipment;

Swordtail Aquarium Fish Diseases There are three main reasons:

  • wrong content;
  • bacterial and fungal infections;
  • parasites.

You would think that only in the first case the fault lies with the aquarist’s conscience. But in fact, infections and parasites affect fish with immunocompromised.

In other words, even if there is no fungus or parasite in the aquarium, in bad conditions the fish will get sick.

Attentive owner will notice the beginning of the disease Swordtails with daily inspection of aquarium fish. That’s what it costs note:

  • fading in place, lying on the bottom;
  • random swimming, rocking, rubbing against stones;
  • loss of appetite;
  • bloating;
  • folding fins;
  • dull and whitish spots on the body;
  • cotton-like shreds.

The diseased individual should be transplanted as soon as possible. It may be possible to save the healthy from infection.

Seaweed Siamese DESCRIPTION

Siamese algae (Latin Crossocheilus siamensis) is often called CAE (from the English Siamese Algae Eater).

This peaceful and not too big fish, a real aquarium cleaner, tireless and insatiable. In addition to the Siamese aqueduct, there is also a species Epalzeorhynchus sp (Siamese flying fox, or false Siamese seaweed) on sale.

The fact is that these fish are very similar and they are often confused. Most Siamese algae-eaters that are on sale are still real, but there are often cases when both real and false algae are sold together. This is not surprising, because in nature they live in the same area and young


it forms mixed flocks. How to distinguish them?

  • Differences between the present and the false, or chanterelle:
  • the black horizontal stripe running through the whole body, in this seaweed continues on the caudal fin, and the false do not
  • the same strip in this goes zigzag, its edges are uneven
  • the false seaweed has a pink ring
  • and he has two pairs of mustaches, and this one has one and it is painted black (though the mustaches themselves are barely noticeable) Now you ask: what is the difference? The fact is that the flying fox eats algae somewhat worse, and more importantly, it is aggressive towards other fish, unlike the Siamese algae. Accordingly, less suitable for general aquariums.

Algae eaters are famous for their jumping ability and supermobility, so they need a lot of space in aqua – at least 100 liters per pair. There should be enough vegetation so that the fish can find shelter (they really like algae with wide leaves).

The tank should be equipped with a cover glass or an adjacent cover so that the algae could not jump out of the aquarium. At the bottom you can put small gravel or large non-sharp stones, snags.

For the Siamese algae, the content necessarily involves very clean water, which must necessarily be enriched with oxygen. Therefore, be sure to purchase a filter with high power, organize a constant aeration and substitution of up to 30% water. In the aquarium, you can arrange and flow, although it is not necessary.

CAE is not particularly demanding on the parameters of water – the optimum temperature is 24-26 ° C, the hardness is 5-20 dh, the acidity is pH 6.5-7.0. Lighting can be both muffled and bright – for fish it is, in general, indifferent.

The main part of the CAE diet is algae, but if this food is not enough, then the fish willingly eat any live and dry food. However, it is required to feed the seaweed and vegetable food (green food), otherwise they may start to eat mosses and other useful plants in the aquarium.

Please note that you should not keep these fish in the aquarium, where there is Javanese moss – this is their favorite food, so nothing will remain from moss in this case.

Fish breeding is difficult to distinguish by sex, but there is one difference. Algae-eater is a bit more complete and looks rounded when viewed from above. In artificial conditions, the Siamese Epalceorinhus reproduces exclusively by hormonal means.

In the wild, the fish pass through reproductive seasonal migrations. During a drought, they move upstream, and when the water level rises – in the opposite direction.

It is natural to assume that with the Siamese algae you will spawn when the quality characteristics of water (temperature, hardness, pH level) and other conditions of keeping change.

Cardinal fish: compatible with other breeds

Optimal conditions for the flocks of good-natured small cardinals – a separate aquarium. There they will be most comfortable.

It is very interesting to watch their quiet games, and to multiply and behave in a calm atmosphere, the cardinals will be clearly more active. Calm and funny fish cardinals are too peaceful.

They can be offended by representatives of aggressive breeds. Dangerous neighborhood with predators such as astronotus, piranha, barbus, angelfish, goldfish.

It is necessary to take into account the lack of agility of the Cardinals. Even quite peaceful inhabitants of the aquarium, the size and strength of which is greater than that of these fish, will be their serious competitors in the division of food and territory.

Lack of food or a comfortable place will affect the general state of health, the ability to reproduce, the appearance of the cardinals. If you still want to observe the diverse inhabitants in your glass pond, you can look at guppies, fiery tetras, danios, rhodostomusam, crescents, neons, honey gourami, corridors, glass perches or shrimps.

Despite its unremarkable size, the cardinal is a bright and colorful fish with an elongated and slender body, which is slightly flattened in front, on the sides. On top of the muzzle – a small mouth, which is located as in nature, it collects insects from the upper layers of water.

The fish has no antennae, the dorsal fin is in line with the anal fin.

Color bronze brown, with a bright strip passing through the axis of the body. On the tail there is a bright red spot, part of the tail is transparent.

The abdomen is lighter, in contrast to the rest of the body, the fins are slightly veiled, also colored in raspberry red. There are artificially derived colors, even albinos.

When the fry reach a length of 4-5 mm, a shiny silver-blue strip appears on their body, which disappears when reaching a length of 2-3 cm, that is, upon reaching puberty. Males are slimmer and more elongated than females, the differences between them are mild.

The nature of the aquarium fish active, mobile.

Cardinal (fish) – fish of the carp family, of the class Ray. The name got its due to the desire of easy money merchants, who hoped that it would be better sold for industrial purposes.

The Latin, classical specific name is more euphonic: “alba nubes”, which literally translates as “white clouds”. For the first time these fish were found in China.

cardinal fish photo

In Guangdong, China, in 1930, the leader of a pioneering movement named Tang Meng Yo made the first entries about cardinals. In the description, it was stated that this fish survives well in water with a low temperature, and, as it turned out later, aquarium conditions for it are also not a bad place.

Later it was sold under different names, and the “cardinal” was not the only one. Chinese danios, false neon, magnificent minnow – such names are often found on the market.

The fast south Chinese rivers are the natural habitat of the cardinals. Keeping and breeding them is available only in aquarium conditions, since they are almost wiped out in the wild.

Since the 1980s, there has not been a single notification about the places of their population. In China, this species was temporarily considered extinct. Miraculously, it turned out that a small school of fish was found in some Chinese and Vietnamese provinces.

All fish sold today are bred.

Gourami (Trichogaster) – one of the most popular types of aquarium fish today. They are unpretentious in content and are quite easy to breed, these fish can be safely recommended to all novice aquarists.

Sphaerichthys osphromenoides

Chocolate gourami are found in Indonesia (Sumatra, Borneo) and Malaysia.

The body of the Chocolate Gourami has a red-brown or chocolate color, with a slight greenish tint. The whole body is crossed by several light yellow to white color transverse stripes of various widths and lengths. Anal fin with narrow yellow border.

The size of the fish does not exceed 40-50 mm.

The male has a straight lower jaw profile and has a sharper head than that of the female. In the female, the lower jaw is rounded due to tensile skin, due to the need to incubate the eggs.

But so familiar to all the differences in the form of bright colors and pointed elongated unpaired fins should not be relied upon to determine the sex.

Ghouls nagging

Trichopsis vittatus

Currently, most of Indochina, the peninsula of Malaysia and Singapore are settled.

The fishes are peaceful and slightly fearful. They can easily be kept in a common aquarium with other peace-loving fishes.

It is advisable to keep a small flock of 6-8 fish, in a ratio where there will be one or two females per male.

In captivity, the ghouls grumbling eagerly eat dried food, but do not forget to include in the diet a sufficient amount of small live or frozen food, such as Daphnia, Artemia or chironomid larvae (the well-known bloodworm), which will allow to achieve optimal color.

An aquarium with ghouls nagging densely planted with various plants, leaving room for free swimming. Since the fish do not like bright light, floating plants are placed on the surface, which serve not only as a source of dispersion of rays, but also serve as material for building a nest. Grateful fish will be for the presence of kryagi and a variety of shelters.

It is preferable to use dark soil.

Cardinals are considered to be peaceful and non-aggressive aquarium dwellers, which are recommended to be kept in flocks of 6-8. They get along well with ternetii, red neon, rhodostomusami and danios.

Basically, the cardinals are kept in the upper layer. You should not have any difficulties with keeping aquarium fish. Prepare a small aquarium, based on the proportion of 30 liters of water per pack of up to 7 pieces.

Make it the water level centimeters 25.

Aquarium soil can be used in the form of river sand, which must be processed before being laid in the aquarium. It is also possible to use small pebbles as a substrate.

It is also recommended planting aquarium plants, but not very thick. As a rule, they put an elodea, a people, a hornpole or a vallisneria into an aquarium.

The parameters of aquarium water in an aquarium with fish cardinals should be the following: hardness: 4-20, pH: 6.5-7.5, water temperature: 18-21 degrees. The aquarium requires filtration and aeration of water, as well as weekly changes of up to 20%.

Cardinals also like bright lighting, especially light is needed in the winter.

There is a cardinal live and dry food. Perfectly eats cyclops, bloodworm, dry daphnia.

In nature there is almost all the time small insects.

Breeding cardinals who, being in the general aquarium, are constantly malnourished due to inactivity, require special conditions.

Therefore, in the spring, 10-15 days before the intended breeding, males and females are deposited in separate containers. Otsadniki, where fish are constantly fed small live food, can be three-liter jars filled with fresh settled water, which is periodically aerated. The water temperature is maintained at 22-23 ° C.

The cardinals nest consists of two females and one male. In order to avoid any accidents, two nests are prepared for spawning.

The readiness of the fish is determined by the female, whose abdomen acquires a noticeable roundness.

Spawning for one or two nests can serve as a low aquarium from 10 liters of water. The bottom of the vessel is covered with a layer of well-washed coarse-grained river sand, about 1/4 of the capacity is taken away under small-leaved plants, such as perististolemum, golodniknik or nitella.

cardinal fish photo

The Ludwigius planted in the ground, Indian fern, and hygrophil are quite suitable. It is preferable to make water for the spawning area from “old” and fresh (separated) water, mixing them in equal parts, but you can also use fresh water. The water temperature is not lower than the one in which the fish were prepared for spawning.

Its level is small – 20-25 cm. The lighting is moderate.

The fishes placed in the spawning grounds immediately become lively, and the males begin their courtship ritual – make elegant turns around the females. When water temperature is up to 25 ° C, fish liveliness increases.

Spawning can last for two days. During this time, one female sweeps up to 30 eggs.

If you need to get a second after the first spawning, and they can be up to ten with 8-12 days breaks, the producers are again seated in different containers and heavily fed with live food. Stopping breeding, the fish are placed in a common aquarium with the usual feed and temperature regimes.

Incubation of caviar lasts from 30 to 50 hours depending on the temperature of the water, which should not be subject to significant fluctuations.

Cardinals’ larvae are so small that they are barely visible with the naked eye. The larval period, when these crumbs hang motionless on a particular substrate, lasts up to 2 days.

p> The fledged cardinal fry are fed without departing from table 2, but because of their small size, feeding with infusoria or other starting food is somewhat lengthened. The small size of cardinals, the peculiarity not to destroy their eggs and offspring, even in the larval stage, as if by nature itself predetermined their content in the aquarium separately from other fish. In the 15-20-liter capacity, you can create a miniature copy of the natural reservoir, observing all stages of life of these fish, without disturbing them with transplants to prepare for spawning and spawning.

The device of a specific aquarium for cardinals (it will also be a breeding ground for 3-4 nests of these fish) provides for the presence of sand and a small number of plants on the bottom. The only difference between such an aquarium and an ordinary breeding ground is that the water in it ages, acquiring an amber-yellow color, and therefore 1/5 of it should be replaced with fresh water every week.

Normally feeding, even with surrogate foods or dry feed, the fish, being in optimal temperature conditions for breeding, are occasionally ready for spawning without special training. This makes it possible to observe the “tournament battles” of the males and see their courtship for the females.

With hasty movements with flowing fins, males hover around females, periodically bouncing off to the side, rushing into the midst of plants, as if inviting them to follow them. When the efforts of the males bring success, the fish hide in the thickets of plants, where the spawning takes place.

Before the eyes go through all the stages of life of a miniature fairy underwater world. A hank of caviar lasts not 2-3 days, as during normal spawning, but about a month, since every day a female spawns only 2-3 eggs. Rest after such spawning lasts about a week or more.

After this, the normal life cycle begins.

The fry that have appeared in 3-4 days from the moment of spawning begin to feed, as usual, with small living “dust” or artificially grown culture of ciliates. Since, in contrast to the temporary spawning grounds, there are always a small number of ciliates and other aquatic organisms in a lived-in aquarium, feeding newborns in the first period of their life becomes easier – in one way or another, they find food.

If day by day the number of fry increases, then without adding starter feed is not enough.

cardinal fish photo

True, there may be a slight increase in the number of ciliates directly in the aquarium, if you provide them with food. For this, a thin slice of carrot or a small piece (1 sq. Cm) of banana peel is suspended on a stainless wire in the uppermost layer of water.

Getting wet and decomposing slowly (if there is aged water in the aquarium, but you should be afraid that it will deteriorate), they are a good environment for bacteria, and those, in turn, will contribute to an increase in the number of ciliates. After the first portion of the feed for the ciliates is completely decomposed, it will disintegrate, you can hang a new one.

The first fry, attracted by the abundance of small food in a certain place, remain there until this food ceases to satisfy them. In place of the grown-up fry (they go in search of a larger feed) come more and more new generations in need of an initial feed.

You can continue feeding juvenile cardinals on any surrogate feed, not excluding dry feed. Growth rate of fry naturally slows down.

And yet the fish eventually reach good size and full development, which allows you to get offspring from them.

Macropod fish care breeding description compatibility photo feeding

These creatures are very unpretentious. But if you let life in the aquarium take its course, then from paradise fish they will turn into faded unattractive fish.

If you do not want such a turn of events, it is better to try and create the most comfortable conditions for macropods. What is required:

Aquarium. Its volume for a couple should be at least 10-20 liters, and optimally – 40 liters. In small containers, these chordates can live without problems, they simply will not grow to their full size.

From above it is better to cover it, as the fish can jump out. The glass or cover should not fit snugly, as the macropods rise to the surface to breathe.

The recommended distance from the water to the cover is 5-6 cm.

Water should have a temperature of 20-25 degrees, a hardness of 5-25, an acidity of 6.5-8. Macropod can withstand short-term temperature jumps from 10 to 35 degrees.

If they are maintained not in the general aquarium, but separately, then aeration and filtration are not necessary. If there is still filtering, then a strong flow must be eliminated.

Not bad to do weekly 20-25 percentage changes.

The light must be such that it provides good growth for the plants.

Coarse sand, small pebbles, small gravel or expanded clay will be suitable for soil. Better dark.

The thickness of its layer is 5 cm.


Plants need a lot. They should be planted in the ground (vallisneria, rogolotnik, peristristvik) and placed on the surface of the water (riccia, duckweed, piste, nymph).

Thickets are especially needed for the female to hide from the raging male for the spawning period.

Decor – These are different snags, grottoes and so on. Stop the choice is better for those that are also able to serve as shelters. Unplanned spawning: or breeding macropods

I rarely plant macropods to spawn. They and I regularly breed in common aquariums, and I just pick up the nest with caviar, catch the male and transplant them all into the spawn, water in which I pour all of the same total capacity.

The male usually immediately restores his victim when carrying the air lock, collects caviar that has fallen to the bottom and begins to care for her as if there was no transplant.

I do not feed a male while caring for offspring, I do not leave light for the night – he copes well without him. Yes, I met recommendations in the literature about night-time lighting: they say the male sees caviar better, but in nature, no one puts a flashlight on it, and, besides, according to my observations at night, he still sleeps and does not care for posterity.

About a day later, the larvae hatch from the calf, and in a couple of days they spread. At this moment I set the male aside and bring in the first portion of the domestic ciliate-slipper. Sometimes I use dry food Sera micron as an additive.

At the same time I spend cleaning every day, at the same time replacing approximately 80% of the water with fresh water. I pour the old one into the basin so that it would be more convenient to catch (with a plastic cup or a straw from the compressor) the fry pulled together with water into the hose.

At this stage, to create greater feed density, I usually keep the offspring of the macropods in an aquarium with a capacity of about 5-10 liters. After 3-4 days, I begin to give the fry live artemia, and dry food Sera Mikropan, in a week I introduce a microworm, decapsulated Artemia, into the diet, feeding the young with a grindal worm.

The water change mode remains the same.

At one month of age, the fry reach a length of 5 to 8 mm and begin to eat frozen microplankton and cyclops. At this time, I usually transfer them to a larger aquarium, its size depends on how many macropods I want to grow.

This also determines the need for aeration and filtration. Weak blowing in the first month or two of life is useful, but I never put the filter. I do not sort fry, seniors eat small ones and thus make natural selection.

Once I sorted fry and macropods grew really a lot, about a hundred. But then, with great difficulty, I attached this horde to good hands, and the aquariums under them were occupied unnecessarily long, so I prefer to grow 10-20 fish before the time when adolescents are determined by sex – usually 3-4 months.


Planned spawning: or breeding macropods

When planning a spawning, I usually plant a couple in a separate aquarium of 10-30 liters. The female should be with a fat belly. Before this week I feed producers with live food. I don’t put soil in a spawner, I put plants (usually vallysnia) in pots, I let water into the water column, and pistes floating on the surface.

The temperature is usually room temperature, i.e. 22-23 ° C, pH about 7, hardness is also average.

The water level is usually 10-15 centimeters.

The male almost immediately after landing, builds a foam nest on the surface of the water, often under the leaves of floating plants. After completing the work, he invites the female there, “embraces”, squeezing her abdomen, and then fertilizes the eggs that pour from there. Then he releases the female (during spawning, she noticeably turns pale and can stay still for about a minute) and collects fallen eggs into the nest.

If the caviar is not completely swept, spawning is repeated. At the end, the male drives the female away from the nest, and the macropods of the classical and blue colors, as well as the concolors, can beat the partner to death, and the males of the “super red” colors, albinos and rotryukens are more gallant in this regard, and practically do not injure the weak half .

But nevertheless it is better to sow the female, since she distracts the male from the performance of the parental duty and, moreover, can eat caviar.

After this, caviar care is the same as in unplanned spawning.
