How to breed goldfish

The maintenance of goldfish requires special attention from their owner. These aquatic inhabitants are distinguished by a rather whimsical character, so all additional elements for an aquarium should be selected very carefully. Reproduction of goldfish is a special process. The result of this period depends on your patience and knowledge.

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

Instruction

1. There are many varieties of goldfish. In order to obtain good and “qualitative” offspring, during the spawning period, fish pairs of only one species should be deposited in a separate tank. Fry from different parents can inherit completely unpredictable traits, with the result that it will be difficult for small fish to be attributed to a particular breed.

2. Golden fishes become capable of breeding closer to the year of life. To determine the sexual maturity of the fish can be on some external changes. In females, distinctly visible growths appear on the front fins, and the tummies are rounded. Males change their behavior and try to spend as much time as possible in the society of females. In addition, on the gills they appear bright tubercles.

3. During the transfer of goldfish for breeding in a separate aquarium should pay attention to the potential conditions of their habitat. It is desirable that the situation and the temperature of the water in it practically did not differ from the usual dwelling for the couple. Otherwise, the long-awaited spawning may linger for a long time.

4. The process of courtship in goldfish takes place in an active form. The male by all means tries to drive the female into the most secluded place. As soon as this happens, he presses the female with his body and waits for the beginning of the laying of the eggs. Fertilization occurs immediately after the release of eggs from the body of the female.

5. Within several hours the female can lay eggs several times. The male at such moments is always near his companion. During the spawning rut of the inhabitants of the aquarium is better not to disturb.

6. Please note that immediately after the process of laying the eggs of goldfish is completed, it is necessary to return them as soon as possible to the old aquarium. Otherwise, they can eat their own eggs for food.

7. Delayed eggs at first is almost impossible to notice at the bottom of the aquarium because of the transparent shell. Color begins to change after 1-2 days. Your task is to constantly inspect the aquarium. As soon as you notice the location of the eggs, immediately remove them from the water with a special net.

8. Caviar should be placed in a solution of blue methylene. This tool can be found in any pet store or pharmacy. This substance will preserve the process of life inside the eggs. Otherwise, the caviar can become infected with a fungus, and all offspring will die. Treat future fry enough for several hours.

9. Fry appear from the eggs after about 5 days. Goldfish grow quite quickly, but you have to control the temperature of the water almost constantly. The optimal environment for fry - 23-25 ​​degrees.

10. Feed the fry need special food, differing in their consistency. Food for young fish usually resembles dust. After 1-2 months, the fry will be able to eat the food, which is usually offered to adult goldfish.

note

The behavior of the male during spawning may resemble an aggressive attack. However, in this way he only tries to provoke and speed up the process of laying eggs by the female.

Helpful advice

Feed the fry need every three hours. If you see that small fish are often near the surface of the water, then do not rush to worry. Thus, they just try to get enough oxygen.

Golden fish breeding and care

Among the most popular inhabitants of aquariums, the interest in which has not faded over the centuries, a special place is occupied by goldfish. Breeding and growing representatives of this group in captivity is a very entertaining and interesting process. Goldfish feel good in a spacious and wide aquarium with good aeration and a layer of soil at the bottom. Water temperature should be from 15 to 24 degrees, hardness from 8 to 200, pH - 5.0-8.0. These are peace-loving creatures that should be kept separate from representatives of aggressive species. The most suitable option for breeding goldfish is a specific aquarium.

If the fish grow in favorable conditions, their maturity comes after a year. In order to control the spawning process, you need to know how to distinguish the sex of goldfish. To do this without a certain experience can be difficult. But if you look closely, you can see that the male has notches on the front rays of the pectoral fins. Females are more complete. During the spawning period, which, as a rule, falls at the beginning of spring, sex differences intensify. The male has small warts on the gill covers, and the females are noticeably rounded due to the presence of caviar. At this time, the behavior of the fish also changes: the males begin to stalk the females, driving them into the overgrowth of plants and in the shallows.

From this point on, goldfish, whose breeding is taken under control, are deposited in a separate (spawning) aquarium. You can also use another container with a capacity of 20 liters or more — a basin, a bowl, etc. The soil is laid on the bottom of the breeding ground and small-leaved plants such as elodea or peristleminous plants are planted. The water level in such a tank should not exceed 20 cm, while it is important to ensure normal aeration and good lighting.

The most beautiful, large and healthy goldfish should be selected, the reproduction of which will give a guaranteed good result. To obtain more fertilized eggs, it is recommended to apply group spawning, choosing 2-3 large males for one female. At a height of 1-2 cm from the bottom, you can tighten the grid, which will protect the eggs from eating. After the female has set aside the last portion of eggs, the producers are removed, and methylene blue or trypaflavin is added to the spawning aquarium to prevent the development of fungi. After a few hours, whitish unfertilized caviar appears, which must be removed. Now the main thing is to maintain a stable water temperature, and in 3-4 days the first larvae will appear, which in a couple of days will gradually turn into fry and begin to swim.

At this stage, attention should be paid to the question of how to feed goldfish. Fry are very voracious and require a good feed base. At first, they can be given ciliates, rotifers and microalgae. Feeding the fry food every three hours, you need to ensure that it is constantly in the water. As the fish matures, small daphnids and cyclops, nauplii of Artemia are added to their ration, and after the first month a tubule and a small bloodworm. At the same time, defective young animals are rejected and sorted by size. Upon reaching 4-5 months, the fish grow up to 4-6 cm, already having all the specific features by this time.

To obtain a successful result, it should be remembered that the optimal environment for the development of goldfish is clear water, well filtered and saturated with oxygen. An additional stimulus to their spawning will be a rise in water temperature up to 25 C. If the early spawning needs to be delayed, it is enough to cool the water in the aquarium a couple of degrees. Under favorable conditions, healthy goldfish will grow in the reservoir, reproduction of which will bring good results.

How to determine the sex of the Goldfish - male or female


HOW TO DETERMINE THE FLOOR OF THE GOLDEN FISH: THE MALE BABY AND THE CABLE!

Everyone wants to know the sex of their goldfish, unless of course the goldfish are not intended solely for decorative purposes. Real goldfish fans usually want to get offspring from them, and here the definition of sex is of particular importance. There are several ways to determine the sex of goldfish.

During the spawning period, males of goldfish are easier to identify than females. Males develop tubercles or white bumps along pectoral fins and gill covers. In addition, males form dented teeth, the so-called "saw", on the male front fins. Females become slightly asymmetric, especially in the abdomen. They look bloated.


Photos of the structure of a goldfish

In the photo clearly visible tubercles casting the Golden male from the female.

At the end of the spawning period and after several spawning spawns in some males, the thoracic region becomes rigid. It is rather difficult to determine this state, therefore, those who are not able to do this can be comforted by the realization that not many can distinguish a goldfish female from a male.

Here are some more ways to determine the sex of a goldfish, but even they are useless, if there is no fish for at least a year*, that is, if the fish has not reached puberty.

1. Males have an outgrowth extending through the posterior part of the ventral fin to the anus. In females, this growth is either completely absent or much smaller.

2. In females, the area between the ventral and anal fins is soft, and in males it is hard.

3. Although it is difficult to see, but the anus of females is round and convex, while the anus of males is thinner and concave.

4. The male's abdominal fins are pointed, and the female's fins are round and shorter.

5. The color of the females is brighter and they are more active. This method will undoubtedly help distinguish the female.

6. You can run the female goldfish in the aquarium and watch the reaction of the other goldfish. Males will swim to a new fish, and females will not show interest.

* Do not be surprised if in the pet store when buying goldfish, give your question to the male and the female, you will be told that this is not possible! Sex differences in the family of goldfish appear only with the onset of sexual maturity, i.e. after 1 year.

Comet fish

This beautiful representative of the genus Karasei. If you are just starting to master the secrets and subtleties of the aquarium business, this fish will be the right decision. With all its simplicity, comet fish is very effective and is able to decorate the simplest aquarium.

Comet Goldfish Content

The content of the comet fish is nothing complicated. It is enough to comply with the basic conditions recommended for this type, and carefully monitor the condition of the cattery. All this is relevant for the content of the comet's black fish.

  1. For this type, you should choose a large enough aquarium. First, the fish will grow to 18 cm in length. And secondly, this type often contain small flocks. In addition, the nature of the pet is quite active and agile. The minimum volume of the aquarium 100 liters.
  2. The ideal is the temperature in the range of 20-23 ° C (at the same time they can live at 15 ° C), pH 5-8.00. It is important to remember that all housing conditions directly affect the appearance of the fish, so even unpretentious species should be kept only with the recommended water parameters.
  3. Be sure to install a powerful filter. The fact is that the comet aquarium fish is very gluttonous, so it will quickly pollute the aquarium. Constantly monitor the accumulation of sludge at the bottom.
  4. From plants it is better to give preference to species with large leaves and a very powerful root system.
  5. To maintain the comet's goldfish, it is important to take care of good quality lighting. This species of fish is distinguished by a bright golden color, which will be visible in high-quality lighting.
  6. For feeding fit any live feed. You can also offer dry, combined or vegetable food. Always carefully monitor the amount of rations consumed, do not overfeed.

Comet aquarium fish - breeding

Fish are ready for breeding from the age of two. Around March-April, you will notice the characteristic behavior of males. They constantly pursue females and at the same time keep as close as possible to the egg deposit.

If you increase the temperature in the aquarium a couple of degrees, then it will go faster. For two weeks we divide the male and the female and feed them as nourishingly and diversely as possible, and go on a hunger strike just before the spawning. Spawning should be about 100 liters, water poured there soft settled.

When breeding a cometfish, be sure to lay a protective net for caviar on the bottom. The period of caviar development is four days, and after five days the fry begin to emerge. Feed the fry should be living dust. With decent care, very soon the young will grow up and it will be possible to switch to rotifers or artemia. As a neighbor, goldfish will do; small species are better not to be moved.

Neon fish: content, compatibility, reproduction, species, photo-video review



Neon content, compatibility, reproduction, species, photo-video review Neons are one of the most popular aquarium fish. These small shiny fish have long won the hearts of aquarists and have taken their deserved place among such mini-fish like guppies, swordtails and tetras.
Neon received such recognition due to its unpretentiousness, compactness and of course due to the neon coloring of the body.

Latin name: Paracheirodon

Order, family: carp-shaped, haracin
(on Lat. Characidae).
Comfortable water temperature: 18-24 ° C
(for manufacturers up to 22 ° C)
"Acidity" Ph:
5,5 - 8°.
(for future manufacturers pH up to 6.8 °)
Stiffness dH:5-20° .
(for future manufacturers - dH to 10 °)
Aggressiveness: not aggressive 0%.
The complexity of the content: easy

Neon Compatibility: non-aggressive, peaceful fish (neons, tetras, swordtails, petsyli, ornatus, pulchera, lanterns).
Not compatible: Neon can not be kept with large, aggressive fish: tsikhly, barbs, large catfish, goldfish, Labe, gourami.
How many live: The life of neon depends directly on the temperature of the aquarium water in which they are contained: 18 ° C - 4 years, 22 ° C - 3 years, 27 ° C - 1.5 years. As can be seen with increasing temperature, the biorhythm of life of neons also increases. That is why they, unlike many other aquarium fish, can and should even be kept in “cool” water. Find out how much other fish live IN THIS ARTICLE!
Minimum Neon Aquarium: from 10 liters, in such an aquarium you can put 4 neons. Neonchiki are schooling fish and therefore it is recommended to keep them in larger aquariums. For information on how much neon can be kept in the X aquarium, see HERE (at the bottom of the article there are links to aquariums of all volumes).

Requirements for care and conditions of neon

- neon necessarily need aeration and filtration, weekly water changes up to 1/3 of the volume of aquarium water.
- it is not necessary to cover the aquarium, although the fish are mobile, they do not jump out of the pond.
- lighting should be moderate. The aquarium is equipped with shading areas, which is achieved with the help of thickets of living plants, as well as with the help of floating plants.
- registration of an aquarium, for your taste and color: stones, grottoes, snags, other shelters. In the aquarium must be provided an open space for swimming.
Feeding and dieting neon: In principle, the fish are omnivores and are not whimsical to feed. We are happy to eat dry, live food and substitutes. But, like many aquarium fish, neons love live food: bloodworms, Artemia, choke, Cyclops, Daphnia. Neon food is taken from the surface of the water or in its thickness. Food that has fallen to the bottom may remain intact. Therefore, the fish should be fed in portions, so that the feed does not have time to fall to the bottom.

Feeding any aquarium fish should be correct: balanced, varied. This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses. Article "How and how much to feed aquarium fish" talks in detail about this, it outlines the basic principles of the diet and feeding regime of fish.

In this article, we note the most important thing - feeding fish should not be monotonous; both dry and live food should be included in the diet. In addition, you need to take into account the gastronomic preferences of a particular fish and, depending on this, include in its diet ration either with the highest protein content or vice versa with vegetable ingredients.

Popular and popular feed for fish, of course, are dry food. For example, hourly and everywhere can be found on the aquarium shelves of food company "Tetra" - the leader of the Russian market, in fact, the range of feeds of this company is striking. In the "gastronomic arsenal" of Tetra are included as individual feeds for a certain type of fish: for goldfish, for cichlids, for loricarids, guppies, labyrinths, arovan, discus, etc. Also, Tetra has developed specialized foods, for example, for enhancing color, fortified or for feeding fry. Detailed information on all Tetra feeds, you can find on the official website of the company - here.

It should be noted that when buying any dry food, you should pay attention to the date of its production and shelf life, try not to buy food by weight, and also keep the food in a closed state - this will help avoid the development of pathogenic flora in it.

HISTORY OF NEONS

The homeland and natural habitat of neons are the streams and rivers of South America: Peru, Colombia, Brazil. Rivers - top p. The Amazons, from a certain São Paulo de Olivenza to Iquitos, live in the r. Putumayo and r. Purus do Boca do Tapaua. As you can see, the natural habitat of neon is very distant and mysterious. That is why the chronicle of these fish in the aquarium world is quite young. The starting point of neon as aquarium fish is the year 1935, when Frenchman A. Rabo discovered these neon fish in the waters of the river Putumayo (Eastern Peru).

Discoverer Auguste Rabo He was delighted and surprised by the beauty of the red-blue fish found, which prompted him to bring several individuals to the United States of America and to Old Europe. In a year - 1936 This species of extraordinary fish was studied and described by the American ichthyologist S. Myers. The second homeland of neon is Germany. This is due to the fact that it was the Germans who managed to first dissolve neons in artificial conditions. At that time - it was a sensation, since neither in the United States of America, nor in France did the fish breed in artificial conditions. The German breakthrough in the breeding of neons was caused not so much by the merits of man as by the presence in Germany of very soft water, which neon fish like so much. Description: Neon is a small, nimble fish. In aquarium conditions, males reach sizes up to 3 cm, and females slightly larger - up to 3.5 cm in length.
Neon Color: There are different types of neon and the color of each is different. In general, all neons are united by one thing - a neon strip passing along the whole body, which actually gives a reflection inherent only in these fish. Behavioral features: Neons - peaceful, gregarious, nimble fishes. Fish are great in the aquarium in a group with a large number. Their briskness requires from the aquarium - space, which is so necessary for maneuvers. The corridors (speckled catfish) are considered to be friends and helpers of neons, they do not interfere with the neonas to monitor the purity of the aquarium soil.

Breeding and breeding neon

Initially, I want to say that the reproduction of neons is not very complicated. At least, it does not require special difficult conditions or hormonal injections.

Sexual differences: Males of neons are smaller than females, somewhere about half a centimeter, they are much slimmer than "girls", and their neon side strip has a clear, even shape, without convolutions. In turn, the females are larger than the males, they are more complete "puzatee", the neon strip bends in the middle of the calf. Preparing for spawning: sexual maturation of neons occurs in 6-9 months. For successful breeding "neon parents" initially contain in comfortable conditions, which consist in the presence of a wide aquarium house, in a diverse feeding and comfortable water parameters. Before spawning, males and females are kept separately, fed abundantly with live food for half a month. When living separately, the water temperature is lowered to 19 ° C.
It is believed that the best producers are fish aged 10-12 months. IMPORTANT: strictly observe the recommended parameters of aquarium water and conditions of detention! From the very hard water, the eggs are not fertilized by sperm (the shell does not allow), but from the very bright light - the eggs die! Spawning aquarium arrangement: an aquarium of 40 centimeters in length, the bottom should be without soil, a separator grid should be installed at the bottom, the back and side of the aquarium should be darkened, the substrate should be dark. Water parameters in spawning: level 15 cm, temperature 20-22 ° C, hardness dH up to 2 °, KH 0 °, pH 5.5-6.5 °, lighting only natural. Spawning water is recommended to be disinfected with UV or ozone. Neon spawning: Having prepared an aquarium for spawning, males and females are planted in the afternoon towards the evening in the ratio of 1: 1 or 3 males per 1 female. Usually, fish spawn at dawn the next morning. However, this process may take 3 days. During the spawning period, neons do not feed anything.
Females toss non-sticky eggs at a time from 50 to 200 eggs.
Immediately after spawning my parents, I set them aside, and the spawning dish is darkened (remember the light is destructive for caviar !!!). It is necessary to set aside producers, as they eat fry.
Within four hours after spawning, it is necessary to monitor the roe and, when the eggs appear white, immediately remove them.
The incubation period for neon caviar is approximately 22 hours.

Neon Fry Care

Juveniles of neons begin to swim already on the 4-5 day, until this point the larvae almost without moving and hang in a spawning aquarium.

Malki require mandatory aeration, water temperature 20-22 ° C and daily replacement of 1/10 of the volume of water, the water in the aquarium should be at a level of up to 10 centimeters.
From the moment the fry begin to swim (4-5 days), they must often be fed in portions. As a starter feed, you need to use special feed for young fish. Such food is sold in many pet stores, for example, TETRA MIN Baby and TETRA MIN Junior or SERA MICROGRAN. You can also feed: grinded boiled egg yolk, rotifers and infusoria.

Growing neon fry, should be carefully treated with lighting spawning aquarium. The lighting is gradually increased, 100% - ordinary lighting can be done only after the young become “on their feet”, and this happens by the 1st month of life. Otherwise, the fry will simply lose orientation.

What ill neons

Fish can get virtually all kinds of contagious and non-infectious diseases. Neons, being small and fragile fish, do not tolerate stress (for example, if they are driven by "bad neighbors"), as well as uncomfortable water parameters and the absence of a schooling lifestyle - which, together and separately, can lead to diseases (for example, ichthyophysis - manke) . Have neons and a disease inherent only to them - plistophorosis or else it is called "neon disease". This infection manifests itself in the form of fading areas on the body of fish - in neons, blue and red stripes fade. The disease is in fact not curable!

USEFUL TIPS:

- neon is better to feed once a day and regularly arrange fasting days (once a week), which in turn will contribute to the health of the fish.
- when making out an aquarium for neons, you should use dark tones of the soil and background.
- a sign of bad health or stress in neons is the blanching of their color, they can fade up to complete graying.
- you should carefully use aquarium preparations containing copper - neons do not tolerate it.

All kinds of neon fish

There are still rare, artificially derived neons: Neon voile

Interesting facts about neons
"Neons: a bloody story" As it was already said before, a certain French national, Auguste Rabo, was the first person to become interested in neons. Well, since he was a dashing businessman and was looking for gold in the tropical forests of the Amazon River, he also caught exotic butterflies and collected orchids, again not for idle curiosity, but for further sale - the reflection of neon fish greedily reflected in gold in his insatiable eyes .
Everyone knows that greed and greed do not lead to good because they are included in the list of deadly sins. Rabo paid for it. And it all happened like this:
Auguste Rabo wandered through the Amazon rainforest and picked up the infection - tropical fever. Benefit pumped his local aborigines - Peruvian Indians. Having labeled Rabo in one of the Indian huts, he first saw the neons that were floating in a makeshift dish. It was then that the business idea of ​​Rabo was ripe, as it was making money on these brilliant little fish.
He organized the transportation of fish to the continent, and the poor neonchik was pushed into wooden crates, missed the gaps with resin, and in addition to the fish during transportation, they did not feed anything. However, the neons were tenacious and safely reached the United States of America.
Most of the surviving neon Rabo sent to Germany, and the rest gave fanatic and connoisseur of tropical fish - William Innesi. Remembering the nature of O. Rabo, it should be said that this was done not out of the goodness of his heart, but for the purpose of a complaint - after all, Innes was the publisher of an aquarium magazine and Rabo hoped to publish an article about his mega discovery, with all the ensuing profit consequences ...
The article was published, moreover, Inessi handed over the fish to ichthyologist D. Mayers, who in 1936 published a scientific work describing a new type of fish and named them in honor of Inessi - Paracheirodon innesi.

Reference:
William Thornton Innes (1874 -1969)
- The state of Philadelphia, USA was born, where he graduated from school. Upon graduation, began to work with his father in publishing. In 1917 he published his first book, "On Goldfish". In 1932 founded his famous magazine "Aquarium", which lasted 35 years. In addition, since 1920, Innes has regularly organized aquarium exhibitions. Also in 1932 published the book "Exotic Aquarium Fish", which was regularly reprinted.
George Myers (1938-1970) - US national: ichthyologist, zoologist and herpetologist, was a professor at Stanford University, from 1942 to 1994. - Professor of the National Museum of Brazil in Rio de Janeiro. So began the neon boom! Employees of the largest aquarium companies have ousted Auguste Raboh, generously and regularly paying him decent sums for the supply of neons. Aquarium dealers hoped to multiply them and thereby return the money spent on Rabo. Yes, it was not there, all the swept up neon caviar died for unknown reasons.
In turn, Rabo, realizing the benefits of his monopoly position, strictly kept the secret of the neon's habitat and secretly left for Amazon for a new batch of fish. This situation lasted for three years until spies of aquarium companies traced Rabo by the Ucayali River, where he was killed. A year later, the delivery of neon fish was arranged without the participation of the deceased.
Neons, what else ?! - Neon is called the initiators of aquarium chemistry. This is due to the fact that for their breeding and obtaining the “desired soft, spawning water” aquarists had to carefully study the hydrochemistry of water, because of which the aquarium case went up to an even higher level.
- Caviar and young neon catastrophically afraid of lighting, from which they inevitably die. Such a malicious joke is played with them by the neon genetic program, which allows the fish to develop only in the twilight, as it happens in the tropical environment of the Amazon River.
- Neons have scales, but under it the skin, which consists of special pigment cells - chromatophore. Actually, they produce from the blood the neon-metallic color of the fish.
- Fish do not emit light, it is only a reflection and refraction of the incident rays of light.
- Not only neons, but also many other inhabitants of the aquarium world can glow with neon. For example, neon goby oceanops (Elacatinus oceanops), the size of which is comparable to neon and is 5 cm.


in the photo is a neon bull - Many lovers of the aquarium world are wondering, why does neonam need such an eye-catching color, is it very dangerous? Until now, there is no scientific explanation for this color of fish. There is only an assumption that they need it to attract a partner in the mating season, as well as to confuse the predator, confusing it when the flock of neons crumbles. Recommended neon literature:

Aquarium fish - telescopes

Fish telescope - a kind of goldfish, in the wild is not found. As is known, goldfish appeared as a result of selection of wild carp. According to reliable data, the telescope fish was bred in the XVII century in China, from which it came to Japan. The most prominent part of the animal's body is large, bulging eyes located on the sides of the head. Due to the unusual shape of the eye, the fish got its name. Unfortunately, these eyes themselves are very vulnerable in the aquarium, they can be damaged by random objects. For this reason, keeping a pet requires maximum care. Caring for fish imposes some restrictions and rules that help protect its health.

Appearance

The telescope of the fish has an oval shape, identical with other representatives of the tail specimen. The symmetry of the body is short and wide. The head is large with bulging eyes, lush fins.

Modern razvodchiki sell small telescope fish of different colors and shapes - with short or long fins, red and white flowers, and, of course, black ones. With age, black telescopes change color scales.


The size of telescopes varies on average from 15 to 20 cm within the aquarium. They live in captivity for a long time, about 15 years. Fish living in artificial ponds, can live up to 20 years.

Content Features

Similar to their relatives, goldfish, telescopes get along in cool water, but they are not recommended to be bred for beginners in aquarism. The point is in the vulnerable eyes, which in addition to the large eyeball, they see almost nothing. Its content is not so simple: you have to look for special food, plants and soil that would not damage the pet's tender body.

On the other hand, caring for telescopes is not difficult if you are extremely careful with them. Like other types of goldfish, they are tolerant of changes in the aquatic environment, can live both in the garden pond and in the glass aquarium. Compatibility is possible with slow, peaceful fish that do not take away their food. It is recommended to settle in spacious aquariums at the rate of 50 liters for 1 fish and more than 150 liters for several individuals. The tank should be safe, without a large number of kryag, sharp objects. They use rounded pebbles of medium size or coarse sand as soil - telescopes like to rummage in the ground. It is important that they do not swallow large parts. Soft plants gnaw, hard-leaved plants - a good choice for their "house".

In the aquarium, you should install a powerful external filter that will remove numerous wastes after pets. The flow is important to pass through the flute, as we know, telescopes float badly. Choose wide containers with a large surface area - through it there is a constant gas exchange.

Do not forget about updating 1/5 of the water once a week. Permissible water parameters: temperature 20-23 degrees Celsius, hardness - 5-19 o, acidity - 6.0-8.0 pH. Not particularly sensitive to the conditions of detention, but quality care for them involves clean water and the absence of sharp surfaces.


What to feed?

Aquarium telescopes are unpretentious in feeding: they feed on live, frozen and artificial food. You can give granules, artemia, bloodworm, tubule, daphnia.Due to poor eyesight, they do not always notice the food without eating it. When feeding fish with artificial food, it is possible to ensure maximum saturation, as they find food for a long time at the bottom of the tank. And such feed slowly disintegrates and does not rot.

Who can live in captivity?

Telescopes can be called friendly fish that behave adequately in relation to their neighbors. Compatibility is proven with related species of fish: voile tail, shubunkin, oranda, goldfish. Such cold-loving fish, not aggressive, do not leave behind a lot of waste.

Compatibility is negative with Sumatran barbs, ternets, burbusi denison, tetragonopterus. These fish can intimidate them, tear off their fins.

Admire the bright telescopes.

Breeding

The reproduction of telescopes is possible in an artificial reservoir in the springtime, when the water is warming. As in the reproduction of goldfish, the female and the male telescope are planted for two weeks in separate aquariums, giving live and artificial food. Before settling in spawning, they are satisfied with the fasting day. Spawning occurs in fresh and softer water with a temperature of 23-25 ​​degrees.


The required spawning volume is 50 liters, a separator grid and several stile-leaved plants are placed there. Usually one female and 2-3 males spawn. The female lays many eggs - more than 2000. Incubation lasts 3-4 days. 5 days after spawning, the larvae will hatch, which will swim in a few days if the water temperature is from 21 to 26 degrees Celsius. The fry are weak and helpless, barely noticeable. Starter feed - live dust. Later you can eat artemia and rotifers. Caring for fry requires constant observation in the spawning aquarium - in order to prevent cannibalism between brothers, large fry should be separated and settled separately from smaller ones.
