Aquarium fish telescope - from black to gold

Telescope fish, the most prominent feature of which are the eyes. They are very large, bulging and prominent on the sides of her head. It is for the eyes that the telescope got its name. Large, even huge, they nevertheless see poorly and can often be damaged about the objects in the aquarium. One-eye telescopes are a sad but frequent reality. This and other properties impose certain restrictions on the content of the telescope.

Habitat in nature

Aquarium fish telescopes in nature do not occur at all. The fact is that all the goldfish were bred a long time ago from a wild crucian. This is a very common fish that inhabits stagnant and slow-moving reservoirs - rivers, lakes, ponds, canals. It feeds on plants, detritus, insects, fry.

The birthplace of goldfish and black telescopes is China, but around 1500 they came to Japan, in 1600 to Europe, and in 1800 to America. The bulk of the currently known species, including the telescope, was developed in the East and has not changed since then.

It is believed that the telescope, like the goldfish, was first bred in the 17th century in China, and was called the dragon eye or dragon fish. A little later, it was imported to Japan, where it received the name "Demekin" (Caotoulongjing) by which it is still known.

Description

The body of a telescope fish is rounded or egg-shaped, as in a veil tail, and not elongated, as in a goldfish or shubunkin. As a matter of fact, only the eyes differ from the telescope from the valehvosta, otherwise they are very similar. The body is short and wide, also a large head, huge eyes and large fins.

Now telescopes are found in very different shapes and colors - with veil fins, and with short, red, white, and most popular - black telescopes. The black telescope is most often sold in pet stores and markets, but it can change color over time.

Telescopes can grow large enough fish, about 20 cm, but in aquariums, as a rule, less. The life of a telescope is 10-15 years, but there are cases when they live in ponds and more than 20. The sizes vary greatly depending on the type and conditions of detention, but telescopes are not less than 10 cm in length and can be more than 20.

Difficulty in content

Like all goldfish, a telescope can live at very low temperatures, but it cannot be called a suitable fish for beginners. Not because he was particularly picky, but because of his eyes. The fact is that they have poor eyesight, which means that it is harder for them to find food, and it is very easy to hurt their eyes or damage the infection.

But at the same time telescopes are very unpretentious and undemanding to the conditions of detention. They live well in the aquarium and in the pond (in warm areas), if the water is clean and the neighbors do not take away their food. The fact is that they are slow and poorly seen, and more active fish can leave them hungry.

Many contain telescopes or other goldfish in round aquariums, alone and without plants. Yes, they live there and do not even complain, but round aquariums are very poorly suited for keeping fish, impair their vision and retard growth.

Feeding

Feed telescopes is easy, they eat all kinds of live, ice cream and artificial food. The basis of their feeding can be made artificial feed, for example, pellets. And additionally, you can give bloodworms, artemia, daphnia, pipemaker. Telescopes need to take into account poor eyesight, and they need time to find food and eat. However, they often dig in the ground, raising dirt and dregs. So artificial feeds will be optimal, they do not burrow and slowly disintegrate.

Content in an aquarium

The shape and volume of the aquarium which will contain the telescopes are important. This is a big fish that produces a lot of waste and dirt. Accordingly, for the maintenance of telescopes need a fairly spacious aquarium with a powerful filter.

Aquariums of a round shape are absolutely not suitable, but classic rectangular ones are perfect. The larger the surface of the water in your tank, the better. Gas exchange occurs through the surface of the water, and the larger it is, the more stable this process is. As for the volume, it is better to start from 80-100 liters for a pair of fish, and add about 50 liters for each new telescope / goldfish.

Telescopes produce a huge amount of waste, and filtration is absolutely necessary. It is best to use a powerful external filter, only the flow from it must be started up through the flute, since goldfish are not important swimmers.

Mandatory weekly water changes, about 20%. As for the water parameters, they are not very important for telescopes.

Soil is better to use sandy or coarse gravel. Telescopes are constantly digging in the ground, and quite often swallow large particles and die because of this.

You can add decor and plants, but remember that the telescope's eyes are very vulnerable, and eyesight is weak. Make sure all the elements are smooth, they have those sharp or cutting edges.

Water parameters can be very different, but ideally it will be: 5 - 19 ° dGH, ph: 6.0 to 8.0, and the water temperature is low: 20-23С.

Compatible with other fish

Telescopes are quite active fish that love the community of their own kind. But for the general aquarium, they are poorly suited. The fact is that they: do not like high temperatures, are slow and dim, they have delicate fins, which neighbors can tear off and they trash a lot.
Who does the telescope fish with? It is best to keep telescopes alone or with related species with which they get along: veiltails, goldfish, shubunkins. It is impossible not to contain them with: Sumatran barbus, ternitse, denison barb, tetragonopterus. It is best to keep telescopes with related fish - gold, veiltails, oranda.

Gender differences

It is impossible to determine the sex of telescopes before spawning. During spawning, white bumps appear on the head and gill covers of the male, and the female considerably rounded from the calf.

CARASSIUS AURATUS FISH TELESCOPE

Order, family: Carp.

Comfortable water temperature: 18-25 C.

Ph: 5,0- 8,0.

Aggressiveness: not aggressive 10%.

Compatibility: with all the peaceful fish (danios, terntion, catfish speckled, neons, etc.)

Useful tips: There is an opinion (especially for some reason, from the sellers of pet stores) that when buying fish of this type you should be ready for frequent cleaning of the aquarium (almost with a vacuum cleaner))). This opinion is justified by the fact that the "Goldfish" nibbled and left a lot of "kakul". So, THIS IS NOT TRUE !!! He himself repeatedly wound up such fish ... there is no dirt - I spend an easy cleaning of the aquarium about once every two weeks. So, do not be frightened sellers tales !!! Fish look very nice in the aquarium. And for greater purity and control of "kakulyami", bring more catfish into the aquarium (speckled catfish, catfish, acanthophthalmos kyuli), and other orderlies from the aquarium !!!

It is also noted that these fish love to eat vegetation - do not buy expensive plants in the aquarium.

Description:

The telescope is one of the fish included in the so-called "Golden Fish" family. The fish is unusual and very beautiful. Received its name for large bulging eyes, which may have a spherical, cylindrical or conical shape. Fish size up to 12cm.

The body is ovoid, the fins are long, anal and caudal forked.

There are two types of telescopes:

- Scaleless: one-color and pied print;

- scaly (velvet black).

The color of the telescope is variable: red, orange, calico, black.

These fish are not very demanding of conditions. The main thing with its content is proper feeding - the key to success is the balance of the feed. The fish is susceptible to intestinal diseases and gill rot.

For the content you need a spacious aquarium with clean water without impurities. Neighbors should not be active and even more aggressive fish - barbs, cichlids, gourams, etc.

Comfortable parameters of water: temperature 18-25 ° C, aquarium water hardness 6-18 o, pH 5.0-8.0. Reinforced aeration and filtration.

The peculiarity of the fish is that it loves to rummage in the ground. As the soil is better to use coarse sand or pebbles, which are not so easily scattered fish. The aquarium itself should be spacious and species, with large-leaved plants. Therefore, in the aquarium it is better to plant plants with hard leaves and a good root system.

Fish in respect of feed unpretentious. They eat quite a lot and willingly, so remember that it is better to underfeed the fish than to overfeed them. The amount of food given daily should not exceed 3% of the weight of the fish. Adult fish are fed twice a day - early in the morning and in the evening. Feed is given as much as they can eat in ten to twenty minutes, and the remnants of non-eaten food should be removed. Feeding 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 feed 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.

Telescope (aquarium fish): care and maintenance

Telescope - aquarium fish. The most remarkable part of it is the eyes. They are quite large, prominent on the sides, bulging. Sometimes, when they first hear the name of the breed of these fish, people ask again: "What is the name of the aquarium fish? Telescope?" Yes, such an unusual name. His fish got it because of the shape of the eyes. It is surprising that with such a huge organ of view the fish see very poorly. And this leads to some restrictions regarding the content of telescopes.

Habitat

Everyone knows that a telescope is an aquarium fish. But in nature, such creatures do not occur. Once upon a time all goldfish were obtained by breeding from a wild crucian. This is a very famous species that inhabits stagnant ponds or rivers, canals, ponds with a very slow flow. It feeds on fry, insects, detritus, plants.

The homeland of black telescopes and goldfish is China. However, in 1500 they found themselves in Japan, in 1600 in Europe, and in 1800 in America. Most of the currently known varieties were bred once in the East and have not changed since then.

It is believed that the aquarium fish telescope, as well as the goldfish, was bred for the first time in the seventeenth century in China. Named it was a dragon fish, or dragon eye. A little later, they were taken to Japan, where they received a new name "demekin", under which they are known to this day.

Description of fish

Telescope - aquarium fish with unusually large eyes. Her body has an ovate or rounded shape, like a voiletail. Actually, these two types distinguish only the eyes. In all other respects, they are quite similar. Their bodies are wide and short, and their heads are large with huge eyes and large fins.

Currently, telescopes are found in a variety of colors and forms, with veil fin. The most popular aquarium fish is a black telescope. It is most often sold in all pet stores, as well as in the markets, but over time it may well change color.

Telescopes grow big enough. Sometimes up to twenty centimeters. The life span of a fish is from ten to fifteen years. There have been cases when they lived in ponds for more than twenty years. Fish sizes vary greatly depending on their species, as well as habitat conditions. But less than ten centimeters they are not.

Aquarium fish telescopes: care

All goldfish, including telescopes, can live at sufficiently low temperatures. However, for beginners aquarists telescope - not the best kind of content. And the reason for this are the eyes of the fish. Telescopes have very poor eyesight, so it’s harder for them to find food. They are often injured and put an infection in the eyes.

But with all this, telescopes are very undemanding and unpretentious to the living conditions. They feel equally good both in the pond and in the aquarium. A telescope is an aquarium fish, the compatibility of which with other inhabitants must be taken into account. Since they see very poorly and are extremely slow, more active individuals can take food from them and leave them hungry. That is why it should be wisely pick them neighbors.

Many people contain goldfish and telescopes in round aquariums, one at a time and without plants. Of course, they are able to dwell there, but round vessels do not suit them at all, they slow down their growth and impair vision.

Feeding telescopes

As for feeding, in this telescopes are unpretentious. They eat all kinds of live, artificial, frozen food. Artificial food can be made the main course in their menu. And as an additional feeding, you can give artemia, bloodworm, tubule and daphnia. It is necessary to take into account the fact that telescopes have absolutely bad eyesight. And so they need time to find food. They very often dig in the ground, raise turbidity and dirt. Therefore, artificial feed is optimally suited, they do not disappear, but slowly disintegrate.

Telescopes sometimes willingly regale with algae. The following types are suitable for them: lemongrass, anubias, nuggets, cryptocorynes, saggitar, elodiea, valisneria. When choosing plants, it should be remembered that they should be soft.

Conditions of detention

The aquarium fish telescope (the photo is given in the article) is quite large. It is characterized by the appearance of a large amount of dirt and waste. For the content of the fish is important not only a large volume of the aquarium, but also its shape. Prerequisite is a good filter.

Circular aquariums are an absolutely unacceptable option. But the usual rectangular fit perfectly. For fish, a large surface area of ​​water is important, as gas exchange processes take place through it.

If we talk about the volume of the aquarium, then for one pair you need 80-100 liters, and for each of the next fish of the same type add another 50 liters.

Telescopes tend to produce a lot of waste. For this reason, good filtering is essential. The best option is to use a strong external filter. Only the current from it must be passed through the flute, since telescopes are not the best swimmers.

Weekly, water should be replaced without fail (at least 20% of water should be replaced). The water parameters themselves are not very important.

As the soil is best to use coarse gravel or sand. Telescopes always dig in it, besides often swallow large particles, which are why they die.

In the aquarium, you can add plants and decor. But remember the poor vision of telescopes and the vulnerability of their eyes. All elements of the aquarium should be smooth, without sharp edges.

The temperature regime for telescopes is not important, but ideally it can be a temperature of 20-23 degrees.

Compatibility with other inhabitants

Telescope - aquarium fish with an active and active character, who loves to communicate with their own kind. But for the content in the general aquarium, it is not very suitable. Telescopes do not like high temperatures, moreover, they are weak-sighted and slow, and their finchs are very gentle, other individuals can pick them off. In addition, they are a lot of trash.

Who can get along with telescopes

The most correct option is to keep them separate. It is possible to lodge with related species: goldfish, veiltails, shubunkins. But categorically it is impossible to combine them with tetragonopteriuses, Denisoni barbus, terntions, Sumatran barbus.

For a telescope, calm, well-balanced neighbors are good, and they won't hurt the fish.

External sex difference

Until the spawning period, it is generally impossible to distinguish the sex of the fish. But during the breeding season, white bumps form on the gills and head of the males, and the female is rounded off from the calf.

Telescope multiplication

For breeding three year olds are most suitable.They are most likely to get good healthy offspring. If you notice the appearance of distinctive sexual characteristics in fish, which we mentioned earlier, this means that fry may soon appear. This usually happens in spring.

By the process itself should be prepared in advance. Very often parents eat their own caviar. Therefore, a separate container should be prepared. At its bottom you can lay Javanese moss. The temperature should be around 24 degrees.

Two weeks before spawning, the male and female should be seated in different aquariums. The female must be transplanted to where the roe will develop. During one spawning, a telescope produces two thousand eggs. Good bright light and strong aeration become the impetus for the start of the process. Immediately after spawning, the female needs to be deposited.

In order that the caviar does not touch the fungus, add "Mikopur" or quite a bit of blue in the aquarium. However, remember that this is absolutely impossible to do while the adult is in the water, otherwise fertilization will not occur.

Eggs will become larvae on the fifth day after spawning itself. They do not need feeding yet. As long as they have a supply of nutrients. But when they become fry, they should be fed live dust. Fry completely unevenly developed. We'll have small and large instances to sit in different places. This is due to the fact that large individuals simply do not allow babies to eat.

Therefore, to obtain offspring from telescopes is not so easy. If you follow all the tips, you can achieve success. But it is very hard work.

Instead of epilogue

If you decide to start a telescope, then note that there are not only black individuals. When dwelling in warmer water, they acquire a copper hue. But the dark-bronze varieties do not have large eyes. However, with age, they appear black color and a characteristic bulge of the eyes. Telescopes - wonderful beautiful fish that require careful treatment. With its rather large size, they are very vulnerable.

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".

Watch the video, revealing the features of the content of the fish telescope.

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.

Telescope fish - content

The content of these fish is very, very troublesome, because these fish are especially whimsical.

In particular, they are very fastidious about the content of oxygen in the water. An aquarium for such fish is best taken large in size - from forty liters to a couple of fish, and in the aquarium with these fish there should be no stones or decorations with sharp corners

. In general, all spicy foods are strictly forbidden because these fish can easily get hurt. The temperature should vary from twelve to thirty degrees from hardness to 20, pH from six and a half to eight.

Telescopes are peaceful fish, so they can very easily be kept next to other peaceful fish. But be careful, because any, even insignificant aggressive fish can very easily injure the eyes of telescopes.

GOLD FISH CARE CONTENTS BREEDING COMPATIBILITY DESCRIPTION.

The best option for keeping telescopes is at a distance from all other fish and in a spacious aquarium in which water is very rich in oxygen. It will also be good to contain telescopes along with the tail fish - goldfish.

In an aquarium in which you will contain telescopes, there should be excellent air blowing and excellent water filtration. Also, it would be useful to triple the aeration of water.

Telescopes are not very good friends with plants that are not well rooted, because telescopes simply pull them out. Plants with delicate leaves, they are biting.

Breeding and spawning

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.

Compatibility of telescopes with other fish Now about compatibility with other aquarium fish. All golds are rather slow and contain them better with fish.

the same temperament, and ideally with their own kind. They are definitely not suitable for neighbors, so to speak, fast-moving fish (such as shark balls), which can easily cause gold injuries.

There is also no talk about suckling fish, such as gerinokhailus or antsistrusov with pterigoplichtami, as they like to travel around the aquarium, clinging to slow-moving fish.

These journeys do not pass without a trace for the "cab driver", traces remain on the body of the fish, and far from being harmless. On the ground, the scales often peel off the scales, or even bloody wounds remain.

Telescopes, like all goldfish, become sexually mature in the second year of life and can reproduce from now on. In the aquarium under optimal conditions of existence of the fish, telescopes live up to 15-17 years.

External description

A goldfish telescope has a swollen round or ovoid body, reaching up to 12 cm in size, and more than half the body length in height. The tail fin is forked and hanging down, the dorsal is vertical, and the remaining fins are long and veil.

Head large, mouth like an accordion pointing down. The eyes are symmetrical, directed slightly forward, each eye is perpendicular to the surface of the head. The special telescopic shape of the eyes is formed by 3-7 months, depending on the temperature in the aquarium.

Types of telescopes

Telescopes are divided into many different types according to certain characteristics:

  • scales form;
  • coloring;
  • shape and size of fins.

Fish are also divided into species according to the structure of the tail fin:

  • skirt
  • tape

Type of telescope fish in color, which may be affected by the care and conditions in the aquarium, the quality of water or soil:

  • the black one is the most common, has a small caudal and long lateral fins, scales are evenly spaced;
  • magpie is white, and fins are black;
  • panda - body pattern represents the alternation of black and white shades;
  • Chinese red - white fishes with large bright red spots;
  • calico - have a motley color, a mixture of black, red, white and blue colors;
  • orange - with a metallic sheen, have a black tail and fins.

    Telescope fish

Differences in eye shape:

  • spherical;
  • cylindrical;
  • dish-shaped;
  • cone-shaped;
  • spherical

The black velvet telescope was developed by the famous Russian aquarist Kozlov at the end of the 19th century.

This aquarium version of the telescope was highly valued due to its unusual color and luxurious skirt tail. This telescope belongs to the scaly type, the color of the abdomen is weakened, gives a grayish-blue or golden hue.

The black telescope is considered to be the most perfect pedigree among the other telescopes.

Aquarium fish telescope - the sister of a goldfish

Fish telescope is a type of goldfish. Another name for them is water dragons. A distinctive feature of these fish is their eyes, which are quite large in size, located on the sides. Due to its size and location, the eyes appear bulging. It is because of them that this fish received such an unusual name. Despite the large size of the eyes, the vision of such fish is very poor, and the eyes themselves are often damaged by surrounding objects. Here is a photo of a fish on which it is clearly visible.

The history of the fish

In nature, a fish telescope is not found. Because it belongs to goldfish, and they were bred from a wild crucian. The crucian lives in a lake, a pond, a river, it lives in many bodies of water, and therefore is considered quite common. The basis of its diet are fry, insects, plants.

Initially, goldfish appeared in China, then in Japan, Europe, and only then in America. Based on this, one can guess that China is the birthplace of the telescope.

In Russia, these fish appeared in 1872. Today they are very common.

What does this fish look like?

Although the telescope belongs to goldfish, his body is not at all elongated, but rounded or ovoid. This fish is very similar to the veiltail. Only the latter has no such eyes. Telescopes are owners of a large head, on both sides of which there are large eyes, besides this, the fish has rather large fins.

Today you can meet a telescope of different colors and shapes. Their fins can be long or short. Colors are also quite diverse. The most popular is considered a black telescope. Such fish can be purchased in the store or on the market. However, sometimes they change color, this should be known to the buyer or owner of this fish.

These fish live for about 10 years. If they live in freedom, they can live to 20. Their size varies, and depends on living conditions, as well as on the species. The average size of 10-15 centimeters, sometimes larger, up to 20. But the fish looks like a telescope in the photo.

Content Features

Low temperatures are not terrible for this fish, they can feel very good even in such situations. Despite the fact that these fish are not picky and do not require any special care, novice aquarists should not get them. This is due to their eyes, because they do not see well, they can not notice the food and starve. Another common problem of telescopes is eye inflammation, because after injuring the mucous membrane, they infect the eye.

In the aquarium, these fish live quite well, but they can survive in the pond. After all, the main thing is the purity of the water, the presence of food and friendly neighbors. The aggressive inhabitants of a pond or aquarium can leave sluggish telescopes hungry, which will inevitably lead them to death.

If you intend to keep them in the aquarium, then you should not get a round version. This is because in such aquariums the sight of the fish deteriorates, and in telescopes it is already very bad. In addition, the fish in the round aquarium can stop growing, this should also be remembered.

Nutrition

Feed telescopes can be:

  1. Live view feed.
  2. Ice cream view.
  3. Artificial view.

It is better, of course, if the basis of nutrition is artificial feed. It is represented mainly by granules. And in addition to the pellets, you can feed with bloodworms, daphnia, artemia, etc. The owners of these fish should take into account the vision of their pets, since in order for this fish to eat and find food, it takes much longer than other inhabitants of the aquarium. I would also like to say that the artificial food slowly disintegrates and does not dig into the ground, so it is he who is given the first place.

Life in an aquarium

For the maintenance of this fish is perfect to purchase a spacious aquarium. However, it must be equipped in a certain way:

  1. Telescopes produce a lot of waste, so the aquarium should contain a powerful filter, it is better if it is external and powerful enough. A daily water change of at least 20% is required.
  2. As already mentioned, round aquariums will not work, rectangular will be more convenient and more practical. As for the volume, it will be optimal to 40-50 liters for one fish. From this we can conclude that if the fish are 2, then water will need 80-100 liters.
  3. As for the soil, it should be either smaller or larger. These fish love to rummage in it, sometimes they can swallow it.
  4. Can be placed in the aquarium plants or decor. But do not forget about the problem eyes of these fish.Before you decorate and diversify your aquarium, you need to make sure that the fish will not get hurt.
  5. Water temperature is optimal from 20 to 23 degrees.

The ability of telescope fish to live with other inhabitants of the aquarium

These fish love society. But it is better if this society is like itself. Other species of fish can injure the fins or eyes of telescopes, due to the fact that the latter are slow and practically blind. You can, of course, put to telescopes:

  1. Voilehvost;
  2. Goldfish;
  3. Shubunkin.

But tertseni, Sumatran barb, tetragonopterus as neighbors do not fit the obsalyutno.

Sex differences and reproduction

Until spawning begins, the girl or the boy does not recognize it. Only during spawning in the female the shape of the body changes, because of the calf contained in it, it becomes round. The male differs only in white bumps on the head.

For healthy offspring, individuals of 3 years are most suitable. Reproduction occurs at the end of spring. In order for the parents themselves do not eat caviar, they must be seated in different aquariums. After spawning has occurred, the female needs to be transferred to the main aquarium.

After 5 days, the larvae will appear from the roe, which do not need to be fed. Feed will need to appear later fry. Fry grow in different ways, so the smaller ones should be planted separately, so that they do not starve, since larger relatives will not allow them to eat fully.

Knowing all the information, to grow and maintain telescope fish is not difficult. But you need to take responsibility for these pets only if you can provide them with optimal and, most importantly, safe living conditions.

Aquarium fish telescope

The aquarium fish telescope is one of the varieties of goldfish that was bred using breeding and does not exist in nature. Telescopes are very loved and demanded by aquarists around the world. Very often, they give birth to those who have just started to maintain and breed fish. However, this is not a good solution, since the telescope requires the host’s attention, as well as all animals that are far from natural forms. This article will tell about the features of care for these amazing creatures.

Where did the telescope come from?

Essentially, the big bulging eyes of these carps are nothing more than a deviation from the norm, a peculiar deformity that pleased the man, and he decided to consolidate this decorative feature in subsequent generations.

Telescopes were brought out in the 16th century in China and for a long time they were only popular in Asia. In Europe, these fish first appeared only in 1872, decorating the collection of the French aquarist P. Carbonier. In the same year, this breeder sold several individuals of A.S. Meshchersky, so Demenkin came to Russia. And by the beginning of the 20th century, through the efforts of domestic breeders, many species of different shapes and colors appeared.

What does a telescope look like?

Dragon fish, as they call it telescopes, has the following structural features:

  1. Slightly shortened, swollen body, resembling a ball or an egg, with a round belly.
  2. A large head, on which are strongly convex eyes and a mouth directed slightly downwards, moving apart with an accordion.
  3. The eyes are so prominent that if you look at the head of the telescope from above, it clearly resembles a hammer. In shape, they can be spherical, dish-shaped, spherical, cylindrical and conical. The eyes of the fish most often look slightly forward and in different directions, but there is a variety of astrologers, whose eyes look upwards.
  4. Scales may be medium or absent.
  5. The dorsal, ventral, and lateral fins are wide, the caudal bifurcated, elongated, and strongly hanging down.

Varieties of telescopes

The basis of the classification demenkinov put such features as:

  1. The shape and size of the fins (tape and skirt telescopes).
  2. Scale form (individuals with and without scales).
  3. Color:
  • black is the most common and frequently occurring species, has a small caudal and long lateral fins, the scales are located in straight rows;
  • the panda is colored symmetrically, the black and white sections alternate;
  • magpie has a white body and black fins;
  • Orange;
  • calico;
  • red chinese.
Fish color can vary depending on the lighting, food and even the color of the soil.

The nature and compatibility of telescopes

These dragons belong to schooling fishes, and it is better to settle them in groups of 4-6 individuals. If the aquarium is not specific, then only peaceful, peaceful neighbors should be selected. For the Demenkin, slowness is characteristic, and therefore the more frisky inhabitants of the reservoir will easily leave them without food. Moreover, this can occur even within the same breed.

Short-bodied (telescope, left head, oranda, ranch) and long-bodied (goldfish, comet, shubunkin) individuals cannot be settled together, because the former are more demanding to habitat conditions, and besides, they risk being offended by the second group and remain hungry because of for them.

Ideal neighbors for the Demenkins are fish with similar temperament and habitat conditions.

An absolute prohibition exists on keeping them in the same aquarium with heratsynymi, tsikhlida, arovanami and other aggressive predators that can eat the telescope.

You also can not lodge them with fighting fish, for example, with a Siamese cockerel. The result of this neighborhood can be dangling fins and damaged eyes. The dragons themselves can harm only small fish and fry, which they take for food.

How to equip an aquarium?

When arranging a home, the main efforts are directed at creating conditions under which the telescope could not damage its most valuable asset - the eyes. These fish will long live and feel well, given that:

Aquarium. The recommended amount of water per fish is from 50 liters. For a flock of 4-6 individuals, you will need an aquarium of 200 liters.

Water. Water quality indicators should be within the following ranges: hardness 8-25, acidity 6-8. The optimum temperature is 21-23 ° C, but telescopes can tolerate a larger range of 18-28 ° C, but without sharp drops.

Filtration. In the aquarium, you need to install a powerful filter with a capacity of 3 volumes per hour, as the fish are large and like to eat, and therefore quickly pollute the water. In muddy water, the demokines may die.

Aeration. The lack of oxygen in the water is unacceptable, therefore, aeration and a weekly replacement of a quarter of the volume of water is needed.

Lighting. In addition to natural lighting, it is advisable to install an additional one, namely fluorescent lamps (0.5 W / l). Telescopes love bright light, and they look more effective with it.

Priming. Fish love to dig in the ground. Therefore, it is better to take gravel or pebbles without sharp edges, or coarse sand. So they themselves do not get hurt, and do not lift the murk from the bottom.

Vegetation. Plants are chosen with large leaves and strong roots (nugget, vallisneria, sagittaria, elodey). Better yet, plant them in pots. Gentle telescopes plants will eat. Danger to the eyes of fish can be plants with hard leaves. Grass is planted in the background, and the front is left to swim.

Registration. Choosing decorations for the aquarium, first of all, pay attention to their safety. Various snags and grottoes will not only impede the movement of clumsy telescopes, but also cause injuries. If you want to decorate the aquarium, it is better to do this with large rounded, non-sharp stones.

Telescope power mode

Demenkiny very unpretentious in this regard, and can eat all kinds of food. The diet needs to be diversified: include live (koretra, bloodworm, tubule) and vegetable food. Of non-traditional products can sometimes give bread and fresh chopped salad.

Food is given twice a day. After a maximum of 15 minutes, residues are removed to prevent water poisoning. Weekly arrange fasting day. A hunger strike a week long, these fish tolerate well.

In the organization of feeding telescopes, there is one subtlety: because of their anatomical features, it is difficult for them to take food from the bottom, a special feeder will come to the rescue, which can be purchased at the pet store.

Telescope multiplication

These fish are considered mature at about two years of age. It is difficult to recognize the female and the male. The readiness of the Demenkins for spawning can be determined by the fact that males become active and begin to swim for females near their egg deposit. It happens in March or April. If before the onset of spring, in order to avoid early litter, they should be seated in different reservoirs for 2-3 weeks.

In advance, you need to prepare spawning (enough 20-30 liters). Arrange it using sandy soil and plants with small leaves. Water should have a temperature of 24-26 ° C, a hardness of 10 and an acidity of 6-7.5. From the evening one male and 2-3 females are run there.

Spawning stimulate the temperature of water by 5-10 degrees. It begins early in the morning. The male chases the female, and she spawns all over the aquarium (up to 10 thousand eggs). After spawning is completed, adult telescopes are deposited, as they tend to eat their offspring. Caviar after two days turns into larvae, and after five more - into fry. They feed them special food, live dust, small rotifers. Grown fry recommended to sort.

Diseases of telescopes

The most common ailments that affect these fish are:

  1. Bacterial infections that cause scabies. In this case, the body of the fish covers whitish mucus, and she constantly itches about stones. To fix the situation will only help a complete change of water.
  2. Fungus. In this disease, thin white threads appear on the body of the fish, which, if left untreated, will turn into a bloom like cotton wool and sprout into the internal organs. Sick telescopes almost cease to move and lie on the bottom.
  3. Defeats by parasites and the simplest organisms.
  4. Oxygen starvation. Signs: Fish often rise to the surface of the water to swallow air. Causes: overcrowding, too high water temperature, reduced oxygen in the water due to rotting plants or food debris. Consequences: appetite falls, growth stops, death. How to fix: reduce the temperature, increase the aeration, clean the bottom. If this is not enough, relocate the fish.
  5. Improper feeding can lead to inflammation of the digestive tract or obesity.
  6. Stress that a transplant can cause, bad water or unsuitable neighbors.
  7. Common cold, which is manifested in the death and exfoliation of the skin. Occurs with sharp fluctuations in water temperature.
  8. Invert. In this disease, the fish does not keep balance, tumbles, hangs at the surface of the water or lies at the bottom.

In conclusion, we say that the content of the telescope is not such a simple matter, it will take a lot of attention and time for proper care. However, an unusual form and funny behavior will bring their owner a lot of happy moments.

Big-eyed sissy

The fish telescope is an artificially bred species of goldfish from the carp family. From Japanese "demagin" translates as "water dragon" or "bug-eyed goldfish." The unusual name of these aquarium fish was due to the structure and shape of their bulging eyes, the size of which in some specimens bred in China reaches 5 cm.

External description

A goldfish telescope has a swollen round or ovoid body, reaching up to 12 cm in size, and more than half the body length in height. The tail fin is forked and hanging down, the dorsal is vertical, and the remaining fins are long and veil.

Head large, mouth like an accordion pointing down. The eyes are symmetrical, directed slightly forward, each eye is perpendicular to the surface of the head. The special telescopic shape of the eyes is formed by 3-7 months, depending on the temperature in the aquarium.

Scaleless telescopes are distinguished by their beautiful scarlet color, but not having the brilliant metallic tint that scaled telescopes have.

Types of telescopes

Telescopes are divided into many different types according to certain characteristics:

  • scales form;
  • coloring;
  • shape and size of fins.

Fish are also divided into species according to the structure of the tail fin:

  • skirt
  • tape

Type of telescope fish in color, which may be affected by the care and conditions in the aquarium, the quality of water or soil:

  • the black one is the most common, has a small caudal and long lateral fins, scales are evenly spaced;
  • magpie is white, and fins are black;
  • panda - body pattern represents the alternation of black and white shades;
  • Chinese red - white fishes with large bright red spots;
  • calico - have a motley color, a mixture of black, red, white and blue colors;
  • orange - with a metallic sheen, have a black tail and fins.

Differences in eye shape:

  • spherical;
  • cylindrical;
  • dish-shaped;
  • cone-shaped;
  • spherical

The black velvet telescope was developed by the famous Russian aquarist Kozlov at the end of the 19th century. This aquarium version of the telescope was highly valued due to its unusual color and luxurious skirt tail. This telescope belongs to the scaly type, the color of the abdomen is weakened, gives a grayish-blue or golden hue. The black telescope is considered to be the most perfect pedigree among the other telescopes.

Content in an aquarium

Caring for telescopes in an aquarium requires a lot of space, where there is at least 50 liters of water per fish. Fish love to dig the ground, so the plants should be chosen with powerful leaves and root system: vallisneria, elodeyu, sagittariya and pods. As a substrate for soil suitable pebbles or coarse sand, which the fish can not easily scatter. But do not place decorative objects with sharp edges, about which telescopes can injure their vulnerable eyes or fins.

It is necessary to provide natural light, good filtration and aeration. Telescopes are very pampered and thermophilic creatures, water hardness should be 8-24 °, acidity 6-8, temperature 12-27 ° С. Regular replacement of part of the water will be the key to the health of the fish.

Nutrition

Telescopes are quite unpretentious in food, eat a little variety of food and know how to slurp funny. Live food and plant foods should be included in their diet. But you need to be careful in terms of overfeeding these fish, the daily dose of food consumed should be about 3% of the weight of the fish. Adults can be fed in the mornings and evenings, and the remnants of uneaten food can be removed from the aquarium.

Breeding

The telescope reaches sexual maturity by 1.5-2 years. For breeding telescopes need a separate spawning or a cell inside the aquarium. During the spawning period, the fish show high activity, the males appear bright spots on the gills, and the females begin to recover. The male pursues the female, chasing her around the aquarium, after which she scatters her eggs. In order to avoid eating eggs, the number of which can reach 5-10 thousand, fish are deposited immediately after throwing eggs.

After about 5 days, the eggs mature and become larvae. They do not need to be fed before they turn into fry.

It should be noted that the crossing of different types of goldfish will lead to the birth of barren outbred hybrids, which is fraught with their degeneration.

Compatibility

Telescopes are peace-loving small fishes, but their slowness and poor eyesight make them unprotected against aggressive representatives of the aquarium who can attack and injure telescopes. Especially unacceptable compatibility of telescopes with cichlids and barbs, which can seriously injure their eyes.

But the telescope is quite unpredictable in coexistence with other goldfish. Due to poor vision, telescopes take longer to find food than other nimble fish.

It is best to keep telescopes in a separate container with the same telescopes or peaceful goldfish of other varieties with which it more or less gets along. Good compatibility will be with such neighbors as aquarium catfish, which are orderlies of the aquarium.

There have been cases when the telescope peacefully got along with large characteristic fish like Congo or ternation.

Hazards and diseases

Proper care of these fish implies frequent water changes, as telescopes are particularly susceptible to intestinal and rot gill diseases. Such diseases as scabies, dropsy, changeling, common cold, ringworm can be treated, but excessive use of antibiotics leads to infertility of fish.

There are several features by which the health of telescopes is determined: vertically raised dorsal fin, mobility, shine of scales, brightness of color and appetite. At the first signs of illness, you need to carefully examine them and correctly identify the disease of the fish. Sick fish should be isolated and treated, and the aquarium and the ground should be thoroughly cleaned.

In addition to diseases, there are other dangers for telescopes in the form of a Cyclops, which the fish did not eat. He attacks their fry and eats, for a week can destroy about 2000 pieces. For adult telescopes, leeches and swimmers are dangerous.

The content of such a fish as a telescope at home is within the power of amateurs and beginners, but this will require compliance with mandatory conditions. Faithful and conscientious care of telescopes and proper compatibility in an aquarium will help to preserve their life and beauty for a long time. In a comfortable environment for health telescopes live up to 17 years.

Fish telescope

Aquarium fish telescopes or water whelps are a type of goldfish, care for which is very difficult. And, if you want to buy telescopes, you should know that they will constantly require your attention. Telescopes are scaly, which are distinguished by metallic luster and scratchless, which are divided into one-color and calico. These fish are distinguished from others by the bulge of their eyes, which comes in a wide variety of shapes. It is the eyes of these fish - the most vulnerable place, so the arrangement of the aquarium should be safe for the eyes. No stones with sharp edges, only polished. For the soil is suitable fine river sand, in which telescopes like to rummage.

Maintenance and care of telescopes aquarium fish

Fish are very sensitive to lack of oxygen. They love clean water. Therefore, aeration and continuous filtration of water, its replacement, the most important conditions for their maintenance. Slight turbidity of the water or algae bloom can lead to the death of the fish. Telescopes love heat. They tolerate water temperatures of 12–28 ° C, but better than 26 ° –27 ° C. Acidity of pH 6.5–8. Telescopes are not demanding for water hardness.

To feed the fish telescopes unpretentious. If you feed fish with live food, it must be pre-frozen. Dry food should preferably not be given more than once a week. Telescopes are very fond of plants, this should be taken into account when landscaping an aquarium. Algae with soft leaves will be circled, so it is better to plant plants with hard leaves and strong roots. From plant foods telescopes give duckweed, valisneria, salad.

Fish telescopes voracious, prone to obesity. They are fed no more than 2 times a day, sometimes they do fasting days.

Aquarium fish telescopes - breeding

Aquarium for spawning should be 50 liters and more. One female and two or three two-year-old males are selected, which before spawning are divided into 2 or 3 weeks. Spawning is best done in the spring. Water in spawning should be fresh and soft with a temperature of 3 - 5 ° C higher than in the general aquarium. Better than 24 - 26 ° C. Active males chase females that spawn, scattering it on the algae in the aquarium. At the end of spawning, the fish are removed from the aquarium. The fry appears after 2 - 5 days, is born weak. The best food for him is "live dust" or special food. The fry grows differently, therefore, to avoid cannibalism, it is sorted.

With whom the telescope gets on, the fish are just like water dragons. They are very slow. Because of this, they are offended by smaller fish. Terascopic fishes can snatch fins. And cichlids and fighting even suck their eyes.

Fish telescopes live up to 30 years, but how long they live depends on your care.

Aquarium fish telescopes and their diseases

Goldfish suffer from diseases of freshwater tropical fish. These are various bacterial and fungal diseases, as well as infection by parasites. The cause of the disease can be stress or injury, water pollution in the aquarium or poor-quality food, lack of oxygen.

The fungus is manifested in the form of various growths, white or gray. The appearance of the fungus is a signal to check the quality of the water.

The parasites that infect telescopes can be anchor worms that lay eggs in their peel. Have the appearance of threads. Their habitats are infected. Under the skin, flukes in the form of nodules parasitize. Other parasites, this fish louse, crustacean - karpoed, black spot.

Of the simplest, ichthyophthirius and chylodon are dangerous. Symptom is clouding of the skin, similar to salt, acting as an irritant.

For goldfish, eye disease is characteristic. If you are seeing a thorn, cloud or cloudiness, you need to pay attention to the quality of food or water.

They also sometimes have constipation or swelling of the body. Symptom of disease is an unusual swimming fish. A lack of oxygen causes the telescope to rise to the surface of the water.
