Aquarium fish telescope

maintenance, care, compatibility

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 begun to engage in the maintenance and breeding of 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.

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.

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.

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.

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.

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.

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.

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.


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.

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.

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 food 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 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.

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.

Fish telescopes are one of the artificially bred varieties of goldfish. They have a rounded body shape, hanging forked tail and veil, long fins relative to the body.

Their original name “telescopes” received thanks to the bulging eyes, having a size of, on average, up to two centimeters. Some specimens, bred in China, have eyes in two, or even three times more.

Fish telescopes may differ from each other in the following ways:

  • in shape and size of fins,
  • by color,
  • in the form of scales.

The following types of telescope fish are distinguished according to the shape of the tail fin:

  • Black telescope
  • Panda,
  • Magpie,
  • Red Chinese telescope,
  • Orange telescope,
  • Calico telescope.

The first type of black velvet telescopes, often encountered and the most common, has a small tail and long side fins. His scales are arranged in even rows.

Pandas have a symmetrical color with alternating white and black shades. Magpie called telescopes with a white body and black fins.

Coloring can change the intensity depending on the conditions of detention, the quality of the soil and water.

Fish telescopes also differ in the shape of the eye:

  • disc,
  • spherical
  • cone-shaped
  • cylindrical.

Telescopic goldfish for a comfortable stay should be kept in aquariums, the volume of which should not be less than fifty liters. Such a volume is needed for one individual, if you contain two telescope fish, then it should be increased to one hundred liters.

As a bottom flooring in the aquarium, it is better to use pebbles or sand with large grains of sand; plants will suit with thick leaves and a hard root system. Despite their calm behavior, such fish actively scatter the soil and subject tender varieties of plants to death. They like calm neighbors, room temperature and any suitable food.

In food unpretentious, but they need to be fed no more than twice a day. The maintenance of telescopes does not require any special conditions, like other ornamental fish, they require regular aeration, filtration and feeding.

The appearance of black telescopes is more pampered, requires low acidity, hardness and frequent changes of water. The daily amount of food consumed should be divided into 2 times and feed in the morning and evening, twice a day.

During the spawning period, the male telescopes are more active. For breeding individuals suitable with an age of 1.5 – 2 years. In such a period, the males are characterized by the appearance on the gills of light cereal placers, the females begin to “gain weight” due to the eggs.

To stimulate spawning, high aeration and temperature of 25-26 degrees Celsius should be maintained. Reproduction of telescopes occurs as follows: after the male matures for spawning, he begins to pursue and catch up the female, which is why she is forced to scatter her eggs throughout the aquarium.

One female is able to lay up to 5-10 thousand eggs at a time. Very often they are eaten by the fish themselves, therefore, adults should be immediately transplanted to another aquarium after mating and throwing eggs.

Especially cannibalism subject to the black telescope and calico goldfish.

Eggs begin to ripen and after about five days turn into larvae. Feed the larvae do not need to until they turn into fry.

Fry grow unevenly, if there is a desire to preserve the weaker, you should regularly select them and transplant to another aquarium.
