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.
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", by 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.
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.
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.
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 "Mycopur" 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.
