Goldfish

Goldfish – Telescope (moor Carassius auratus) is an ornamental aquarium fish of the Carp family (Cyprinidae). This fish is also called depakinom and a water dragon. The telescope is one of the forms of the goldfish (Carasius auratus), bred through long selection.

The fish – telescopes bulbous rounded body. Its height more than half length of body. The fish have lengthened (up to ¾ of body length) two-bladed tail fin hanging down. The fin on the back stands upright. All other fins – long veil. The name telescope fish was at its largest (about 2 cm), protruding (bulging) eyes. The diameter of the eyes of the instances that took in Shanghai, up to 5 cm Fish – telescopes differ in the length and shape of the fins, color, presence or absence of scales and many others. Telescopes with a tail fin similar to a skirt, usually called a skirt, but if the tail is in the shape of ribbons — strip telescopes. More widespread telescopes, whose velvet-black color of the body, beautiful elongated fins and a forked caudal fin. The height of the body of the fish is equal to ¾ of its length. The black body of the telescope is covered with scales, which is in straight rows.

Telescopes that have symmetrical black and white color are called pandas, but if the torso is painted white, and panicipant black — billed magpie. Distinguished several types of telescopes, depending on the size, shape, and directions of the axes of the eye. Your eyes basically are: disc, spherical, spherical, conical and cylindrical. The eyes should be symmetrical and the same size. The fish, in which the axis of the eye is directed upward, is called the heavenly eye or the stargazers. Such fish is a separate species. Stargazers have a small long forked tail, and lack of dorsal fin.

Peaceful telescopes with a calm nature perfectly coexist with neighbors that have a similar nature. Telescopes kept in aquaria (50 l), with a constant blast of air and thickness of the water layer 30 cm fish are kept in groups of 6 – 8 individuals. If the aquarium is too small (10 liters), it is recommended to only contain one or two adult fish. For soil use a coarse sand or pebbles. Because these fish are constantly digging in it, then this composition will not allow them to scatter much. For necessary large telescopes of the aquarium with a large aquarium plants.

Telescopes instantly ruin the delicate vegetation and leaves of the plants quickly become dirty because of sedimentation for small particles of trash. To avoid this in the planted aquarium plants with well developed root system and rigid leaves. Ideal for such plants as: Sagittaria, Vallisneria and Elodea, which is considered the most hardy. Fish – telescopes trying to contain in an aquarium with non-conflict types of aquarium fish. Telescopes need good natural lighting and excellent filtration. Telescopes are especially sensitive to water parameters. But, like most of corotating all breeds, they are very pampered and thermophilic, and in particular it is characteristic of velvet-black telescopes, but that did not stop them to gain huge popularity among aquarists. Water features for the content of telescopes: hardness 8 – 25°, acid number 6-8. It is advisable to regularly change part of the aquarium water.

Fish-telescopes do not consider choosy with food fish. They are very voracious and can eat a little of everything. In the composition of their diet should be fresh, vegetarian food. Overfeeding them is not worth it. The bulk of their daily feed needs to meet 3% of the total weight of the fish. Telescopes are fed 2 times in the day: early morning and evening. The amount of feed is calculated by about 10-20 minutes of feeding. Leftover feed should be immediately removed from the aquarium. Adult individuals of the telescopes, receiving good nutrition, you can, without harming your health a whole week to stay hungry.

During spawning, male goldfish telescopes will redouble. Because of this, their eye shape appeared and most other goldfish. Such breeds as: shubunkin, the ranch, the pompoms have this eye shape. From the gene that causes the symptom to get rid of almost impossible. Despite the fact that in the first generation offspring does not have telescopic eyes, fishes are widely used for breeding on a commercial basis

All breeds of goldfish, including telescopes able to spawn in a relatively small container (tank) with a volume of 20 – 30 L. this will require placing soil from the sand and planted the plants with small leaves. Spawning planted one a female and two or three two-year-old male. Before arestovany they are kept separately in the order of 2-3 weeks. In the tank is maintained high enough temperature 24 – 26 °C. To stimulate the crossing of water uniformly heated to the moment when its temperature becomes higher by 5-10 °C. When this happens the males begin to dash around the aquarium and chasing females that drop at this time, the eggs. Thus, the eggs scattered throughout the tank, settling mostly on plants. Then the male fertilizes it. The telescope female produces about 10,000 eggs. Once this process comes to an end, producers seeded from spawning.

As an initial food for the fry it is best to apply the “living dust”. In addition they can be fed a special feed made for feeding fry, a huge number currently available for sale. For example, “Sera Mikron”.
