Names
Confused with chintz or variegated telescopes .
History of Origin
The scaleless veil-tail telescope was obtained by crossing a Chinese short-tail scaleless telescope and a veil-tail . This breed of fish can simply be called a telescope, because it is a modern combination of the most interesting features of a goldfish - a telescope: elegant and graceful fins, bright multi-color color and amazing grotesque dragon-shaped bulging eyes. The length and shape of the telescope fins are slightly inferior to the veiltail fins, and the color is similar to the shubunkin . The size of the eyes is not inferior to the size of the eyes of the Chinese short-tail telescope.
The homeland of the tiger, as well as the chintz telescopes are the lands of the Prussian kingdom in Germany , where this unusual breed of telescopes was bred in the Berlin area.
At present, as Russian breeds of goldfish - it is extremely rare.
Description
Short ovoid body, all fins elongated, caudal and anal fins of bifurcated veil shape. Dorsal fin "flag-like". A notable feature of all veiled-tail telescopes is their highly swollen and dilated eyes with a cylindrical eyeball. The shape and size of the eyes is not always symmetrical: sometimes only one eye is "telescopic" and the other is normal. The absence of scales is characteristic.
Color
A distinctive feature of the tiger telescope is the verticality of a large number of dark spots along the light body, collected in stripes, which strongly resembles the tiger coloring of fur.
Containment and propagation conditions
Voile telescopes contain:
- Water hardness (gH) up to 20 °;
- The acidity of the water (pH) is 6.5-8.0;
- Temperature (t) 12-28 ° C.
It is dangerous to keep fish with more temperamental fish than telescopes , veil-tails , bubble eyes , etc. Sharp objects can injure the delicate eyes of fish and fins. Soil must be selected in the form of small pebbles .
Feeding
They are unpretentious and omnivorous: they eat both live and plant foods, as well as dry food .
Reproduction
The maturity of telescopes and the possibility of their reproduction occurs one year after hatching fry from eggs. Preparation for spawning is similar to that described for other cyprinids : spawning is arranged in the center of a 100-150 liter aquarium with a spawning grid, one or two sprays and a bunch of small-leaved plants in the center. For one female 2 males. Fertility is from 2 to 10 thousand eggs. The larva leaves after 2 days. On the 5th day, the fry begin to swim. Feeding fry - rotifers .
For breeding:
- Water hardness indices (gH) 8-15 °;
- The acidity of water (pH) is 7.0-8.0;
- Temperature (t) 22-28 ° C.
