A distant ancestor of the goldfish – common goldfish that live in marshy lakes and ponds in East Asia.
Body length up to 20 cm rounded Body, with a long veil fins. The color is orange, red, black or spotted. Through many years of breeding hobbyists of the Ancient East were able to deduce many beautiful varieties of goldfish. Among them: telescopes, veiltail, celestial eye, or the astrologer, comets, livingonlove, shubunkin and others. They differ from each other by body shape, fins, color and have long since lost the appearance of a carp.
For keeping and breeding goldfish for a spacious aquarium with well-aerated water. The temperature should not exceed 20 0 C. When the temperature dramatically reduced the content of oxygen in the water, which the goldfish is great. Not worth a planted aquarium with goldfish plants – not fish they feast away. Each adult goldfish relies on 30 l of water, i.e. ten times more than for live-bearing fish. The level of hardness of the water these fish are particularly insensitive.
In the conditions of the room the aquarium breeding goldfish is a simple matter. To determine the sex of goldfish can be white, just semolina, points on guberniyakh males. In females, these dots are absent. For breeding select the most vibrant, young, healthy, agile and active producers, which are separated in advance in 6 – 7 days. Females and males kept in different tanks, all heavily fed with live food. In the spawning area make the hornwort, which is pressed to the bottom of the glass rod. Spawning usually seeded one female and two males.
The water in the spawning area – water, stand for three or four days and well aerated.
During the spawning season to feed manufacturers cannot. Spawning lasts 4 to 5 hours, during which the female spawns up to two thousand eggs. After spawning all producers be removed from the spawning ground to another aquarium with water temperature of 24 0 C and mandatory aeration.
After four or five days from the eggs larvae hatch. Feed them the first two days should not be. The fry need to feed on zooplankton, and then the usual small live food.
