The content of goldfish requires special attentionFrom the side of their owner. These water inhabitants are quite capricious in nature, so all the additional elements for the aquarium should be selected very carefully.
Reproduction of goldfish is a special process.
The result of this period depends on your patience and knowledge.
There are many varieties of goldfish. To obtain a good and "high-quality" offspring, one pair of fish of only one species should be planted in a separate capacity during the spawning period. Fry from different parents can inherit completely unpredictable signs, as a result of which it will be problematic to assign small fishes to one or another breed.
Goldfish become capable of reproductionCloser to the year of life. Determine the sexual maturity of fish can be by some external changes. In females, distinctly prominent growths appear on the anterior fins, and the bellies round off. Males change their behavior and try to spend as much time as possible in the society of females. In addition, on the gills, they have light tubercles.
During the transplantation of goldfish for reproductionIn a separate aquarium should pay attention to the potential conditions of their habitat. It is desirable that the situation and water temperature in it practically did not differ from the habitual for a couple of dwellings. Otherwise, long-awaited spawning may be delayed for a long time.
The process of courtship for goldfish takes place inActive form. The male tries in every way to drive the female into the most secluded place. As soon as this happens, he presses the female with his body and waits for the beginning of the laying of the roe. Fertilization occurs immediately after the eggs are released from the body of the female.
Within a few hours, the female may lay eggs several times. The male at such moments is always next to his companion. It is better not to disturb the inhabitants of the aquarium during the spawning rut.
Please note that right afterCompletion of the process of laying caviar of goldfish should be returned to the old aquarium as soon as possible. Otherwise, they can consume their own eggs for food.
Settled caviar is almost impossible at firstNote at the bottom of the aquarium because of the transparent shell. The color begins to change after 1-2 days. Your task is to constantly inspect the aquarium. As soon as you notice the location of the eggs, immediately remove them from the water using a special net.
The eggs should be placed in a solution of blue methylene. This tool can be found in any pet store or pharmacy. This substance will retain the process of vital activity inside the eggs. Otherwise, caviar can catch a fungus, and all the offspring will die. Processing future fry is enough for several hours.
Fry appear from eggs almost in5 days. Grow goldfish quite quickly, but you will almost always have to control the water temperature. The optimal environment for fry is 23-25 degrees.
Feed the fry with special food,Differing in their consistency. Food for young fish usually resembles dust. After 1-2 months the fry can eat food, which is usually offered to adult goldfish.
