Goldfish - reproduction

Goldfish contained in the aquarium in good conditions, become ready for reproduction at about the age of one year. By this time, the male goldfish acquires small outgrowths that appear on the anterior pectoral fins, and the female has a more bulging abdomen.

Contents and breeding of goldfish

For breeding goldfish in the aquarium should be one female and two or three males. The optimum volume of the aquarium is 2-3 buckets, and the water temperature in it is -22-24 ° С. Sand at the bottom of the aquarium is undesirable, because without it, eggs will be better preserved. But small-leaved plants should be present: an elloderm, a peristaway, fontainaris or others. The aquarium, in which goldfish will spawn, must be illuminated by the sun and an electric lamp for a whole day.

In spring, young male fishes begin to pursue females. The optimal period for spawning goldfish is May-June. Therefore, if you notice that the fish are ready to spawn before the beginning of April, they should be seated in different containers. To stop spawning, you can lower the temperature of aquarium water. Before spawning of goldfish, it is necessary to feed bloodworms, daphnia, earthworm.

On the eve of spawning, males begin to actively drive a female. This activity increases and turns into a fierce pursuit on the day of spawning. Spawning of goldfish lasts about 5-6 hours. The female, swimming between the plants, releases caviar, and the males fertilize it. Sticky eggs adhere to the surface of underwater plants. Initially very small, their diameter is only 1.5 mm. The color of the eggs is at first amber, but then they turn pale, and it becomes quite difficult to consider them.

After the end of spawning fish must be transplanted into another container, as they can eat eggs. From 4-5 days the fry will start to hatch. For their better development, you can reduce the water level in the aquarium. In order to destroy the unfertilized eggs, run snails into the aquarium.
