Goldfish will spawn when they enter the breeding season. However, the number of eggs they lay is not necessarily affected by many factors. For example, if the goldfish is the first spawn, then the number of eggs is relatively small, then the number of eggs may increase. Furthermore is the size of the problem, for smaller goldfish, their spawning will not be too much, larger goldfish spawning will be relatively more. Generally speaking, robust goldfish that have laid many eggs can lay thousands of eggs at a time. Moreover, goldfish can not only spawn once in the breeding season, but also spawn at least 3-4 times. In these spawning, the first and last spawning quantity is relatively small, the second spawning quantity is relatively the most.
Goldfish need to provide them with good water quality to hatch after spawning. The dissolved oxygen in the water is very important, if the dissolved oxygen in the water is too little, or even can not hatch, so to ensure water quality, in order to prevent the reduction of dissolved oxygen. Generally speaking, it is better to incubate them separately in a container, keep the water temperature at 16-18 degrees, and prepare an oxygen pump to supply oxygen. About two days, you can distinguish between fertilized eggs and unfertilized eggs by observation. After about 6-7 days, the small fish can hatch successfully.
