After the goldfish spawn, the next step of reproduction is hatching. After the goldfish spawn, it is best to fish out the parent fish and place the eggs separately in a container to avoid the parent fish eating the eggs. The specific time of incubation is related to many factors. The most important factor is the water temperature. When the water temperature is suitable, the incubation time will be faster. Specifically, when the water temperature is between 15 and 20 degrees, the incubation time is generally between 3 and 7 days.
However, it should be noted that the higher the water temperature, the better. When the water temperature is higher than 20 degrees, hatching may be faster, but the quality of the hatched fry may not be good. In addition to water temperature, light also affects hatching time. Providing appropriate light exposure may also shorten the incubation time appropriately. In addition, other factors such as water quality, dissolved oxygen and so on need to be controlled. In the whole process of incubation, it is necessary to ensure that all kinds of conditions are suitable.
For newly born small fish, an important aspect is the feeding problem. The newly hatched fish can not be fed. On the second day of their birth and after, they can be fed some egg yolk every day. After hatching for a week, it can be slowly fed with general food, such as seaweed, fish and insects, etc. Then there is the problem of oxygen in the water, you can properly use the oxygen pump to supplement oxygen, and use the filter to clean the fish tank, at this time do not change water frequently. The water temperature also needs to be kept suitable, not too low.
