The reproductive method of zebrafish is that the mother fish spawns eggs, and then the eggs hatch into small fish. So before it is about to lay eggs, it is best to lay a layer of small stones at the bottom of the tank, or plant some water plants. O that the fish eggs can adhere to the top without directly contacting the bottom of the fish tank. After it lays its eggs, it needs to be as quiet as possible. Create a quiet environment for small fish, which is conducive to speeding up its hatching speed.
The hatching time of fish eggs is not very long, about 2 to 3 days to produce small fish. If you want to shorten its incubation time, you can raise the water temperature appropriately, but not too high. If the temperature is maintained at 25 C, it will hatch in 36 hours.
Zebrafish eggs are very small. If you don't look carefully, you can hardly see it. Because small fish hatch from their eggs, newborn fish are also very small. Because they are too small, they are easy to be regarded as food. Whether it is fish eggs or small fry, there is the possibility of being eaten. Moreover, in the eyes of other fish, fish eggs are a kind of food with high nutritional value. Therefore, in order to prevent the small fish from being eaten by other fish before they are born. After the female fish spawn, they should be isolated immediately. Or take all the fish out of the tank and leave the eggs in a separate tank. After the fish are bigger, they are put back into the original fish tank for feeding.
