1. Do zebrafish lay eggs in isolation? When zebrafish lay eggs, they need to isolate their parents, because their eggs are relatively small, and most zebrafish lay eggs from early morning to around 10 o'clock, so breeders can't stay by all the time. In addition, zebrafish have no habit of protecting fish eggs, and often eat them as food. In order to ensure the safety of fish eggs, breeders also need to isolate them.
In addition, zebrafish will have the problems of irritability and decreased activity before laying eggs. If conditions permit, it is best to isolate them after estrus.
2. What to do after zebrafish spawning1. Parent fish: After zebrafish spawning, the breeder needs to transfer the parent fish to a separate container and feed them some high-nutrition food, so as to speed up their recovery. After they return to their original state, the breeder can put them in the original tank for breeding.
2. Fish eggs: The breeder needs to keep the water temperature at 26 ℃ and install heating rods to avoid temperature difference. Wait for 2-3 days, and the eggs can hatch small fish. Small fish have just hatched successfully, so breeders don't need to feed them immediately. Because they carry vitellotin, these nutrients are enough for them to absorb for a few days. When they are born for about 3 days, the breeder can try to feed some good-year shrimp eggs, cooked egg yolks and other foods.
