Zebrafish will eat their own eggs. Because zebrafish eggs are very small, they are easily eaten by mistake. Zebrafish don't have the concept of protecting fish eggs, so they will be very weak after laying eggs, and it is easy to eat fish eggs as food. Therefore, the large zebrafish after spawning should be fished out in time to avoid eating fish eggs by mistake. When zebrafish larvae are born, try not to change water because it is easy to be washed away. It is also best not to feed egg yolk water, and it is recommended to feed it with backwater. First, do zebrafish eat their own eggs? The eggs of zebrafish are so small that they can hardly be seen without careful observation. Because small fish will hatch from fish eggs, the newborn zebrafish is also very small. Because of its small size, it is easy to be used as food. Whether it is fish eggs or young, it is possible to be eaten. Moreover, fish eggs are a kind of food with high nutritional value in the eyes of zebra fish. Therefore, it is necessary to prepare for isolation in advance to avoid zebra fish eggs being eaten.
2. Precautions for zebrafish spawning 1. Spread a layer of dense glass balls on the bottom of the pond in advance, so that eggs can fall from the cracks in the glass balls to the bottom of the breeding pond. Glass balls can separate parent fish from fish eggs, prevent parent fish from eating fish eggs, and also plant some aquatic plants. In this way, fish eggs can be attached to it without directly touching the bottom of the fish tank.
After it lays eggs, it needs to be as quiet as possible. Creating a quiet environment for small fish is conducive to accelerating its hatching speed. After zebrafish lay eggs, in order to avoid the small fish being eaten by other fish before birth.
3. After laying eggs, the female fish should be isolated immediately, or all the fish in the fish tank should be fished out and the fish eggs should be left alone in a fish tank. When the fish is bigger, put it back in the original fish tank for culture.
