What do zebrafish eggs look like? Do zebrafish eat their own eggs

Zebrafish eggs are spherical, their diameter is generally about 0.6-0.8 mm, and their eggs are light yellow, translucent or white. Fertilized fish eggs will become beige or transparent, while unfertilized fish eggs will be pure white. Breeders need to fish out unfertilized fish eggs to avoid water pollution. Zebrafish are oviparous fish. When they breed, the female fish first produces eggs, and then the male fish inseminate them.

1. What are the eggs laid by zebrafish

The eggs laid by zebrafish are spherical in shape, and the diameter of eggs is generally between 0.6-0.8 mm. The colors are light yellow, white or translucent. If it is fertilized fish eggs, they are generally transparent beige or directly translucent. If it is an unfertilized fish egg, it is usually white. Breeders can tell whether they are fertilized by color, and clean the unfertilized fish eggs from the fish tank, so as to prevent them from polluting the water quality in the fish tank after mildew. Zebrafish is an oviparous fish. When breeding, the female fish lays eggs first, and the male fish is fertilized again.

Second, do zebrafish eat their own eggs

Zebrafish eat their own eggs. They have no habit of protecting their eggs. When they lay eggs, their bodies will be weak, and they will probably eat their eggs as food. When zebrafish lay eggs, the breeder needs to prepare a nylon net for them, so that the eggs will fall directly to the bottom of the tank and will not be eaten by zebrafish. If there is no nylon net, the breeder can also lay a layer of pebbles. The eggs of zebrafish are not sticky, and when they are produced, the eggs will slowly fall to the bottom of the water. After the breeder lays pebbles on the bottom of the water, the fish eggs will fall into the cracks.
