The eggs of guppies are typically small, semi-transparent yellow or pale yellow spheres, approximately 1 to 2 millimeters in diameter, with a regular and plump shape. Here are their specific characteristics:
Appearance Description
Color and Shape: Fertilized eggs are uniformly semi-transparent yellow or pale yellow, with a regular round or oval shape. Unfertilized eggs may be completely transparent or grayish-white, resembling crystal balls.
Size Characteristics: The diameter of the eggs is about 1 to 2 millimeters, and their surface is covered with a sticky substance that allows them to attach to aquatic plants or the walls of the fish tank.
Reproduction-Related Traits
Ovoviviparous Nature: Guppies are ovoviviparous fish. Their eggs are fertilized and hatch inside the female's body. When born, they may be either individual egg grains or fully formed transparent fry.
Embryonic Development: In the later stages, fertilized eggs become opaque, and black spots (the embryos) can be seen inside them.
