The color of the male guppy is bright and colorful, and the fins are long, and there are round patterns on the tail fin, like peacock feathers, which are very beautiful. Female guppies are relatively single in color, generally only silver-gray or blue-gray. The fins of the female fish are also relatively short, and the color and pattern of the tail fin are not obvious. In adulthood, the anal fin of male guppies will develop reproductive feet, while the anal fin of female guppies will not change.
