Beautiful guppies from a home aquarium

These guppies came to us by accident, as several of the fish began breeding, and over time, their numbers grew significantly beyond our planned size. Currently, the tank contains several young fish with brightly colored tails, constantly swimming among the plants. They are very active, and it's interesting to watch the males occasionally spread their fins. Our tank was quite large, so the fish were doing well, but we've now decided to reduce their population. The fish are healthy, accustomed to stable water temperatures, and are fed regular tropical fish food.
