Guppies are small, colorful freshwater fish belonging to the family Poeciliidae. They are popular in home aquariums due to their vibrant colors and ease of care. Guppies typically grow to about 1 to 2.5 inches in length and are known for their lively behavior. They thrive in a variety of water conditions and can adapt to different environments. These fish are livebearers, meaning they give birth to free-swimming young rather than laying eggs. Guppies are also known for their rapid reproduction, with females capable of producing several batches of fry each month. Their diet mainly consists of flakes, pellets, and small live foods.
