The Guppy, also known as the Millionfish, is a small and brightly colored freshwater fish that is popular in the aquarium hobby. Guppies are known for their lively personalities, hardiness, and ease of care, making them a popular choice for both beginner and experienced aquarists. They are known for their striking and diverse colors and patterns, with males often having long and colorful tails that they use to attract females. Guppies are also prolific breeders, with females giving birth to live young rather than laying eggs. They are typically peaceful and social, and can be kept in community tanks with other peaceful fish. With proper care and a suitable environment, guppies can live up to 2-3 years.
