Guppy fish (Poecilia reticulata) are a popular freshwater aquarium fish known for their bright and colorful appearance, active behavior, and ease of care. They are native to South America, specifically Trinidad, Venezuela, and northern Brazil.

Guppies are small fish, usually growing to about 1-2 inches in length. They have a slender, elongated body shape and come in a wide range of colors and patterns, including yellow, orange, blue, green, and black. Some guppies have iridescent scales that reflect light and make them shimmer in the aquarium.

Guppies are livebearers, which means that they give birth to live young instead of laying eggs. They are also prolific breeders and can quickly populate a tank if not kept in check. For this reason, it’s a good idea to keep only male guppies or a balanced mix of males and females in a community tank, unless you’re specifically breeding them.

Guppies are omnivorous and will eat a variety of foods, including flake and pellet fish food, live or frozen brine shrimp, bloodworms, and daphnia. They prefer a temperature range of 72-82°F and a pH between 7.0 and 8.0. Guppies are generally peaceful and can coexist with other non-aggressive fish in a community tank, although they may nip at the fins of long-finned fish like bettas.

Overall, guppies are a great choice for beginner aquarists or anyone looking for a colorful and active addition to their aquarium.
