The Swordtail, scientifically known as *Xiphophorus hellerii*, is a vibrant and popular freshwater fish originating from Central America, cherished by aquarists for its striking appearance and lively personality.Males are particularly distinguished by their elongated, sword-like caudal fin extension, which can vary in length and often boasts a contrasting color, giving the fish its common name.Available in a dazzling array of color morphs, including red, green, pineapple, and black, Swordtails typically reach an adult size of 4 to 6 inches, with the female usually being larger and more robust, lacking the 'sword' appendage.They are active, peaceful, and hardy fish, making them an excellent choice for community aquariums.Swordtails thrive in well-planted tanks with plenty of swimming space and appreciate stable water parameters (pH 7.0-8.0, temperature 72-79°F).As omnivores, their diet should consist of high-quality flake food, supplemented with brine shrimp, bloodworms, and vegetable matter.Being livebearers, they are prolific breeders, with females giving birth to fully formed fry, which adds an exciting dimension for hobbyists interested in breeding.Their dynamic movement, beautiful colors, and relatively easy care make the Swordtail a captivating and rewarding addition to almost any appropriately sized home aquarium.
