Xiphophorus is a genus of freshwater fish commonly known as swordtails and platies. They are native to North and Central America, particularly in regions like Mexico and Guatemala. These fish are popular in the aquarium trade due to their vibrant colors and unique shapes, especially the males, which often have elongated tails resembling swords. Swordtails and platies are livebearers, meaning they give birth to free-swimming young rather than laying eggs. They thrive in a variety of aquatic environments, including rivers and lakes, and are known for their peaceful nature, making them suitable for community tanks with other non-aggressive fish.
