Xiphophorus

Xiphophorus is a genus of freshwater fish commonly known as platies and swordtails, native to Central America. These fish are popular in aquariums due to their vibrant colors and ease of care. They exhibit a range of patterns and sizes, with males often displaying elongated tail extensions called "swords." Xiphophorus species are also important in scientific research, particularly in genetics and cancer studies, as they have been used to understand hereditary traits and tumor development. Their adaptability and diverse features make them both interesting subjects for science and appealing additions to home aquariums.
