The Pristella Tetra, also known as the X-Ray Tetra, is a fascinating freshwater fish characterized by its nearly transparent body, allowing a glimpse of its internal structure. Native to the rivers of South America, this hardy species features striking yellow, black, and white bands on its dorsal and anal fins, with a red-tinted tail fin. Its peaceful nature and adaptability make it a popular choice for community aquariums, where it adds a unique and dynamic visual element.
