Species Introduction
The Cardinal Tetra, scientifically known as Paracheirodon axelrodi, is a captivating freshwater fish native to the Amazon River basin in South America. This species is renowned for its vibrant coloration, featuring a striking blue body complemented by a vivid red stripe that runs along its lateral line. These small fish typically reach a maximum length of about 4 cm (1.5 inches), making them an ideal choice for community aquariums.
