The species name "Axelrodi" is named after the renowned tropical fish expert Herbert R. Axelrod. Despite its difficulty, getting the spelling right is crucial for identifying and preserving this unique species.
Paracheirodon Axelrodi, commonly known as the cardinal tetra, is a small freshwater fish belonging to the characin family (family Characidae) and the genus Paracheirodon. Native to the blackwater rivers of South America, particularly the Orinoco and Negro River basins in Brazil, Colombia, and Venezuela, this species has gained popularity and is frequently kept in home aquariums.
The cardinal tetra is distinguished by its stunning coloration, which consists of an iridescent blue or greenish-blue body with a vibrant red stripe extending from the head to the tail. Growing up to around 1.5 inches in length, these fish are known for their small size and peaceful nature, making them a popular choice for community aquariums.
In terms of habitat, Paracheirodon Axelrodi prefers water that is soft, acidic, and dimly lit due to the natural conditions of their native environment. They are primarily omnivorous, feeding on small insects, crustaceans, and plant matter. When cared for properly, cardinal tetras can live up to five years.
Due to their delicate nature, it is important for aquarium owners to provide appropriate water parameters, including maintaining stable pH levels, ideal temperature between 72-82°F, and a well-balanced diet. Additionally, it is crucial to keep cardinal tetras in a school of at least six individuals, as they thrive in a social environment.
Overall, Paracheirodon Axelrodi (cardinal tetra) is a beautiful, small-sized freshwater fish that offers an eye-catching display of vibrant colors to freshwater aquariums.
