Paracheirodon axelrodi is a small characin species widely known as the cardinal tetra, admired for the intense contrast between its luminous blue lateral stripe and deep red lower body. Native to the soft, acidic blackwater environments of the upper Orinoco and Rio Negro basins, this species represents one of the most iconic examples of beauty and delicacy in tropical aquarium fish. When keeping Paracheirodon axelrodi in captivity, maintaining stable water quality, gentle filtration, subdued lighting, and a calm shoaling environment is essential for bringing out its natural coloration and supporting long-term health.
