📋 The Cardinal Tetra (Paracheirodon axelrodi) is among the most iconic freshwater aquarium fish, admired for its brilliant neon blue stripe and vivid red body that extends from head to tail. A close relative of the Neon Tetra, it’s larger and more intensely colored, creating a dazzling effect when kept in groups.
Originating from blackwater tributaries of the Amazon, this species thrives in soft, acidic, well-planted aquariums with subdued lighting and dark substrate. The shimmering red-blue contrast intensifies when maintained in stable, clean water conditions.
Perfect for peaceful community aquariums, Cardinal Tetras are best kept in shoals of 10 or more, providing a mesmerizing schooling display that brings harmony and color to any aquascape.
