Cardinal Tetras (Paracheirodon axelrodi)

These vibrant schoolers are the gold standard for adding a neon pop to a planted tank. Their deep red stripe runs the full length of the body, distinguishing them from their neon cousins and creating a truly electric look under high-quality lighting. They thrive best when kept in groups of at least six, where they feel secure enough to explore the mid-water columns of your aquarium. Give them soft, slightly acidic water and plenty of swimming space to see their best colors and active social behavior.

• Requires stable, clean water parameters with a preference for warmer temperatures.
• Ideally kept in schools of 6 or more to reduce stress and encourage natural movement.
• Peaceful temperament makes them perfect for community tanks with other small species.
• Omnivorous diet; they accept high-quality flakes, micro-pellets, and frozen daphnia.
