Exotic Freshwater Live Fish Pack for Aquarium

The Cardinal Tetra (Paracheirodon axelrodi) is a stunning and popular freshwater fish, cherished for its vibrant colors and active schooling behavior. Originating from the upper Orinoco and Negro Rivers in South America, these tetras have captivated aquarium enthusiasts worldwide.

Appearance and Distinction Unlike the more common Neon Tetra (Paracheirodon innesi), the Cardinal Tetra is characterized by its larger size and more vivid coloration. The most striking feature is the horizontal red stripe running along the lower half of the body, from the nose to the base of the tail. This stripe contrasts with the iridescent blue stripe above it, making it unmistakable.

Size and Behavior Cardinal Tetras are relatively small, typically reaching a length of 1.5 to 2 inches (3.8 to 5 centimeters). They are known for their strong schooling instincts, which is crucial for their well-being. Keeping them in groups of six or more helps them feel secure and allows them to exhibit their natural behaviors. In a well-planted aquarium setting, a school of Cardinal Tetras creates an incredible visual display as they swim together.

Tank Requirements To thrive, Cardinal Tetras need a well-planted tank with ample swimming space and hiding spots. Slightly subdued lighting is beneficial, as it mimics their natural habitat. They prefer slightly acidic to neutral water conditions, with a temperature range of 73-81°F (23-27°C) and a pH level around 5.5-7.0.

Dietary Needs Cardinal Tetras are omnivores that accept a variety of foods. High-quality flake or pellet food is suitable, but to enhance their coloration, their diet should be supplemented with small live or frozen foods such as brine shrimp, daphnia, and micro worms.

Tank Mates These peaceful fish generally coexist well with other non-aggressive species. Suitable tankmates include small tetras, rasboras, peaceful barbs, and small catfish. It's advisable to avoid aggressive or fin-nipping fish, as Cardinal Tetras have delicate fins.

By providing the right environment and care, you can enjoy the vibrant beauty and active swimming of a school of Cardinal Tetras in your aquarium.
