Introduction: Introducing the Cardinal Tetra, a true gem of the aquarium world, renowned for its striking colors and peaceful nature. With its vibrant blue and red hues, this small schooling fish will captivate your heart and add a touch of elegance to any freshwater setup. Let’s explore the fascinating features and care essentials of the Cardinal Tetra.

Scientific Name: The Cardinal Tetra is scientifically known as Paracheirodon axelrodi, an eye-catching species with a breathtaking appearance.

Water Quality: Providing pristine water conditions is essential for the well-being of the Cardinal Tetra. Here are the key water parameters:

  • Temperature: Maintain the water temperature between 73°F and 82°F (23°C to 28°C) for a comfortable environment.
  • pH Level: Aim for a pH level between 5.0 and 7.0 for slightly acidic to neutral conditions.
  • GH Level: Keep the general hardness (GH) between 1 to 5 dGH to mimic their natural habitat.
  • KH Level: Maintain the carbonate hardness (KH) between 1 to 2 dKH for pH stability.

Feeding: Cardinal Tetras are primarily carnivores. Offer them a diverse diet of high-quality flakes, pellets, and live/frozen foods like brine shrimp and bloodworms.

Tank Mates: These peaceful tetras coexist harmoniously with other small, non-aggressive fish like other tetras, rasboras, and peaceful barbs.

Substrates and Tank Decorations: Use dark substrates like fine sand to enhance their colors and create a natural setting. Provide plenty of live plants and floating vegetation for hiding and security.

Suitable Plants: Cardinal Tetras appreciate heavily planted aquariums, especially with soft-leaved plants like Amazon Sword and Java Moss.

Sexing: Distinguishing between male and female Cardinal Tetras can be challenging, as there are minimal external differences.

Breeding: Breeding Cardinal Tetras in captivity is complex and requires specific conditions such as soft, acidic water and dim lighting.

Maximum Size and Longevity: Cardinal Tetras typically grow to about 1.5 inches (4 cm) in length and can live up to 3 to 5 years with proper care.

General Information: With their stunning appearance and peaceful nature, Cardinal Tetras are popular choices for community aquariums.

A Fun Fact: Cardinal Tetras are often confused with Neon Tetras due to their similar appearance. However, the red coloration on a Cardinal Tetra spans the entire body, while Neon Tetras only have a red stripe along the lower half of their body.

Dive into a world of vibrant colors and tranquility with the Cardinal Tetra. These captivating schooling fish will create a mesmerizing spectacle in your aquatic haven, leaving you and your guests enchanted by their beauty and grace!
