In this blog post, we’ll explore the world of the Cardinal Tetra, including its characteristics, natural habitat, suitability for community tanks, native range, dietary preferences, alternative names, and more.
Characteristics and Size
The Cardinal Tetra is celebrated for its eye-catching appearance, featuring:
- A sleek, elongated body with a vibrant iridescent blue stripe running along its upper half.
- A striking red stripe that stretches from its snout to the base of its tail, creating a dazzling contrast.
- A diminutive size, typically reaching lengths of 1.5 to 2 inches (3.8 to 5 centimeters) when fully grown.
These fish are known for their peaceful nature, making them an excellent choice for community aquariums.
Habitat and Native Range
Cardinal Tetras are native to the soft, acidic waters of South America, specifically the blackwater habitats of the Orinoco and Negro River basins in Venezuela and Brazil. In their natural habitat, they inhabit slow-moving, heavily vegetated waters, often found schooling in the wild.
Suitability for Community Tanks
The Cardinal Tetra is an outstanding choice for community aquariums due to its peaceful temperament and compatibility with a wide range of tankmates. Here are some key considerations:
- Tank Size: Provide a tank of at least 10 gallons (38 liters) to accommodate a school of Cardinal Tetras comfortably.
- Compatible Tankmates: They are generally compatible with other peaceful fish species, such as other tetras, rasboras, guppies, and other non-aggressive community fish.
- Schooling Behavior: Cardinal Tetras are social and thrive when kept in groups of at least six individuals. A school of these fish adds to the visual appeal of your aquarium.
Diet and Feeding Habits
Cardinal Tetras are primarily omnivorous, with a diet that includes:
- Small invertebrates, insects, and larvae in their natural habitat.
- Small amounts of algae, plant matter, and detritus.
- Commercial fish foods, such as high-quality flakes, pellets, and live or frozen brine shrimp, bloodworms, and daphnia.
Offering a varied diet ensures they receive the necessary nutrients. They may also appreciate occasional nibbling on algae-based foods.
Alternative Names
The Cardinal Tetra is also known by its striking appearance, which has earned it the alternative name of “Neon Tetra on Steroids.” However, it should not be confused with the Neon Tetra (Paracheirodon innesi), which is a related but distinct species with a smaller red stripe.
Conclusion
In conclusion, the Cardinal Tetra (Paracheirodon axelrodi) is a dazzling and peaceful addition to a community aquarium, cherished for its vibrant colors and gentle demeanor. By providing a suitable environment, a school of these vibrant tetras can bring a gleaming touch of South America to your own aquatic sanctuary.
