Cardinal Tetra - Paracheirodon Axelrodi

South American Tetras are vibrant and beautiful fish native to the Amazon River basin. With their peaceful nature and shoaling behaviour, they thrive in groups and make a stunning addition to any aquarium. 

Habitat:

Cardinal Tetras are native to the Amazon River basin in South America. They are found in slow-moving rivers, streams, and flooded forest areas.

Tank Setup:

To provide a suitable habitat for Cardinal Tetras, a well-maintained aquarium with a capacity of at least 10 gallons is recommended. The tank should be densely planted with floating plants and have subdued lighting. A dark substrate, such as fine gravel or sand, mimics their natural environment. It is important to maintain stable water conditions with a temperature range of 75-82°F (24-28°C) and a pH level between 5.0 and 7.0.

Diet:

Cardinal Tetras are omnivorous and primarily feed on small insects, worms, and crustaceans in the wild. In captivity, they can be fed a varied diet consisting of high-quality flake or pellet food supplemented with live or frozen foods such as brine shrimp, daphnia, and bloodworms.

Size:

Cardinal Tetras typically reach a size of around 1.5 inches (3.8 cm) in length. They have a relatively slow growth rate and may take several months to reach their full size.

Behavioural Traits:

These tetras are known for their peaceful nature and shoaling behavior. They thrive in groups of at least six individuals and feel more secure when surrounded by their own kind. Cardinal Tetras are active swimmers and enjoy exploring the middle and upper levels of the aquarium.

Water Parameters:

Cardinal Tetras thrive in soft, acidic water with a pH level between 5.0 and 7.0. The temperature should be maintained between 75-82°F (24-28°C). It is important to use a reliable water testing kit to monitor and maintain these parameters.

FACTS:

• Cardinal Tetras are known for their vibrant red and blue coloration, which makes them a popular choice among aquarium enthusiasts.
  
• They are closely related to the Neon Tetra (Paracheirodon innesi) but can be distinguished by the red stripe that extends the full length of their body.
  
• Cardinal Tetras are sensitive to changes in water conditions, so it is important to acclimate them slowly when introducing them to a new aquarium.
  
• These tetras are peaceful and can be kept with other small, non-aggressive fish species that share similar water requirements.
