Cardinal Tetra

Cardinal Tetra (Paracheirodon Axelrodi)

The Cardinal Tetra is a stunning and highly sought-after freshwater fish native to the slow-moving, acidic waters of the Amazon Basin. Known for their vibrant coloration and peaceful nature, these fish are ideal for community aquariums, especially those with a focus on South American biotopes.

Appearance:
Cardinal Tetras have a small, slender body that can reach up to 2 inches in length. They display a vivid iridescent blue stripe that runs horizontally along their body, contrasted by a bright red stripe below it that extends from their snout to their tail. Their translucent fins are a subtle, elegant touch to their overall appearance.

Personality:
Cardinal Tetras are peaceful, social fish that enjoy the company of their own kind. They are schooling fish and should be kept in groups of at least 6 to promote their well-being and natural behavior. They are generally non-aggressive and make good tank mates for a variety of similarly-sized, peaceful fish.

Tank Habitat and Care:
Cardinal Tetras thrive in a well-planted, dimly lit aquarium of at least 10 gallons, with plenty of hiding spots and open swimming space. They prefer a soft, sandy or fine gravel substrate and appreciate the addition of driftwood and leaf litter in their environment. Water parameters should be maintained at a pH of 4.0-7.0, a hardness of 1-8 dGH, and a temperature of 73-81°F.

Diet:
Cardinal Tetras are omnivorous and require a balanced diet for optimal health. They should be fed high-quality flake food, small pellets, and a mix of frozen or live foods such as brine shrimp, daphnia, and bloodworms.
