"Discover the mesmerizing Cardinal Tetra - a vibrant and captivating freshwater fish that adds color and charm to your aquarium."

Detailed Description:

The Cardinal Tetra, scientifically known as Paracheirodon axelrodi, is a mesmerizing and vibrant freshwater fish that has become a favorite among aquarium enthusiasts. With its stunning red and blue coloration, the Cardinal Tetra adds a vibrant pop of color and a sense of charm to any aquarium. In this detailed description, we will explore the water conditions, tank setup, feeding habits, and care requirements necessary to ensure the health and well-being of the enchanting Cardinal Tetra.

Water Conditions:

  • Temperature: Maintain a stable water temperature between 74°F and 82°F (23°C and 28°C) to replicate the tropical environment that Cardinal Tetras thrive in.
  • pH Level: Aim for a slightly acidic to neutral pH level, ideally between 5.5 and 7.0, to create an optimal environment for these fish.
  • Water Hardness: The recommended water hardness ranges from 1 to 5 dGH (degrees of general hardness).

Tank Setup:

  • Tank Size: Provide an aquarium with a minimum capacity of 10 gallons to accommodate a small school of Cardinal Tetras comfortably.
  • Aquascape: Create a well-planted tank with live plants, driftwood, and rocks to mimic their natural habitat and provide hiding spots. Dim lighting can help enhance their vibrant colors.
  • Substrate: Use a dark-colored substrate, such as fine gravel or sand, to showcase the vibrant colors of the Cardinal Tetras.

Tank Mates:

  • Peaceful Community Fish: Cardinal Tetras are peaceful schooling fish and thrive when kept in a group of at least six individuals. They can be housed with other peaceful community fish such as tetras, rasboras, peaceful dwarf cichlids, and small catfish.
  • Avoid Fin-nippers: To prevent stress and potential damage to their delicate fins, avoid pairing them with fin-nipping or aggressive species.

Feeding Habit:

  • Omnivorous Diet: Cardinal Tetras are omnivores and will readily accept a variety of foods.
  • High-Quality Flakes or Pellets: Offer high-quality flake or pellet foods formulated for tropical fish as their staple diet.
  • Supplement with Live or Frozen Foods: Provide occasional treats of live or frozen foods such as bloodworms, brine shrimp, or daphnia to enhance their diet and provide essential nutrients.


  • Water Quality: Maintain excellent water quality by performing regular water changes and monitoring ammonia, nitrite, and nitrate levels. Cardinal Tetras are sensitive to poor water conditions, so maintaining pristine water quality is essential.
  • Gentle Filtration: Utilize a gentle filtration system to ensure water circulation without creating strong currents that may stress the fish.
  • Lighting: Provide moderate lighting conditions by using aquarium lights appropriate for a planted tank. Avoid excessive brightness to prevent stress.
  • Regular Observations: Observe the behavior and appearance of the Cardinal Tetras regularly to identify any signs of illness or stress. Address any issues promptly to ensure their well-being.

In conclusion, the Cardinal Tetra is a mesmerizing and vibrant addition to any aquarium, captivating viewers with its stunning red and blue colors. By providing suitable water conditions, creating a well-designed tank setup, offering a balanced diet, and providing attentive care, you can create an ideal environment for these enchanting fish to thrive. Immerse yourself in the beauty of the Cardinal Tetra and enjoy the colorful charm they bring to your aquatic sanctuary.
