Cardinal Tetras (Paracheirodon axelrodi) are stunning tropical aquarium fish admired for their vibrant red and blue coloration. To ensure their well-being, maintain them in a tank with stable water parameters: a temperature between 73-82°F (23-28°C) and a pH level of 5.5-7.0. Cardinals thrive in soft, acidic water.
Provide ample swimming space and shelter with live or artificial plants. Their diet should consist of high-quality flake foods, small pellets, and occasional live or frozen foods to replicate their natural diet of insects and tiny invertebrates.
Cardinal Tetras are peaceful and should be kept in schools of at least six individuals for their social well-being. Proper care will reveal their striking colors and schooling behavior, making them a captivating addition to your tropical aquarium.
