Neon Tetra
₹25
Cardinal Tetra | Paracheirodon axelrodi adds a vivid sweep of red and blue to a peaceful community aquarium. Native to the Rio Negro and Rio Orinoco regions of South America, this social tetra is recognised by the bright red stripe running along its body. It grows to around 4–4.5 cm and usually swims in the middle and upper layers of the aquarium.
Cardinal Tetras are omnivores and need small-sized foods suited to them. Keep them in a school in a well-planted aquarium of at least 100 litres; the source recommends 10–12 fish in that volume. They can live with other peaceful, small fish, but larger or aggressive tankmates may cause stress or put them at risk. Breeding is challenging and requires soft water.

The Cardinal Tetra is a popular South American freshwater fish known for its vibrant red stripe and social behaviour. Native to the Rio Negro and Rio Orinoco regions, it grows to around 4–4.5 cm and typically swims in the middle and upper layers of the aquarium. Its vivid red marking helps distinguish it from related neon tetras.
Cardinal Tetras are omnivores and should be fed small-sized foods suited to their size. They thrive in a school in a well-planted aquarium and can share a community tank with other peaceful, small fish. Avoid larger or aggressive tankmates, which may stress or endanger them. Breeding is more challenging than with some other tetras and requires soft water.
