Live Cardinal Tetra (Paracheirodon axelrodi)
One of the most stunning nano fish in the hobby, the Cardinal Tetra dazzles with a brilliant electric-blue stripe and a bold red stripe that runs the full length of its body — unlike the Neon Tetra, whose red only covers the lower half. A must-have for any planted aquarium or Amazonian biotope.
