Common Name: Cardinal tetra
Scientific Name: Paracheirodon axelrodi
The cardinal tetra has the striking iridescent blue line characteristic of the Paracheirondon species laterally bisecting the fish, with the body below this line being vivid red in color, hence the name 'cardinal tetra'. The cardinal tetra's appearance is similar to that of the closely related neon tetra, with which it is often confused; the neon's red coloration extends only about halfway to the nose, and the neon's blue stripe is a less vibrant blue. The cardinal tetra is very popular aquarium fish but is less widespread than the neon tetra because until recently it was difficult to breed in captivity. The tetras are a schooling fish and look great in groups of 10 or more.
