The cardinal tetra (Paracheirodon axelrodi) is a freshwater fish.

In the aquarium
changeCardinal tetras grow to about 3 cm (1.2 in). They are shoaling fish and like to be kept with other cardinal tetras and they can be kept with other non-aggressive fish. In good conditions the cardinal tetra can live for about five years. The cardinal tetra is a very popular fish but is not as popular as the neon tetra because it is more difficult to breed. They like to live in a temperature of around 23–27°C.
Diet
changeThe cardinal tetra eats live food such as bloodworms or brine shrimp.
