Cardinal TetraParacheirodon axelrodi
The Cardinal Tetra is arguably more colourful than the similar Neon Tetra (Paracheirodon innesi) but must be kept in soft-medium water if it is to show its full colour and lifespan. In hard water the fish is likely to die prematurely from a build-up of salts in the kidneys. Apart from this requirement, once settled the Cardinal Tetra is a relatively hardy and well-suited aquarium fish. In the wild, these fish shoal in groups of hundreds, if kept in the aquarium in small numbers they will become timid, reclusive and more likely to become ill. The Cardinal Tetra is at its best when kept in groups of a dozen or more in aquariums with open areas and spots of dense vegetation. Avoid bright lighting or provide areas of shade.
