Images used are to show the full potential of the fish when fully mature and are not always representative of juvenile specimens.

How easy are they to care for?
The Cardinal Tetra is arguably one of the most popular specimens available in the aquarium trade with its striking red and blue colouration. Although not a hardy variety, these are of a minimal care, be sure to add to a well established aquarium with a decent number of their own kind and they will happily thrive.

How large can they grow?
5cm

Where in the world are they from?
Tank bred varieties can be found, although they tend to be largely wild caught. They originate from the the middle of the Rio Negro basin (Santa Isabel) to the lower parts of the Rios Vaupes in Brazil. Also found in areas of Guaviare, IÔøΩana, InÔøΩrida, Vichada and Meta.

What is the ideal number to keep together?
Cardinal Tetras are a shoaling species, and are best kept in large numbers. For best results we recommend keeping at least 6 in a shoal - the more the happier they will be.

What water conditions do they require?
Ideally slightly acidic water conditions are provided between 6.5pH - 7pH however they will happily live in conditions ranging up to pH of 7.5 or higher. Temperatures should range between 24-26°C.

What should you feed them?
Cardinals should be fed a variety of flake, frozen, freeze dried and live foods for a varied diet. Being omnivores they will happily accept a wide range of foods.

How compatible are they with other fish?
Cardinal Tetra are peaceful community fish and are generally accepeted by a wide range of tank mates. Please see the compatability chart below or the Advice section for more information.

Can they be bred in captivity?
Cardinal Tetras can be bred in captivity, although it is incredibly difficult as they can be extremely particular about water parameters.
