But no doubt the Cardinal Tetra is the kind that most coveted of ornamental fish for aquarium hobbyists with an amazing color combinations. In the wild, these fish alive until thousands tail clustered in one group. Therefore, if maintained in the aquarium should be flocking to the minimum number of 12. They will stress if kept only a pair only. Cardinal Tetra Fish do not like strong light, they prefer the shade. Although Cardinal Tetra can tolerate a pH between 5.0 to 7.0 but they will spend the most optimal colors at pH 5.8.
Neon colors displayed by the fish is actually a result of light reflection of Iridescent Particles. This tropical fish uses reflected light obtained to reflect red and blue. At night, the Cardinal Tetra will pale, because the particles are not active. Not so clear what purpose the Cardinal Tetra fish colored neon flashy, but it is suspected that the neon colors that stand out are useful for the fish can follow the movements of his group in solid-colored waters (Blackwater)

Water conditions greatly affect the survival of these tropical fish. Neon tetra otherwise more easily adapt to the conditions of the all-new aquarium. An easy way to get water conditions ideal for the cardinal fish (and other tetra species) is by mixing extracts of 'Blackwater' into the aquarium water.
