Dwarf danios are one of the harder Danio species to breed. They should be placed in a tank with lost of plants. They are egg scatterers so the eggs will be spread throughout the tank and once spawning is complete, the parents should be removed.

The expected life span for Danio nigrofasciatus is 2-3 years.
