Aside from the typical orange and blue variant, there is Nothobranchius rachovii KNP Black[disputed – discuss], which has much darker colors, and was collected from the wild in Kruger National Park, South Africa in 1984,[4] and Nothobranchius rachovii var.

[2] N. rachovii are benthopelagic, feeding on zooplankton and other small organisms living at the bottom of the water (benthos).

[5] Like other benthopelagic fish, N. rachovii prefer to stay at the bottom of the water, right above the benthic zone.

[9] They are able to have offspring by burying their eggs in the river/ lake bed before their habitat dries up- they live in temporary pools dependent on rainfall.

[11] The specific name honours the German aquarist Arthur Rachow (1884–1960), who donated a number of fish specimens to the Museum für Naturkunde.
