Ecology
Habitat
Zambezi River Benthopelagic Habitat
This taxon is one of a number of benthopelagic species in the Zambezi River system of southern Africa. Benthopelagic river fish are found near the bottom of the water column, feeding on benthos and zooplankton
Nutrient levels in the Zambezi River are relatively low, especially in the upper Zambezi; in that reach, above Victoria Falls, most of the catchment drains Kalahari sands, whose nutrient levels are inherently low due to their aeolian formation; moreover, agricultural fertilizer addition throughout the Zambezi watershed is low, due to the shortage of capital available to farmers of this region.
Nitrate levels (as nitrogen) in the upper Zambezi are typically in the range of .01 to .03 milligrams per liter. Correspondingly electrical conductivity of the upper Zambezi is on the order of 75 micro-S per centimeter, due to the paucity of ion content. From the Luangwa River downstream nitrate levels elevate to .10 to .18 milligrams per liter, and electrical conductivity rises to a range of two to four times the upper Zambezi levels. Not surprisingly, pH, calcium ion concentration, bicarbonate and electrical conductivity are all higher in portions of the catchment where limestone soils predominate compared to granite.
There are a total of 190 known fish species present in the Zambezi River, including eel and shark taxa. The largest native benthopelagic fish in the Zambezi are the 170 cm North African catfish (Clarias gariepinus), the 146 cm common carp (Cyprinus carpio carpio), the 150 cm Indo-Pacific tarpon (Megalops cyprinoides) and the introduced 120 cm rainbow trout (Oncorhynchus mykiss).

Nothobranchius rachovii
Contents |
Introduction
Nothobranchius rachovii (Ahl, 1926) is a species of freshwater annual killifish from Mozambique and South Africa.[1] It can grow up to 6 cm (2.4").[2] It is popular among killifish enthusiasts, who raise them from eggs in aquaria.
Variants
Aside from the typical orange and blue variant, there is Nothobranchius rachovii KNP Black, which has much darker colors, and was collected from the wild in Kruger National Park, South Africa in 1984,[3] and Nothobranchius rachovii var. Red, which has a red head with turquoise highlights.[4] The females of all varieties are more neutrally colored.
In the Aquarium
Nothobranchius rachovii can be housed in a 40–60 litre (10–15 gallons) aquarium. Males are aggressive toward other males of the same species.[5] They can be kept in a community tank of similar-sized peaceful freshwater tropical fish.
