Ecology and Biotope of Nothobranchius fishes
The species of the genus Nothobranchius occur mainly in river drainages of eastern and south-eastern Africa that are subject to seasonal rainfall. The temporary habitats dry out seasonally, depending on local rainfall characteristics, either annually or bi-annually. The fish deposit their eggs into the bottom substrate of the habitat. The eggs survive the dry season resting and developing in the substrate and hatch when the next rainy season arrives.
