Life History and Reproduction of Nothobranchius fishes
The biological life cycle, reproductive behaviour and egg development of the Nothobranchius species is perfectly adapted to the special conditions of the temporary natural biotopes, in which they occur. The adult fish deposit the eggs into the muddy substrate of the habitat where the eggs survive the dry season while resting and developing in the bottom substrate. Since the survival of the population must be secured during the relatively brief period of a single rainy season, the eggs must be ready to hatch as soon as the rains arrive and the habitat becomes water-filled. The development of the fish is then very rapid in order to reach sexual maturity within the shortest period of time.
