Nothobranchius are from Eastern Africa.
They are annual killifish and do best with an egg dry period (typically of 100
days). Males usually are predominante in hatched offspring, believed to overcome
the impact of predation of the more colorful males in the wild habitat. To prevent
odinium (velvet) in the aquarium most do best with a tablespoon of salt per
five gallons of water. In some species males can be very agressive toward other
males of the same species as well as females. These species do best on
live foods and worms are the food of choice although brine shrimp are readily
taken. Dry food is not usually accepted.
