Nothobranchius is one of several genera in which you can find Killifish species. All the members of the genus Nothobranchius hail from savannas in East Africa. They are seasonal spawners that will burry their eggs down in the mud where the eggs are ready to hatch at the onset of the next rainy season.

Nothobranchius killifish are very popular among aquarists, even though they have a comparatively short lifespan. They are adapted to a life where they are hatched at the beginning of the rainy season and live their short life before the onset of the next severe drought. The adult fish will die as their home dries out, but the eggs will survive and produce the next generation of Nothobranchius killifish. In the aquarium, the Nothobranchius killifish can survive for over a year but a Nothobranchius killifish that is older than 12 months will usually have lost its vibrant colors and look quite aged.

As long as they are young, the Nothobranchius killifish are however very beautiful fishes with vibration colorations. The most commonly occurring colours in Nothobranchius species are blue and red.

Nothobranchius killifish are not recommended for inexperienced aquarists, since they are a little harder to care for compared to the easiest killifish species. One way of improving the health of your Nothobranchius killifish is to add a little salt to the aquarium water. For each gallon (4 litres) of water you can add 0.5 or 1 tablespoon of salt. The salt will prevent a common aquarium disease known as freshwater velvet. Nothobranchius killifish is known to be highly susceptible to this disease when kept in aquariums.

Unlike many other killifish species, the Nothobranchius species are rarely kept in community aquariums. Species aquariums are much more common for Nothobranchius killifish. If you have 10 litres (2.6 gallon) aquarium you can house up to three Nothobranchius fishes. If you want to house up to ten Nothobranchius killifish, you will need a 30 litre (8 gallons) aquarium. You can house more than male Nothobranchius killifish in your aquarium as long as you create natural borders that make it possible for each male to claim his own territory and stay hidden from the other males. This naturally means that the aquarium also has to be quite large if you want to keep several males together. In a small and poorly decorated aquarium, the males will fight each other violently.

The Nothobranchius killifish will appreciate a well planted aquarium that contains plant species that give the fish a good cover, e.g. Duckweed. Java Fern is also a good choice, especially if you want to breed Nothobranchius killifish.

The recommended diet for Nothobranchius killifish is live food. They are usually happy eaters in the aquarium and will eat pretty much any animal that is small enough to ingest. Cultivating your own Brine shrimp is a comparatively easy and inexpensive way of providing your Nothobranchius killifish with live food. Grindal worms, white worms and several other forms of worms are also suitable as food. You can usually train your Nothobranchius killifish to accept flake food and pellets, but live food is a better solution.
