Blue Egger's Killifish (Nothobranchius eggersi)

The Blue Egger's Killifish (Nothobranchius eggersi) is an extremely colorful, peaceful fish whose small size makes it absolutely perfect for the nano or planted aquarium. Native to stagnant swamps and slow-moving waterways in Tanzania, this colorful fish is excellent for aquariums with very low water flow or, under the correct strict maintenance schedule, no water flow at all. It is an "annual killifish," meaning that it lives a rather short lifespan of roughly a year in the wild (although this is sometimes longer in the aquarium). It is easy to breed, however, and an ongoing colony can be established for more long-term keeping.
