Found in Nigeria and Cameroon, the steel-blue killifish is one of many species’ whose eggs can survive in the soil when streams dry up in the dry season. Unlike many killies who only live for about a year, dying after spawning, Fundulopanchax gardneri lives for 2-3 years.


Fundulopanchax gardneri can be kept with other fish that share its parameters, but be aware that it has a disproportionately large mouth and will eat other fish or shrimps small enough to fit. Males can be aggressive towards one another so keeping more females than males can help occupy them in other pursuits.

Housing and Feeding

A well-planted tank is best for this species as the aggression between males means it’s important for there to be hiding places and broken lines of sight.


Kept in the right conditions, the steel-blue killifish will spawn on almost a daily basis, but they will also eat any eggs they find so if you want to rear any young, provide spawning mops or a peat-filled tray and remove the eggs to a separate tank.
