Capable of surviving in both freshwater and high salinity environments, the Arabian killifish is most often found in estuaries, but also occupies coral reefs and oases 2 4 6.

Help us share the wonders of the natural world. It spawns in areas with an abundance of floating vegetation after the male fish has attracted a female aphamius by fluttering its tail, which displays its vivid colouration 2 3.

Alternatively the adults can simply be removed post- spawning and the fry grown on in the spawning tank.


aphnius The Arabian killifish is found in coastal areas around the Middle East and Northeast Africa, as well as in some freshwater pools and landlocked seas in Egypt, Saudi Arabia and Iran. As with all members of the genus sexual dimorphism is pronounced but in this case the patterning varies according to the origin of the fish.

Spanish toothcarp Aphanius iberus. The incubation period can vary a didpar with the temperature but is usually between days with the fry being large enough to accept Artemia naupliimicroworm etc. Omnivorous although it displays a marked vegetarian tendency compared to most congeners with a large proportion of the natural diet being composed of algae and other plant material. Dorsal fin The unpaired fin found on the back of the body of fish, or the raised structure on the back of most cetaceans.

Arabian killifish biology A highly adaptable and opportunistic species, the Arabian killifish is not aphanuus capable of inhabiting and breeding in both freshwater and saltwater, it will also eat practically anything it can find, including detritusalgae and live aquatic insects 3. A highly adaptable and opportunistic species, the Arabian killifish is not only capable of inhabiting and breeding in both freshwater and saltwater, it will also eat practically anything it can find, including detritusalgae and live aquatic insects 3.


It should also be offered regular meals of small live or frozen fare such as ArtemiaDaphnia or bloodwormthis being particularly important during the months of spring and summer when the fish show a high reproductive effort.

Dominant individuals will show more intense colouration. Found in numerous habitat types although it mostly inhabits shallow coastal waters such as lagoons and first order streams where submerged vegetation or filamentous algae grows thickly. Which species are on the road to recovery? If the aquarium or container does not contain filamentous algae try to introduce a good quality dried product with added Spirulina content to the diet.

It has long been considered doubtful that all populations represent a single species and the fish exhibit variations in colouration and patterning depending on locality; one subspecies already exists and it is likely that others will be named in the future. Unfortunately it is being outcompeted by Gambusia affinis and other introduced species across some parts of its range while habitat degradation and pollution continue to disoar others; some populations have probably been wiped out already and studies suggest the situation is only likely to dispae in the future.
