Clown Killifish

By | Last Updated : 3rd August 2020

Clown killifish or clown killi belongs to the family of African rivuline indigenous to different parts of West Africa. George Albert Boulenger described them as Haplochilus annulatus in 1915, though finally, Epiplatys annulatus became its generic name.  In Latin “epi” refers to above, “platys” means on top of, while “annulatus” translates to a ring or lateral pattern, perfectly justifying the fish’s banded appearance.
