Chromaphyosemion Killifish

Chromaphysemion is a sub-genus of Aphyosemion Killifish.  They are easy to keep and breed killifish.  Chromaphyosemion killifish should be kept in a well covered aquarium, as they are known jumpers or they are prone to take the "Dramatic Darwin Leap".  There are nine (9) known species and each has variations of color within species, depending upon their population/location.

Chromaphysemion Killifish

General Information

 Chromaphyosemion (Aphyosemion subgenus) are killifish found primarily in Nigeria, from the coastal regions of Central-West Africa, from the border between Togo and Ghana to the West, to the mouth of the Ogooue River, in Gabon, in the South-East.  


Chromaphyosemion thrive in small rivers and streams with thick growths of vegetation in the stream bed and along the banks of the river.  Chromaphyosemion killifish require weekly water changes of 25%-50%, pH of 6.6 - 7.4, dH of 4.0 - 10.0, and plenty of aeration for optimum health and spawning conditions.

Chromaphyosemion are also distinguished from other Aphyosemion and killies generally by their very large and spectacular dorsal and anal fins.


    Chromaphysemions do very well in aquariums of 5 - 10 gallon size.  They do best in well planted aquarium, to simulate their native environment. 


    Chromaphosemion are plant spawners and readily can be bred in the aquarium using the mop spawning method.
