Description

Christy's killi is a small, colourful killifish of the family Nothobranchiidae (African killifishes) reaching about 6 cm. The male is beautifully marked, with a blue-green body full of red spots and coloured edges to the fins, while the female stays a plain brown. The species lives in small groups in quiet, shaded forest streams and swamps of the Congo basin in Central Africa. As a hunter just below the surface it eats insects, midge larvae and small zooplankton. It lays its eggs among fine water plants and leaf litter. Because of its handsome colours it is sought after by specialist killifish keepers, who keep and breed it in species tanks.
