About the species

Copadichromis jacksoni is a zooplankton-feeding cichlid endemic to Lake Malawi and a member of the lake's "utaka" guild — the shoaling, open-water haplochromines that hover above rocky shores and pick drifting prey from the current. A dark-blue male carrying a clean white blaze across the head and nape makes the species recognizable, but it is one of the lake's quieter utaka: tied to deeper, sheltered, sediment-dusted rocky bays, rarely exported, and only lightly represented in the hobby. It is distributed lake-wide and listed as Least Concern.
