The Jalo Reef population

Copadichromis trimaculatus "Jalo Reef" is the Jalo Reef population of Copadichromis trimaculatus, a geographic colour form from the Malawi coast of Lake Malawi in the south-central part of the lake. It is the same species as Copadichromis trimaculatus, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Copadichromis trimaculatus, the three-spot utaka or "Malawi torpedo," is an open-water zooplankton feeder endemic to Lake Malawi. It belongs to the utaka — the silvery, free-swimming haplochromines that hang in shoals over the lake's offshore reefs, picking copepods and other plankton from the blue water with a remarkably protrusible mouth. The species takes both of its names from the row of three dark blotches along each flank, a mark it wears for life. Breeding males trade that silvery anonymity for a yellow body and steel-blue head, descend to a rocky ledge at 25 to 30 metres, and defend a spawning station to which ripe females come, mate, and depart to brood their eggs alone.
