Copadichromis borleyi is a species of haplochromine cichlid fish endemic to Lake Malawi. C. borleyi is a relatively small cichlid, males grow to 5–6 in total length, while females are typically slightly smaller. In addition to these minor difference in size, the species displays marked sexual dimorphism with males displaying larger ventral fins marked with egg spots, light-blue edging to the dorsal and ventral fins, along with metallic blue colouration of the head, and yellow to red flanks. In contrast, females are silver-to-brown and display three black spots along their sides. Juveniles are monomorphic and are coloured like the adult females. C. borleyi is widespread in Lake Malawi, occurring along the coasts of Malawi, Mozambique and Tanzania. The species is limited to littoral zones with large rocks and boulders. The water in which species is found is warm 75 – 84 °F, hard and alkaline; typical of the water chemistry of Lake Malawi. The species feeds primarily on zooplankton, by means of specialized, suction feeding action and highly protrudable mouth. C. borleyi is a polygamous, maternally mouthbrooding cichlid. Males frequently claim areas adjacent to, or on top of, large, submerged boulders and spawn on the horizontal upper surface of the boulder. Some geographic variants are known to build sand bowers atop large rocks in which spawning and courting takes place.
