About the species

Xenotilapia papilio is a small, jewel-like cichlid found only along a short stretch of Lake Tanganyika's southwestern shore in the Democratic Republic of the Congo. Its name means "butterfly," a nod to the delicate yellow-and-black fins it flares during courtship, but its real distinction is ecological: while most of its sand-sifting relatives roam the open lake floor in schools, papilio lives in pairs on sediment-dusted rock. It is also a biparental mouthbrooder, with male and female taking turns carrying the brood, a behavior that has made it a coveted and famously temperamental fish among Tanganyikan specialists.
