Existence of home site fidelity and homing ability was established for Pseudotropheus
aurora. Territorial males stayed up to 1½ years within the same territories.
Females showed long-term fidelity to certain places. Transplantation experiments revealed
that P. aurora males home over distances of up to at least 2500 m but would not cross
deep water. The territorial males of five other sympatric species returned from 1000 m to
their territories. The mechanisms and functions of homing in cichlids are discussed.
