The body colouration extending into ultraviolet wavelengths in three species of Lake Malaŵi rock‐dwelling cichlids, Metriaclima zebra, Metriaclima benetos and Metriaclima barlowi was quantified. All three species were ultraviolet reflective with interspecific differences in reflectivity. In addition, individuals were able to behaviourally mediate their reflectivity.
