Claim: The Nimbochromis livingstonii dorsal fin may be blue and the males tend to color up and turn a dark blue during breeding.
Evidence: The dorsal fin may also show blue coloration while maintaining an orange to red band and sometimes a white line. Adult males frequently "color up" in response to changing conditions and rapidly change from spotted camouflage to brilliant blues and greens and may even exhibit a pale golden tone. Breeding males turn a dark blue which almost completely obscures their blotched pattern.
