Fish often exhibit incredible pigments and dramatic behavior when courting the opposite sex. The most recognized example in marine fish is flasher and fairy wrasses, whose males change into colors so remarkably different than their regular state that they look like entirely different species. For this reason, marine aquarists often keep wrasses in male/female pairs (or harems).
