Flasher wrasses are favorites among divers and underwater photographers due to their electric blue and red color patterns, which are only displayed as part of a daily mating ritual that normally occurs about an hour before sundown.
At that time, the normally brownish-colored males rise up in the water column and "flash" their spectacular mating coloration while erecting their fins and swimming in short bursts of speed in an attempt to impress nearby female flasher wrasses and encourage them to spawn.
Komodo National Park, encompassing a number of islands and their surrounding waters, is popular with divers, and it's hoped that such discoveries will increase the tourism value of the park.
