FLASHER WRASSE

The species in the genus Paracheilinus are appropriately called flasher wrasses (or simply flashers), and they are very closely related to fairy wrasses of the genus Cirrhilabrus. Dr. John E. McCosker is the ichthyologist credited for originally naming Paracheilinus as the Flasher Wrasse, and this common name is derived from their grandeur "flashing" behavior observed during courting or mating where the male will make quick, exaggerated lateral moves while intensifying his colors and erecting his fins to attract a mate.
