On occasion Divers Den of Live Aquaria has some of the high end fairy and flasher wrasses. However, their prices are not for those looking for cheap but for those looking for prime quality. Marine Center also has high end on occasion but their prices are also not inexpensive. However, you may have difficulty introducing them into a relative small tank with an existing mystery wrasse. I don't recall if the peppermint hogfish will tolerate fairy wrasses.
