The next full moon is almost here and they are back at it again, tonight one of the females in the tank is rubbing her belley on one of the males in his bed. Interesting note, my tank is in the basement with the curtains drawn, the only window is on the north side and in a spot where the moon can't ever be seen. About two weeks ago on the new moon all of the males quit fanning beds and significantly lightened up in color. Yesterday they darkened up again and started fanning again.
