This is old-hat stuff for you fish people...but to a lot of people who follow this story, they won't have seen this before!
Here's a quick video showing the leopard wrasse going to bed for the night. Every evening, about 10 minutes after the halide lights go off, he finds a place to sleep and dives in. You don't see him again until about noon the next day.
Sorry for the blue colour of the video...the flourescent lights are on in the evening and I can't do white-balance when I'm shooting video.
