It's not really "sleep" but they do have to shutdown their brains for a rest. That's when they are not alert and get eaten so they hide them selves in a crack, sand, or weeds.

Thanks! I have had fish for years and had never thought about it before, I think he is "sleeping" right now he just kind of flouting there not moving much besides so small fin movements.

She is correct -- fish do indeed sleep. Parrot fish even go so far as to create a sleeping bag of sorts (a mucous-y layer that helps protect them from predators). every night before bed.
