It is hard to say for sure, but fish enter a state of rest - but do not completey switch off the way humans do.
The fish needs to be on alert constantly to avoid being eaten by predators.
At night if I wave my hand in front of the tank (with a dim light in the room) the resting fish scatter, so one would assume they can "see".
It is also important to note fish dont have eyelids, so they can't "close" their eyes and shut out the picture. Similar to snakes.
