When I started my aquarium, the book I read recommended eight hours of artificial light a day. I put mine on a timer and actually only run it for six hours as the algae was terrible. Bear in mind, mine is a ten gallon fresh water tank, a salt water or living tank may be different.
NO, fish are used to night & day, just like you! Turn it off when you go to bed or put it on a timer. Allow the fish to have some sleep. Light produce heat as a result of which temperature changes which the fish don't like when sleeping.
Also, light disturbs the fish in sleep.
What else can I help you with?
What hours should you leave the light on for fish?

Do fighting fish like light?
No fish likes direct light. They hunt for other fish, so your lure should either sparkle or jiggle(to look like a wounded fish). Live bait should be very lively where possible
When should the light over the fish tank be on?
You should be aiming for between 8 and 12 hours. about the same time as the sun is up. this helps with the natural environment of the tank, the plants will grow nicely, there wont be loads of algae everywhere, and your fish will behave more naturally. this can obviously be adjusted to suit when you will be looking at the tank, after all your paying for it :P. I have mine on around 11am-9pm because this is when im most likely to be home! too light can lead to an algae bloom and make your tank go green, if this happens don't leave your tank on for so long. it might also help to keep natural sun light off of the tank. tom :)
