i leave mine on for 8-12 hours, sometimes longer, depending on what time i get home.

I have a cuban, severum, firemouth and convict and my lights are on for 11 hours. Seems to work fine. I don't think the fish care; it's just for our benefit.

I gota get my fish used to the light being on longer.

Fish dont need lighting. Daylight will do. Lights are for plants, and for us to look at the tank.

I keep mine on for about 12 hours a day. Seems to do well for the fish and plants in he aquarium.

In a fish only tank I would set the timer to go on when you get home from work and turn off around the time you go to bed. Whats that about 6hrs? leaving the lights on too long in a fish only tank is asking for alge more so if you use carbon in the filter. Low wattage .5 WPG is more than enough light.

Unless you have a planted tank you want to use as little light as possable or you'll end up with a bunch of alge
