my tank which previously i kept goldfish in, (i gave it a clean out and complete resetup) has always had the light on for 24 hours a day, now i've realised that it shouldn't be on 24 hours i'm not sure what to do, could some one give be some advice on lighting. Will the fish get confused if i suddenly start turning the light off. Please help

Well, although I'm a little new to all this, what I usually do is turn the light on when I wake up, and then its the last light to go off when I go to bed. As far as the fish being confused, I'll let the other guys on the board help you out. I don't think it should, but let the others help too.

the fish will get used to it. they do need their sleep time anyway. all organisms do. even plants. they'll eventually get used to the light turning off suddenly, especially if you turn it off at the same time every night ;)

So as to not shock the fish, a good way of doing this is to turn the lights in the tank off about 1/2 hour before the lights in the room go off at bedtime. Same thing on winter mornings when it is still dark when you wake up. Turn some lights on in the room about 15 minutes before turning the tank lights on. This gives them a chance to gradually get used to the lights on/off, and will be less startling.

As lboy said, they do need some "lights off" time in order to allow them to rest.

I have a computer timer that turns the light on at 7 am every day and turns them off at 8 pm every night. I figure that most of the tropicals that we keep are "wired" to light at the equator 12 hours +/- 1 hour of light and dark.

Just my $0.02 worth.

Twelve hours is too much light unless you are growing a lot of plants Matthew. You may have problems keeping up with the algae! I suggest about 9-10 as sufficient. At the equator there are lots of plants and algae is not a problem anyways.

I have a regular timer that turns on my tank light at 7 and turns it off at 10. The timer was really a must since we travel sometimes. The timer I purchased will turn on and off two different times during the day. (So far, no problem with algae, but I'm borderline too little light already in my planted aquarium (low-light plants). If I need to have light for less hours, I would be able to have the timer turn on for several hours in the morning, and then turn on for several hours in the evening. That way we could still observe and feed our fish when we're there.
