However, one important thing to bear in mind: fish need a period of total darkness, no ambient room light, complete darkness. I wouldn't go less than 8 hours for this dark. And second, there must be room light when the tank lights come on and go off, to avoid stress on the fish from sudden light/dark. I am working on an article on light and fish eyes that will detail this more, but it is very important. In my case for instance, when the tank lights go out at 8pm in winter it is total darkness outside, and I have a fish room, so there is a wall light that is also on a timer to come on a few minutes before 8pm and remains on for an hour. At noon when the tank lights come on there is daylight from the windows.
This makes perfect sense to me. Right now the light comes on at 12:00 pm and goes off at 8:00pm. The sunlight is the morning prelight and then before the light goes off I usually have a distant lamp that is creating a smoothing end light. Heck I remember being in class watching a power point with the lights off. When they turned on the lights it sure was annoying. So I am sure it is the same with fish. I look forward to your article when you complete it.
So far so good. No issues with any of that stuff showing up yet. Just got done using some flourish for the plants. I will let yall know if anything starts up again.
