Let there be light!

This is my first post in these forums.
I wanted to find out about 'lighting' for my tank, which has only artificial plants,but 20 fish, in an Aquaone AR850.
after reading this post, i wonder if i have chosen the CORRECT forum for advice.
The original poster asks a simple question only to be answered with stupid, joke type answers.
IS this forum dedicated to fish keeping, or keeping JOKERS???
:mad2:
Well, a sense of humor helps. Not just here but in all areas of life generally. So "easy60man", my first advice to you? Take it "easy". Your first post doesn't have you starting on the right foot, and the "grumpy old aquarist" forum is a few clicks down the web.
I keep my posting lighthearted because I've learned otherwise the people who take themselves too seriously get bent out of shape and start being snide and offensive (see above), especially when they are wrong and can't back up their argument with facts. That leads to personal attacks, flame wars, complaints to mods... the usual forum politics.
Now on to the real topic. Light.
By stating that fish need light (well maybe not cavefish and those living at the bottom of the ocean, they have ADAPTED to live without it, and are NOT case in point why "all fish don't need light"), I am just trying to say that if your fish come from an environment that has light, they will benefit from a tank that provides light.
Fish tanks are typically not situated in front of windows, where sunlight could provide appropriate ambient light. Also to be taken into consideration is the position of the tank in relation to the sun. My tank faces the west side, and receives little light until late in the day.
All light is not equal. Sunlight provides things that flourescent lights and other forms of residential illumination do not. That is why some lights are more expensive than others. Many tank light systems mimic the spectrum of light afforded by natural sources, and this is desirable.
Your fishtank is a mini ecosystem, complete with biorythyms, microfauna, and organic chemistry. This ecosystem is regulated by natural changes and rythyms governed by (drum roll please) light! Some fish (many actually) will only breed or spawn if the "days" are a certain length. WHY? Because nature has instilled in that species a disposition to do so because their young have a better chance to survive during that time of year.
I have yet to hear a reasonable argument for the "other side" but I'm waiting! And NO, the "I keep my poorly treated fish in an unlit unheated garage and they don't die too much" is not a reasonable argument why fish should be kept in the dark.

Thanks Sully, good to get another voice of reason here. I'm not sure about the cycling thing, I thought a light schedule was desirable during the cycle, but maybe I am confused about the role it plays? Maybe with all those quick BioSpira cycles the art of stabilizing a tank naturally is obsolete!

Good, less waiting, more fish watching!
