Do fish need light?

I've heard it has something to do with the fish's balance. I'm not sure though.
but why not a light? unless there is lots of outside light you won't be able to see the fish as well.

Bad info. Bad fishisme! Bad!!
Fish need light. People need light. Vegetables need light. Minerals don't need light because they are DEAD.
If you would like your fish to become minerals, then they do not need light.
Most species require day and night in a cycle similar to the wild if they are to remain healthy. There are alot of reasons, but here's the biggies:
It regulates their metabolism
It establishes a sleep/wake cycle
It provides vitamins & nutrients
It extablishes the cycle for beneficial bacteria
It establishes algae which some species eat
The fish who do not need light are deep ocean fish. These fish live at extremely high pressures and if you have a setup for fish that do not need light, you are an aquarium god and I want your setup (I have always wanted some creepy viperfish and glowy hatchetfish for my game room).
No, the light doesn't need to be on in an unplanted tank, but it makes it much easier to enjoy the fish.

You know what happens to fish that have no light?
Their eyes disappear, just like the fish in caves. This happened to my friends fish, it wasn't near any windows and the only light he used was a 60 watt lamp. he likes it dark in his house, says he sees the tv better. it took a long time, probably near a yr but it happened. He wasn't very observant of the fish, guess he was tired of them. Back then neither of us knew about doing water changes, so the only time he saw them was feeding time and I doubt he looked then.
I came to his house one day and looked at the fish and they had no eyes, none zilch. He thought it was cool that he now had cave fish.

Aqualung (let me guess, last name Rockbrain :joke: ),

It's common sense that animals who live in a natural environment should have that environment duplicated as closely as possible in captivity for good health... where do you get your info (since it's totally bogus and wrong)?
Please explain to me why fish don't need light? (or better yet go live in a cave for a year with no light and we'll see how healthy you are when you come out... we could make a game of it and have before and after pics).

I think people are getting confused over light (the aquarium light), natural room light, and total darkness. A fish tank in a room with a window that lets in light will be fine, the fish do not need the aquarium light on, they still will get day and night. If the tank is in a dark basement then, yes, the aquarium light will take the place of daytime.
The question wasn't whether or not the fish should be kept in a cave, the poster asked whether or not the tank light needs to be left on in an unplanted tank. The answer to that is quite simply, no.
Rockbrain, huh? :troll:
I guess I should get a light for my cannister filter to establish my cycle huh?

I'm sorry, I did not realize you were intimately familiar with the setup the original poster has that is being discussed.
The question was "Do fish need light?" (see title of post), not "Is Aqualung available for bad advice and crummy attitude?"
Since you are intimately familiar with their setup, I wonder why this person did not ask you for your advice seeing how you know everything about fish biology and how light affects it. I am guessing maybe they followed your pi$$ poor advice in the past and paid the price.
