Do light affect the life/health of fish?

[BlackShark11k]

i think it really boils down to the species in question. most south american fish seem to live at very low levels where virtually no light is present, like hoplias catfish and rhombs, but not all of them like angelfish and neon tetras which i do believe inhabit shallower areas with some sunlight.

in contrast, african cichlids live in quite "well lit" areas.

So lets say you have fish that come from well lit areas, like cichlids, and you don't light your tank...

What affects would this have?

 

[BlackShark11k]

I don't think much would happen over a short period, like say a week, since I used to keep my tanks in my basement fishroom which had no windows and i didn't light them when i left for vacation...

but long term? hmm. they would probably get kind of pale i suppose, but honestly im not sure.

Other than coloring, I wonder what other effects this would have.

remember that there are other sources of light besides sunlight and aquarium lights

Ok, but if you have NO light at all what would the affects be?

i don't understand the point of your questioning, what if i blinded an animal or you? you would try to make it by on your other senses your may or your may not survive.

if you want to know what happens down the road eventually fish that live underground evolve and lose there eyes and alot get pasty looking.

If you took your tank, and put it in your shed and left it in there for a year, and you maintained it with absolutely no light what so ever, do you think your fish would survive?

Animals and people are different than fish. Completely different than fish.

Fish that evolve and lose their eyes takes YEARS. HUNDREDS OF YEARS.

Like I said, go keep your fish in a shed. While they are in there, let me know when they lose their eyes.

I am asking other than getting pasty and finding other ways to function around the tank, what else does it effect?

Do they eat less, do they ear more, will the tank stay as correct as it is, will bacterial properties change, will the fish have health problems?

down the road meant thousands of years.

i suggest you find out the animals your interested in and research it. the type of fish makes a huge difference. the type of bacteria makes a huge difference.

with the information you provided you can only say generally the animals circadian rhythm will be affected. also light is generally negative to free floating bacteria.

and then when you find out your animals unless there has been a study or natural evolution of the fish in a related environment, you will have to do your own research.

your question has no real answer, like if you asked "a man goes jogging at night what happens?."

Why did you even bother posting? You knew my intentions of this thread the entire time. It is a question that other people have probably wondered as well.

There are so many questions on here that have no real answer, yet people continue to reply. It's just something to wonder about.
