What is the best lighting for an indoor aquarium, so that the goldfish keep their bright colors?

There is really no best lighting for an aquarium. It  really depends on your budget and how much you want to spend on  a lighting system. In addition to seeing the color of the goldfish, you have to keep in mind whether or not you intend to grow real plants.  A lot of people like to keep lighting that has a  color temperature range around 6500k, which is a white light similar to what you'd see during the daytime outside at noon.  A color temperature around 2500k will give a yellowish tint and make the colors look softer and more dull.  Whatever lighting you use, pick a bulb with a color temperature range around 6500k if you like that daytime look, which should also display the  bright colors of your goldfish well.

Thanks.  My aquarium came with an 8000k florescent bulb that I've been using, but I keep hearing so many stories of goldfish turning completely white even when using a florescent light.  I'm hoping the fish keep their colors forever.  They're fine now.  I don't mind spending money on a good light, as long as it works.  

I have read different articles on lighting but can't find any definitive answers.  I thought maybe UVA and UVB lights would be good, but not sure.

I keep plants in the tank, but they're just a snack for my fishes.  They look nice and have grown roots without me even trying.

You really only need UVA lighting for freshwater fish aquariums. UVA is the the visible wavelength of light while UVB light is invisible to the human eye.  UVB is used mainly if you have pet like aquatic turtles and reptiles  that bask in the UVB light to help them synthesize vitamin D3.

The lighting you have now should work just fine for both fish and plants.

Thank you. I might get one of those moon lights, but that would be just for looks.

I have an awesome light that promotes plant growth, and it also shows the colors of the goldfish perfectly! They're glowing red and white Wink It's a tropical bulb by Arcadia. You could take a look in the pet shops if they have them around there! Mine are pretty huge, and I need two of them, so they cost about 20 each.

I guess my original question was more like, why do I keep hearing stories of goldfish turning white?  Is there something I could be doing now to make sure they don't turn white in the future?  

They are very pretty now and have great colors, and I want to keep their colors by doing the appropriate things now, before any fading starts and before it's too late.  I would be sad if one day I woke up and they were all white, but I'd still love them.  Smiley

I have searched and read up on this on the internet, it seems to be related to good quality food and 'correct' lighting.  I have been feeding them good quality foods, and a huge variety.  And I hope my florescent light is good (8000k).

Nossie (or anyone), do your indoor fish keep their colors, even after growing large?

Of course! Smiley But I don't think you need to worry about goldies losing their color, it's usually happening when they're white at first but with some colored spots. Or black goldfish can start turning red after a few years, which is pretty common among other varieties but moors. So most goldies with black spots may end up all red or whichever the bottom color may be Smiley

My Berry is moving her red spots around though (I'd guess she's between 2-3 years old)! At first the headgrowth almost lost it's color, but it's back to be raspberry red again Wink And the spots are also developing farther down to her belly now Smiley
Some of my calico fish are also getting smaller white spaces, and aside from that, I only have one colored fish Smiley The pearl scales are still too young to tell whether the colors will stick or go.

Now, the old-man fantail in the 20gal is more than ten years old, he was originally a golden red, and has turned a slight bit paler through the years, but that's acceptable due to age. The tancho fantail who lives with him is completely white with only a red circle on the head, which has actually spread a bit more down to the eyes! He's still pretty young, but that coloration usually stays Smiley

Lighting on the other hand will pronounce the fishes' colors if you choose the right one! The one I have happens to be a type that makes reds and blues very strong Smiley So the calicos certainly look like they have blue skin Wink
And since you probably saw the thread about the yellow ryukin, he had been eating only algae for a long time, so he lost his color temporarily. I'd say the way the fishes' colors react is highly genetical and depends more on their genes than which diet they're fed, at least when considering a permanent outcome Cheesy

Thanks for explaining it to me!  It's always good to hear from someone with real life experience.  I was worried that they'd all grow up and look identical, but now I can relax.

So far their colors look great.  My shubunkin is especially fun to watch grow, because his colors are becoming more defined as he grows larger.   Cheesy

I have 1 shubunkin and 1 comet in my 75 gal tank.

I have 2 new comets in quarantine in a 10 gal. They are all about 2" (+ tail).

They are all gorgeous and so cute and fun and  lovable  Cheesy. I'm on vacation now and will post some pics next week. I should get an avatar too, when they're all together.

I'm not familiar with lighting, is this (the 6500k light) a fluorescent light?
Is fluorescent preferred to incandescent? Not sure what the proper lighting is for goldies and looking to purchase a tank + all the goodies Smiley

I have fluorescent light in my tank, it shows off the colors of the goldies and really helps the plants grow! Cheesy

Fluorescent lighting is preferred because it doesn't heat the water.
