Proper lighting on irradescent fish?

[Tetratastic]

My tank has the standard florescent bulb that came with the hood - but I have pearl danios which upon researching I know 'look best under proper lighting'. I cannot however find any information on what the 'proper lighting' actually is.

When the tank light is on the danios are pink to yellow, when just the living room light (hallogen) is on, they are a soft blue.

Is there a brand/type of bulb anyone would recommend? I would like to get the most out of the danios' pearliness if possible.

Thanks!

Daylight. Sunlight even.

The point source of solar light means that the rays are all parallel, which means that the interference patterns that create iridescence don't get blurred.

I was looking at my Rams in sunlight this afternoon and marvelling. Now with the sun down, under the fluorescent strips, they're just pretty...

I had a pair in a 55g with 2x40W NO fluorescents. They looked beautiful. However these were unusually pretty specimens to begin with, which I fed frozen brine shrimp and bloodworms, as well as Hikari Micro Pellets.

I've found it's the case with most fish that you get the most beautiful coloring when the fish are happiest and/or healthiest. Feeding foods they really like in an undercrowded, well-filtered tank is best.

I agree with the above statements...

I read somewhere that sunlight is a good thing for a fish room as it can add a new dimension to the view of fish every once in a while...where did I read that?

Unfortunately the sunlight in my apartment is pretty much blocked out by all the tall trees, so I guess I'll just have to take me fish as they are under the florescent bulb :)

Thanks to everybody for the info!
