best fish for bright lights

I'm planning to return to the planted tank scene, but this time with a little bit more equipment, time, and research. I definitely want a nicely aquascaped tank, but I'm worried about the effect of bright lights on the fish. I was first considering harlequin rasboras, but they have rather subdued lighting in their natural environments. Apparently the same holds for many popular fish, including neons.

So I'm curious, does anyone know what fish are naturally found in strong light? I'm also guessing that many planted tanks have much brighter lights than are found in many natural settings. Is this true? I'm hoping to find a good balance between natural conditions and performance.

And if there are no good fish for bright lights, is it reasonable to use high powered lights to grow the plants into a dense forest, then drastically dial back the lighting to maintain them in approximately their current states and add the fish at that point?

How much space do you have? If you have a reasonably large tank (say 40b and up), a school of zebra danios would make a stunning display. If you give them enough space, they are also very entertaining. Some rainbow fish would also work, though they'd require at least 55 gallons.

Actually whenever the sun shines directly onto the surface, natural light is a lot brighter than what regular artificial light can provide. But of course there are many factors. For example, if you are talking about a forest stream or deep or murky water, you may well be right.

I'm looking at doing 29 gallon. I live in an apartment in SF and expect to move within the year, so I can't get too carried away. I'm already dreading having to move the thing.

Makes sense. 1000 W/m^2 is a hard stat to beat. But a 40b is ~0.4 m^2 surface area. Some specs say 5W/gallon which would give ~500 W/m^2. But that seems like it could be way too bright for forest dwelling fish.
