Don't worry about it, Rusty. It is mostly old wives tales with no basis 
in fact at all. They do feel better if there are lots of hiding places 
to duck into if predators show up. [I never allowed cranes, bass or 
storks in my fishroom, though. :-)]

Lampeyes, in particular, seem delighted in high-light well-oxygenated 
planted tanks, but my Aphyos have never objected to 3-4 W/G, either.

Killies show considerable discomfort in bare tanks with unpainted 
bottoms and no place to hide. Extra light just makes them feel even more 
exposed. I don't blame them, but cutting light, plants and oxygen aren't 
the best ways to fix that, IMO.

Low light can interfere with photosynthesis of some flagellates, like 
*Oodinium* (aka Velvet Disease) so that may be why darkness for 
gestating eggs works better for some. I don't see a lot of difference 
there, either.
