No, I'm dead serious.
Packaging of a specific brand of moonlights say "promotes spawning". I've seen fish in a tank spawn w/o the use of these lights.
Other people say that they like and use the moonlights b/c of the look.
I have two fans built in to my canopy. The fans have blue LEDs, and barely light the tank at all. Those are my moonlights.
Sorry if you thought I was a jerk.
