Maybe it will straighten out some when I get old!!!Originally Posted by davidstcldfl
Yea, it does depend on so many factors. Light intensity, spectrum of light (there are studies on just the colors, weird but interesting), and probably things not studied like UV. Fish species, stage of life cycle, even genetic factors.Originally Posted by keith_r
Those new plasma lights mimic the spectrum of the sun pretty well, but nothing will match the sun's intensity.
Most spawning studies appear to be done with low intensity lighting. I think this all comes from the earlier studies in the 1950's when they associated spawning behaviors with the extra light from the moon during seasons.
