Was reading a few papers on light Wavelength while debating how to light a fish QT.
My questions are is there a Wavelength of light that allows for easier viewing of tissue damage. Tissue penetration is greater with higher wavelengths. But the absorption of light for hemoglobin is greater at violet. Would using say 660nm allow one to visually see damage at an earlier progression of disease than say 390nm?
A study on 660nm found that fish eat more readily, found no correlation with growth rate. Has anyone used red light on fish not eating in qt, and found a positive feeding response.
Lastly, are the studies on red light and tissue repair.

Would even a small effect be a positive one?
What would the negatives be?

. I would imagine under certain light conditions it would be easier to see flukes, ich, or velvet, and possibly any other bacteria diseases or open wounds. To my knowledge most people don't do a lot with qt lighting because it's not needed and they like to let the fish relax. Also lighting degrades cp one of the commonly used medications in qt procedures. I can't imagine lighting having an effect on the fishes appetite though. Maybe one of the more experienced reefers will have some more input.
