It would be interesting to see what response there is to levels of UVB in our reef aquariums. Clearly, scientifically and anecdotally, lighting plays a dramatic role and clearly UV wavelengths, at least those readily available to us reef aquarists do affect, at least, coloration. If you go to this thread https://www.reef2reef.com/threads/reboot-with-leds-after-many-many-years-out.344915/ and head to post #20 you can see my anecdotal observations regarding light and its effect on the coloration of at least one acro sp in my tank.
