Do you guys run blue lights at night or pitch black it?
I usually let it go black but last night I turned on the blue lights and it looked nice but also seemed to confuse the fish. What do you all feel is better?
My LED's have several lunar settings; Full Moon, Half Moon and Crecent Moon. I vary it up nightly. The fish suffer no apparent ill effects. Each fish retreats to its own sleeping cave, crevace or DW piece.
