Camo Posted January 9, 2006 Share Posted January 9, 2006 Hey I have a 4ft display tank with black background and a yellowy light. I have white coral gravel and the white light reflects of the coral sand and makes it look yellow and the tank as well. The background does not do the fish justice. So my question is what is the best light and background to use of a display tank. It has all coloured fish in it. I was thinking maybe a blue light instead of the yellow one.
