New Feeding Guideline:

Each cube of frozen food you feed per day needs 12 square inches of screen, with a light on both sides totalling 12 watts. Thus a nano that is fed one cube a day would need a screen 3 X 4 inches with a 6 watt bulb on each side. A larger tank that is fed 10 cubes a day would need a screen 10 X 12 inches with 60 watts of light on each side.
