You may be right about maintenance but, I would have to agree with the others. If you don't have too high of a bioload now, you will when the tang and foxface get bigger. In fact that tang will quickly outgrow your tank, in my opinion.

With that said, I also can't imagine feeding my 75g a whole cube of anything and then some. That is more than twice what I feed. My fish are healthy and a touch chubby. I use flake food five time a week. Mysis once or twice a week. Cyclopeeze once or twice per week. I cut the cube in half, rinse it losing some of the food and the cloudy water, and the feed it right in front of the fish. Almost nothing hits the substrate. It is completely gone in 30 seconds.
