Fishless system?

[Quagmire]

I saw an article about feeding corals a few months back.They did a small test with 2 tanks,one with just light and one with light and food.Added a number of differant corals,then compared the differance after I can't remember how long.Huge differance in growth rates in the fed tank.I'll see if I can find it and I'll post a link to it.But it leads one to think that a tank with coral friendly fish would be the way to go.You feed the fish,the corals eat too,then eat again when the fish take their morning constitutional.
