A reef tank would be so much easier without these....or would it?

I can see it now,
"Hey fishless system, no problem, we have the finest maricultured fish poop in the universe, just 19.99 a pound"

I feel sorry for the scuba diver swimming behing the humpback whale, hope his bag is big enough.. LoL

Now that I think about it.
They will probably have two types.
One for herbivores and one for carnivores.
The diver collecting for the herbivores not to bad.
But the diver following the Great White shark for the carnivor version well WOW

I could not imagine having a reef tank without fish, they give so much character to a tank.
