Can Zebra Danios breed like this?
 
If I put them in a breeding box and have the eggs go through the grid and settle at the bottom of the breeder? Do you think this could be successful?

I don't think it would work. Female danios are egg scatterers and the males follow behind fertilizing the eggs. It seems to me that they'd need some swimming room in order to accomplish this.

I agree - a breeding box is just too cramped. A better idea is to get a nice, thick layer of something like java moss covering the floor of your tank. You could even lower the water level a bit to prevent the adults from eating the eggs as they drop. Of course, for the best hatch rates you'll want to remove the adults and any other fish after the eggs are laid.

How do I know when the eggs have been laid?

You'll have a very big bellied female who suddenly goes from very fat to slim in body. Not sure if it's something you'll be able to witness unless you sit in front of the tank 24/7
