In their natural habitat the substrate is sand for almost all cory species, at least the ones I have studied. But they will be OK in your tank, as the substrate is not sharp edged rock but pebbles. I have small-medium grain gravel in my tanks and they seem to be doing fine. As an earlier post said, don't overfeed as the food will get down within the substrate. And maintain a regular partial water change schedule (weekly is good) and vacuum the substrate each time.
You need some plants though, for the cories and the angelfish. And a piece or two of bogwood lying down so the corys feel more secure. They do not like empty tanks. You can get some good ideas by checking the photos of the members' tanks that are in the "Freshwater Fish Pictures and Videos" part of this forum.
