I just asked this question and here's what I got.....It depends on what kind of corals you're talkin' about. Softies, Zoas, Hard corals, etc.
Some corals create their own food through specialized algae that they make on their own from interaction with light.
Figure out which kind of corals you want to keep and then go to the appropriate forum and the folks that are experienced with those will be a great help to you. Hope that helps !
