The diet of the Moorish Idol fish differs depending upon if it is wild or in captivity. Wild Moorish Idols eat things like sponges, tunicates, coral polyps, and other invertebrate creatures. When kept in captivity they tend to be picky and will either eat nothing (which is the most common behavior) or everything. This is probably one of the main reasons that they have such a low life-span in captivity.
