Moorish idols are very particular nutritionally in their natural environment. As some have said, we can get them to eat in captivity but we don't seem to be able to meet their nutritional needs. In the wild, they eat sponges. Not so easy in captivity to provide that as food. I think that we should attempt to allow our captive friends to live as long or longer than they would live in the ocean. So, with that in mind, Moorish Idols are probably not a fish of choice for the vast majority of aquarists.
