Actually, I've seen pictures of them starving in full-blown reef aquaria. Mine never ate any corals that I saw in captivity and the corals just aren't really necessary with this fish, if you get them onto other foods. I think that it is much better to at least keep them out of a reef tank long enough to ensure that they are eating alternative foods and that they've put on enough weight that they are no longer in danger of immediate starvation. And, honestly, by that point the corals are optional.
BTW, the aquarists having the greatest success with this species are _not_ maintaining them in reef aquaria.
