Genicanthus species, as previously stated, are the only guaranteed ones. Many dwarves (especially the potteri/bispinosus/multispinis complex and the argi/aurotonotus/acanthops complex) are relatively safe. I've heard a lot of success with ferrugata/loriculus as well. Avoid bicolors, though the similar joculator seems to be, from most reports, very well behaved.
