I have a one foot Zebra that is also very well behaved. My coral banded shrimp push him around whenever he gets nosy. Actually, my Scopas Tang and Flame Angel also go out of their way to push him back into the rocks whenever they see him. Quite neat to watch actually. The two fish 'broadside' him, he gets annoyed, and finds another hole to come out from.
He seems to be very agile too; never knocked over any rocks or corals. The only drawback I can see with him now is that he needs to eat a lot, and thus is a heavy polluter. But well worth it, IMO.
