So far, all of the ones that I've seen are too big for a 40g unfortunately.
+1 a 40g tank is MUCH too small for ANY Angel fish except for the Dwarf Angel fish.
I've had a Coral Beauty and a Flame Angel, both Dwarf Angel fish and neither of them picked at any of my corals.
I've seen large 200+ gallon LFS tanks with large angel fish that didn't pick at the corals either, I think it has alot to do with making sure the fish are well fed. If they arn't hungry they wont go "Looking" to make a meal out of your corals.
But then again, there are 2 to fish that are the same, so it's a crap shoot really.
