Man that blows! Some animals are just a gamble that way. I have a foxface too and I'm lucky that he hasn't shown any interest in corals thus far. But I recognize that he might someday.
Is there anything else that might be the culprit or did you catch him in the act?
Someone stop me! Please! But... not just yet...
