Foxface's are very sweet fish, great algae eaters and it would be hard to get stung by this fish, they arent aggressive fish, they will actually be the first ones to hide and camo! i think its VERY hard frommy personal experiences for any other fishto even get stungby them, my stingrays, and shark ran into mine 1000 times ,nothing ever happened. Im not saying dont be carefull, but i wouldnt worry so much, they do however grow very fast.
Good luck with him !!:bounce3:
