Someone from the Musée océanographique de Monaco had a run in with a Napoleon wrasse on a reef. These fish can be fairly large and of course, underwater, they appear to be even larger. Fortunately the fish ate the camera, then spit it out after finding the taste and texture less than desirable.
I’m not a fan of Monaco, but I do love the aquarium at the museum. They renovated it a few years ago, but still managed to keep the old school feel to it, with collections from around the world.
