The fish in the castle moat
The fish that you'll see in the castle moat below you as you cross the bridge to the castle are carp. You'll notice that the moment you tread on the bridge the fish will come to the surface and gape at you. It is sometimes thought that they are doing this as they need air, but this isn't the case they’re begging, just like a dog might do at the table. There are plenty of nutrients in the muddy moat waters, even though it may not look like it, and so we ask visitors not to feed the fish.
