Shy. I don’t know. They are very brave in holes in the coral. They will let you come right up and put a camera lens in their face. They do not shrink back in the least. They don’t come out either. Just their little head sticks out. Big eyes stare at you while you image them. So, it’s a surprise to see this guy out of the hole. But there he was sunning himself on the coral tempting some other fish to eat him. Not me. Too small to even consider a snack.
