Wow! This is amazing.
The video below clearly shows an orange-dotted tuskfish using a rock to help open a small clam. First he digs it out of the sand, then swims along, looking for a rock to use for opening it.
Pretty amazing, considering the fish hasn't much to work with - hand wise, or tool wise.
