Giant Arapaima Fish
This giant Arapaima fish is one of the largest freshwater species in the world and a bizzare one at that! In this picture, a diver shares a tank with the adult Arapaima at an aquarium in Manaus, Brazil.
These species can reach lengths of up to 10 feet (3 meters) and weigh up to 400 pounds (180kgs).

From the scales and body shape, this looks like a member of the carp family.
