in my country ure shark is called a river patin. so damn tasty it has to be my fave fish to eat because they have a lot of fatty deposits around the sides. steamed with soya sauce....mmmmm
Never heard of a River Patin, they're just called Iridescent sharks. They live for 20-50 years (Longer in captivity) and easily grow 3-4 foot and are natural school fish. Its best to have a minimum of 4 but this isnt always possible when they grow that large.
