I guess you can say that each and every fish in the Aquarium of Western Australia is a saltwater fish, ranging from gigantic sharks and rays to small and colorful tropical fish. Sao Paulo, on the other hand, has it's giant oceanarium tank, also containing many saltwater species. Which aquarium will lose its plaice (get it? the fish? plaice?) in the competiion? Expect to see many more puns in the cup.
