Whale Sharks - In A Tank !?

Take a look at this stunning photo - whale sharks in an aquarium in Japan :






















Not so much cute as unbelievable - the world's biggest fish (up to 12m) in a public aquarium tank in Okinawa, Japan. That tank must be enormous ! Having done some research, apparently a few other aquaria has whale sharks too - Atlanta, Osaka - but this is still the best picture I think.
