Answer:You hide it in a Mega Aquarium..and then add three more:
It certainly beats watching a lonely goldfish swimming round its tiny bowl.This is one of the world's biggest fish tanks - so big that it's even been named the Kuroshio Sea.Located in the Churaumi Aquarium in Okinawa, Japan, the enormous tank is some ten metres deep, 35 metres wide and 27 metres long.
It holds a staggering 7,500 tonnes of water - roughly equal to three Olympic-sized swimming pools. But the daddy of them all is the world's biggest fish, the whale shark - which can grow to be 12 metres long and needs a quarter of a tonne of food every week.
Only three aquariums in the world have tanks large enough to house these giant creatures.
