Reported on dailystar.co.uk, according to new research from an Israeli university in which goldfish were given the keys to their own motorised tanks, it might not be as far-fetched as you think.  Scientists at Ben-Gurion University in Beersheba claim their new research shows a fish’s ability to drive a specially designed “Fish Operated Vehicle”.

The Times of Israel reports that the strange study consisted of six fish being chosen to navigate their way around a room in the direction of a 'reward'. 

Shachar Givon and Matan Samina, who were instrumental in the study, described how the process worked.  They claimed the fish could "operate the vehicle, explore the new environment, and reach the target, regardless of the starting point, all while avoiding dead-ends and correcting location inaccuracies."
