London – Want to stop your goldfish getting bored? Simply take it for a walk.
This Aquatic Perambulator is the brainchild of 60-year-old Mike Warren-Madden.
The former metal worker came up with the idea seven years ago and spent thousands of hours design his device.
He designed it because he wanted to help his pet fish Malcolm lead a more exciting life.
Malcolm went on to live to 11 thanks to his adventurous lifestyle, which included trips to the pub and walks around town.
Mike now has a new fish, Coco, and hopes an investor might help him motorise his invention.
