A digital design company in the Netherlands has developed a prototype chip tray that moves on wheels in response to the movements of the fish.

The company, Studio Diip, launched the idea in the crowdfunding site Kickstarter, which has begun over the Netherlands.

Thomas De Wolf, co-founder of Studio Diip, told the BBC how the device works, and measures to protect the welfare of the fish.
