Tony Robbins hits these special golf balls into the ocean that dissolve into fish food

When Tony Robbins whacks golf balls into the Pacific off the porch of his Fiji home, he's not just living the peak luxury lifestyle, he's feeding some of the local fish.

Business Insider recently traveled to Robbins' Fiji resort Namale, where the world-famous life coach was hosting the winners of Shopify's Build a Bigger Business competition. He gave us a tour of his private residence and showed us his stock of fish food golf balls.

Barcelona-based entrepreneur Albert Buscató invented the "EcoBioBall" in 2008 and began selling them through his company Albus Golf in 2010. He sells boxes of the balls on his website (100 of them will run you $116), and major clients include cruise lines and resorts like the Four Seasons.

Buscató had the EcoBioBall independently tested to meet the Organization for Economic Cooperation and Development (OECD) guidelines for biodegradability and non-toxicity. Fish can get at the ball's fish food core after a day and a half, and even if no fish swam by to snack, the ball fully dissolves within 28 days in all water temperatures. Following is a transcript of the video.

Tony Robbins: This is another hangout area that we really love. I opened this up because I have "fish balls." I have these golf balls that are full of fish food, and so we use these as holes here and we come out and knock balls here. These fish food ones - you knock these out and then they dissolve in the ocean and provide the food. So, they're ecologically sound, but also the fish love it. It's kinda cool.

Graham Flanagan: So, that's full of fish food?

Robbins: That's full of fish food, so it's kind of fun.

Billy Beck III: Take a bite of it! [LAUGHTER]

[They're called EcoBioBalls. A Barcelona-based company started making them in 2010. The ball's core is made of 100 percent natural fish food. The balls start to dissolve after 24 hours. Fish begin eating the food after 36 hours. The balls fully dissolve after 28 days. The balls passed independent tests for biodegradability and non-toxicity. A box of 100 balls costs $116. The balls don't fly quite as far as normal golf balls, but that's a small price to pay when you're feeding fish!]
