Growing beans with goldfish? It's possible

The Hootie 1.0 Indoor Aquaponic System was able to grow a string bean with only about 100 grams of ornamental goldfish powering the train, Anacostia Aquaponics reports.

This string bean was just a test to see if they could grow a decent fruiting vegetable with this 29-gallon system. (Fruiting plants like string beans require more nutrients and are generally harder to grow well). Ultimately, this system is best suited to grow seven or eight quick-growing herbs and lettuces at a time because of the small-ish fish tank and wide media growbed.

They were happy to see that – despite its diminutive size – it was a crunchy and tasty little bean.
