Best use of a backyard: aquaponics garden + tiny house?

[epitaph]

I don't own a property yet. This is more future planning/idea generation/dream...

I always wanted to have a garden in my backyard like my parents. A year or so ago I heard of aquaponics gardening, and it made sense...an ecosystem where the plants and fish grow symbiotically. Not only can you grow fresh, organic vegetables, you can harvest your own fish too. What's not to like, esp for a Bangali or anyone who likes fish.

Idea sounds nice, but has anyone seen this in practice by any chance or have an opinion?

And regarding the tiny house, it'd be for rent. Or could be an office space or a man cave.
