When I built my pond, I couldn’t afford fancy fish like Koi, so I went to the pet store and bought 10 tiny “feeder fish” (the kind you give to snakes and frogs) for 23 cents each.

Two years later, there’s still nine of them and they’re all big and friendly (and still way cheaper than koi).

Here’s 30 seconds of goldfish relaxation pond-side. Background music provided by a mourning dove above the pond.
