Years ago, my girlfriend (now my wife) bought a small five-gallon aquarium… and promptly set it up on the floor of her apartment.

“Why did you put it on the floor?” I asked.

“So I can see the [Fishes] properly,” she smiled.

Never did I understand how she kept her “floorquarium” going, until the day we flew to Vietnam to visit her hometown. Searching for interesting Fishes in homes, markets, ponds, and streams, I realized that most Vietnamese people don’t keep aquaria – they prefer Zen-like, planted ponds.

Thus, the mystery of the “floorquarium” was finally solved. In the eyes of my wife, it was a pond!

VIEW FROM THE TOP

Though the majority of ornamental Fishes end up in aquaria, Koi, Goldfish, and a few of our other finned friends have been selectively bred to look striking from above. For generations, these Fishes have been kept and bred in ponds.

Not everyone has the space to keep Goldfish and Koi though, especially since Koi can grow three feet long. For pond-lovers with limited space and a modest budget, there are pond pots – vessels made of plastic, concrete, or ceramics that can house not just Fishes, but both aquatic and terrestrial plants as well. These are crazy popular in Vietnam, a country with a historical affinity to combined gardening and fishkeeping.

Long known to sustainable agricultural enthusiasts, Vietnam’s traditional VAC farming system is a traditional food production system that combines livestock farming, aquaculture, and horticulture. The initials VAC (Vườn Ao Chuồng) can be translated as garden, pond, and livestock pen.

For centuries, Vietnamese (especially those living near Vietnam’s most fertile regions – the Red River and Mekong Deltas) have cultivated Carp and Catfish in ponds. In the same plot, they cultivate fruits and vegetables while keeping Pigs and Chickens.

A portion of the fruits and vegetables are used to feed the Pigs and Chickens. Their poop is then gathered and chucked into the pond, where the Fishes are fattened (just don’t think too hard about what they eat). Though this idea might be a bit hard to swallow for some, this closed-loop system is an amazingly efficient way to produce food.

Perhaps the Vietnamese people’s love for ponds stems from this age-old tradition.

INSPIRED BY TRADITION

In Vietnam, we visited numerous homes and establishments where pond pots took pride of place. My wife’s family also has a pretty cool pond pot at home. With miniature limestone cliffs coated with moss, it looks a bit like Vietnam’s Ha Long Bay or our very own El Nido.

Pot Pond. The beautiful pot pond of my wife’s family in Vietnam features tiny limestone cliffs covered in
moss, ferns, and bonsai ficus plants. Tiny ceramic bridges, temples, and pagodas add a touch of tranquility, while Guppies and Swordtails add color and motion. (Gregg Yan)

It even has nifty ceramic bridges and tiny pagodas, like a mountain diorama come to life. Pond pots liven homes while helping regulate temperature (notice how it always seems a bit cooler near a pond). Being half-terrestrial and half-aquatic, pond pots deftly combine gardening, fishkeeping, and diorama building into a single hobby.

You can adorn your pond pot with tiny glazed figures of people and animals, plus structures like houses, temples and pagodas. You’re limited only by your creativity when making miniature scenes. There are even little boats (complete with ceramic fishermen) that can float across your pond.

Of course, what brings ponds to life are the animals – in my wife’s family’s case, a colorful, fluttering assortment of livebearers like Guppies, Platies, Mollies, and Swordtails.

Lovely Livebearers. Livebearers like Mollies, Platies, and Swordtails are herbivorous and able to graze on the algae and microorganisms that naturally thrive in pot ponds. They multiply quickly, making your stock self-sustaining if well-tended. (Gregg Yan)
Guppies Galore. Nearly every Fish store in Vietnam offers Guppies, which come in a wide range of colors and sizes. (Gregg Yan)
Pond Plants. Ngoc checks out buckets brimming with lotus, water lily, papyrus, and water lettuce at the Mindanao Avenue Garden Center in Novaliches, Quezon City. She eventually picked out a nifty lotus plant.

FLORA AND FAUNA FOR POND POTS

Three Years and Growing. Our modest pot pond in Metro Manila is made from an old but sturdy plastic Megabox. Though mostly obscured by variegated and neon pothos, it’s home to dozens of tiny Shrimp, colorful livebearers and a grouchy, two-year-old freshwater Goby. Want to complement your aquaria? Then try setting-up a pot pond today. (Gregg Yan)

In Vietnam, pot ponds usually brim with livebearers, which makes perfect sense. They’re inexpensive at only around PHP 10 each, hardy as hell, eat anything (algae, diatoms, bacteria, and most especially the Kiti-kiti or Mosquito larvae bound to settle in the pot), and multiply swiftly to keep Fish populations relatively self-sustaining.

For flora, you’ll have thousands of options. Terrestrial plants range from delicate forest orchids and bromeliads to hardy and fast-growing vines like golden pothos. Water plants include the usual aquatic plants like bacopa, cabomba and vallisneria, plus floaters like water lettuce and duckweed, which you can fully appreciate from above. Larger, deeper pond pots that can accommodate a muddy substrate can include a plant special to Vietnamese – the lotus.

“The lotus is Vietnam’s de-facto national flower. It symbolizes purity, resilience and the calm and noble spirit of our people,” explains my wife Ngoc. “We have a saying in Vietnam: The lotus flower lives in muck – but it never ever reeks of it.”

Though not yet as popular in the Philippines and other countries, the creative possibilities offered by pot ponds are endless. I first likened them to a “poor man’s Koi pond” but found that their allure is altogether different and far more complex, requiring an understanding of both aquatic and terrestrial ecosystems.

Inspired, I built a small pot pond out of an unused plastic Megabox back in Manila.

That old “Floorquarium” really made me realize how there’s so much more to fishkeeping than viewing Fishes eye-to-eye. Truly, the view from the top is every bit as interesting.

Pinoy Made Pot Pond. This custom-built pot pond’s ready to go. “It took me months to build and finish this one. I even built the base out of waterproof cement,” shared this talented Pinoy craftsman at the Mindanao Avenue Garden Center. (Gregg Yan)
Simple Setup. We saw this small pot pond in Pleiku, deep inside Vietnam’s Central Highlands region. It’s made from a big ceramic plant pot and features a customized filter and some-planted flora. Red Swordtails, silver Balloon Mollies and even a green Glofish Danio bring it to life. (Gregg Yan)
Free Plants. Zoom off to your nearest public pond or lake and you might just find some free plants for your pot pond. Floating plants in particular multiply exponentially, so you can probably fish out some green freebies with a long stick (just don’t fall in). Shown are lotus plants, water lettuce, duckweed, and hornwort at a pond in Metro Manila. (Gregg Yan)
