Zen Aquarium is a family-run Australian aquarium business that has served the fishkeeping community for more than 20 years from Paddy's Markets Flemington in Sydney.
For years, we focused on offering healthy, high-quality fish to local customers at fair prices. Then, during the COVID-19 pandemic in 2021, we made the decision that would define the next chapter of Zen Aquarium: taking our business online. It was a move born out of necessity, to keep our family business running, but it opened the door to something bigger: the ability to ship our fish to customers across Australia.
Today, Zen Aquarium specialises in Koi Fish and Goldfish, backed by our own range of Zen Aquarium Fish Food. We also offer a changing selection of other freshwater favourites, including Guppies, Platies, Corydoras, Bettas and Australian Native Tandanus Catfish, depending on availability.
From a local market stall to a nationwide live-fish delivery service, one thing hasn't changed: we're fishkeepers first, and we genuinely care about every fish that leaves our tanks.

Fantastic shop!
It's hard to find good quality oranda goldfish in Sydney, but these guys have the best stock, and always something new.
Their service is fabulous and prices are really good compared to your average pet store who sell poor quality at high prices.
Definitely recommend!

Love this place and the fish here is much healthier than the one in the shopping centre. I have came to this place for so many times. Loyal fan!

Quality fish with huge amount of choices. Bought several fish for two times and no problem at all. The price is very reasonable. Those who bought the fish and died not long after that, you should check the nitrogen and nitrite before you give a one star view to harm a good seller like this one.

If you're into aquariums or just getting started, you have to check out Zen Aquarium. Their team goes above and beyond with genuine, friendly service and deep knowledge about fish care. I was lucky enough to pick up the most breathtaking Oranda—truly a centerpiece fish—as well as some other healthy, vibrant additions for my tank.
The quality of their fish is unmatched, and you can see they’re well cared for. Whether you're a beginner or a seasoned aquarist, Zen Aquarium is the place to go. The variety, the health of the fish, and the staff’s passion really make it stand out.
I’ll be a regular from here on out—and honestly, you’re missing out if you haven’t visited their stall yet. Highly, highly recommended!

I had a fantastic experience with Zen Aquarium! I bought my goldfish online and the whole process was smooth from start to finish. The fish arrived healthy, active, and exactly as described. You can really tell they care about the quality of their fish and customer service.
Packaging was secure and professional, and delivery was fast. I also appreciated the helpful communication and updates throughout the order process. My goldfish settled into the tank beautifully and looks amazing.
Highly recommend Zen Aquarium to anyone looking for healthy fish and reliable online service. I’ll definitely be ordering again!
