About
About YuzhaLink
YuzhaLink is a smart-aquarium platform and hardware brand — sensors, controllers, and the software that runs them. It is operated by PIFISH PTE. LTD, founded in Singapore in 2021, with its lab and engineering team in Beijing.
What we build
We build the hardware and the software as one system, because the problems that matter in an aquarium happen between them: a reading that drifts, a pump still running after that reading went bad, an alert that arrives too late to be worth having.
Four things, one platform:
- Devices — sensors, dosers, pumps, controllers and power modules that report both their readings and their own status.
- Monitoring — readings kept as history, not just a number on a screen right now.
- Automation — control logic that acts on those readings.
- Aquatic knowledge — the reasoning behind the defaults, written down, so you can change them on purpose rather than by guesswork.
Everything runs from one account, in English or Chinese.
The YuzhaLink family
Four names, one ecosystem. Here is what each one actually is, so you always know which you are dealing with.
YuzhaLink
The consumer platform and our own hardware line — devices, monitoring, automation and aquatic knowledge for people who keep their own tanks. This site, the app and the shop are all YuzhaLink.
YuzhaLab
Our laboratory: the test systems behind the platform, and the aquarium-related research we publish.
Visit YuzhaLabYuzhaMatrix
Our platform for businesses — fish shops, breeding farms and other operations running many identical aquariums. Deployed locally rather than in the cloud, for cluster deployment and centralized management.
Business enquiriesAquaEco
A high-end aquarium hardware brand whose software integrates with the YuzhaLink platform ecosystem.
How we work
How we build and test
We are a small team — hardware, firmware, aquatic science and software — and the same group builds all of it. Devices run on real systems in our Beijing lab before they reach anyone's tank. We test on water, not only on the bench.
A real lab, not a slogan
YuzhaLab keeps working aquarium systems in Beijing. Devices and control logic are exercised there first.
One team, sensor to app
Hardware, firmware and software sit together, so a problem is not handed between vendors before anyone fixes it.
Written down, not folklore
Setup, automation and troubleshooting are documented, and the documentation is part of the product.
Since 2021
We have been building aquarium hardware and software for five years. Today's platform is the result of that, not a first attempt.
Who we build for
Two kinds of aquarium, two different products.
If you keep a home aquarium or a reef system, YuzhaLink is for you: your own devices, your own account, monitoring and automation under your control. Start with worked examples from real systems, or read the documentation.
If you run a fish shop, a breeding farm, an aquaculture operation or a research facility — many identical tanks managed as one fleet — that is YuzhaMatrix, deployed on your own premises rather than in our cloud. Write to us and we will tell you where it stands.
Fish rooms sit between the two. Which platform fits depends on how the room is run, not on how big it is — so ask, and we will say plainly which one we would put you on.
We work in English and Chinese: the company sells internationally from Singapore, and most of the engineering happens in Beijing.
