PlayTank Lab · AquariumOS
A fully smart home for your fish.
AI woven in: it understands fish, water, the tank — and you.
00 · Idea
It starts with the fish and ends with you
The living heart
Fish: living well, living happy
Fish can’t talk, but they never lie. Whether the water is right, whether they eat well, whether they’re happy — it all shows in how they swim. Everything we build starts there.
↓ The tank is built for the fish: whatever they need, it provides
Their whole world
The tank: the center of their life
Twenty-plus modules and open interfaces take care of water, food, light, flow and play — in three layers: survive, live well, be happy. One tank of water is a fish’s entire world.
↓ The more modules, the more AI can orchestrate
The bridge
AI: understands fish and people
It reads the water and the way fish swim, and speaks up for them. It understands a casual sentence and coordinates a dozen modules. Our AI isn’t bolted on — it’s built into every detail.
↓ The better it understands, the calmer the fish and the happier you are
The one who enjoys it
You: the joy that heals
Happy fish, happy people. Watch them chase the light, race for food, sway to the beat — and the day melts away. Company, beauty and calm are the fish’s gifts to you.

- 01
OSAquariumOS, our own operating system
An OS written just for aquariums — devices, control, interaction and intelligence in one.
- 02
HWDistributed modular hardware
Every module has its own chip: put it anywhere, it’s recognized on connect and updates over the air.
- 03
AIAI across the whole chain
Answers, disease prevention, tank-mate advice, water alerts, great photos — it even voices what the fish need.
- 04
BusOne unified bus
One cable links every module. Plug in and go — no separate wiring.
- 05
SafeBuilt-in fault isolation
One faulty module never takes down the rest.
- 06
FlowScene-based teamwork
Time, temperature, water quality or device state trigger modules to work together — AI helps you plan.
- 07
VoiceNatural voice interaction
Just chat with Tank Bro and Fish Sis to play, automate, even program the tank.
- 08
AheadTrends, not just thresholds
AI reads long-term data to adjust early and gently, not only when it’s too hot or cold.
- 09
WatchAlways watching the fish
Beyond water quality, AI watches how the fish swim and eat — changes get noticed early.
- 10
YouTiered control — you always decide
Automation and AI work under your authority; key actions can ask for your confirmation.

03 · Modules
What modules are there?
Original, carefully designed, many styles — plug and play.
Fish · Alive
Clean water, oxygen and healthy bacteria keep fish alive
A tank of water is a fish’s whole world. The Integrated Pump Bay combines UV sterilization, water level, temperature and water-quality sensing, circulating day and night. The Self-Cleaning Fleece Filter advances its own fleece, cleans its intake and skims oil film and leftovers. The Trickle Bio House offers more media options and gentle intermittent aeration; the Waterfall Bio House uses AI-coordinated pumps for stream-like oxygenation.
Fish · Living well
The right temperature, balanced food, good light
Once they survive, they should live comfortably. The Heat & Cool Base not only holds temperature but mimics day, night and seasons. The Universal Feeder serves meals on time and keeps food dry; the Precision Feeder also doses medicine and supplements on schedule. The Liquid Doser adds daily trace elements, the Water Change & Aerator swaps old water for new with millimetre-level top-up, and the Full-Spectrum and Sunset Plant Lights recreate a whole day from dawn to dusk.
Fish · Happy
Flow to swim in, light to chase, fresh air — and something to play with
Honestly, fish get bored too. The Flow Simulator moves up and down to recreate a living stream. Auto Air Exchange brings in fresh air as conditions change. The Roaming Spotlight sweeps the tank so fish have light to chase — and you can program it with AI. The Fish Teaser moves little props in the water; lower a tiny mirror and a betta will perform for ages.
You · Alive + well + happy
See it, play with it, talk to it, stop worrying
For people, joy is the part you can’t do without. The Smart Control Hub is the tank’s cockpit — glance up and you know how the water is and how the fish ate, with instant alerts. The Underwater Camera puts you inside their world, snapping the best moments automatically. The Programmable Ambient Light changes mood with one sentence. Smart aquascape panels — brick panels, pegboards, even your own 3D prints — make the tank a new world whenever you like. And Tank Bro and Fish Sis are always up for a chat.

An idea is enough
No electronics or coding needed — we help all the way.
Wave makers, pumps, lights, feeders — any aquarium device becomes a standard AquariumOS module once it carries our standard control board, working with every other module and with AI. Even aquascape panels: a little 3D modelling and printing is all it takes.

How to connect
- 1Fit the standard module control board
- 2Describe what it does and its parameters in the module’s built-in description
