Dangbei has shown off the Smart Fish Tank 2S Ultra, a smart aquarium that wants to take fish-keeping off your to-do list. It uses AI image recognition to identify fish species, size, and count, then adjusts feeding, lighting, water flow, and sterilization on its own. It also watches water quality in real time, which is the sort of upgrade that sounds indulgent until you remember how often aquariums fail because someone forgot a tiny, wet ecosystem needs constant attention.
The pitch is simple: less guesswork, less maintenance, fewer dead fish. And while smart-home gadgets often overpromise, aquarium automation has a clearer use case than most – water chemistry does not care how busy you are. That puts Dangbei in the same broad lane as other connected pet devices: convenience first, with just enough intelligence to make the hardware feel less like a toy.
AI controls feeding, lighting, and filtration
Once the system identifies the tank’s inhabitants, it automatically tunes the routine around them. That includes feeding schedules, illumination, water circulation, and sterilization, plus alerts when water conditions drift away from the target range. The filtration setup is split into dry and wet zones and combines mineral and biological cleaning, with optional UV sterilization for extra help.
Dangbei says the tank uses activated carbon and nanoporous filter materials to remove ammonia and nitrites, which are among the usual villains in a stressed aquarium. Two pumps handle circulation at up to 350 l/h each, and the company claims the system stays below 30 dB – quiet enough to be background noise rather than a constant appliance audition.
A 32-liter tank with app-friendly hardware
The Smart Fish Tank 2S Ultra has a 32-liter glass body and full-spectrum lighting spanning 380-730 nm, backed by 45 LEDs for both plants and ornamental fish. For remote control, it supports Wi-Fi and Bluetooth, and it charges over USB-C, including use with an external battery. In other words: the tank is designed to keep working even if you move it around or want a less tangled setup.
- Tank volume: 32 liters
- Pump output: up to 350 l/h per pump
- Noise level: under 30 dB
- Light range: 380-730 nm
- LED count: 45
- Auto-feeder reserve: up to 180 days
Price and release date for Smart Fish Tank 2S Ultra
Dangbei has set the price at 599 yuan, with sales starting on 26 April. The long feeder reserve is the most eyebrow-raising part of the package: up to 180 days sounds impressively lazy, though anyone with actual fish will still want to trust the sensors, not the brochure. If this kind of product catches on, expect more pet-tech brands to lean harder into AI-assisted care rather than simple remote monitoring.
