This $5,000 robotic fish looks like an arowana — and never needs feeding
A robotic arowana that swims, glides, and even shimmers like the real thing just launched in China — and it costs around $5,000. Chinese underwater robotics company FullDepth debuted the Bionic Arowana in March 2026, targeting aquarium hobbyists who want the prestige of a dragon fish without the extreme maintenance demands. No US or UK availability has been announced yet.
The fish itself
Real arowanas are notoriously difficult pets. They need tanks of at least 500–800 liters, precise water chemistry, and a diet of live or fresh seafood. They can easily cost $20,000 or more for a prized specimen, according to New Atlas. FullDepth's version sidesteps all of that.
The Bionic Arowana is 69 cm long, weighs 3.8 kg, and swims at up to 1.9 km/h (roughly 1.2 mph). It runs autonomously or accepts input from a wireless remote. The body is made from high-quality silicone with a metallic coating designed to replicate the iridescent shimmer of real arowana scales. Charging happens on an inductive platform — no cables — and a full charge lasts up to 12 hours.
The Bionic Arowana replicates the iridescent scales and fluid movement of a real dragon fish using high-grade silicone and an AI behavior model.
The realism comes from an AI-driven "neuro-drive" model that mimics the specific fin movements and gliding patterns of a live arowana. It's not looping a pre-set animation; the system generates naturalistic swimming behavior dynamically.
The claim vs. the reality
At $5,000, FullDepth is pitching this against the cost of a real arowana and its ongoing upkeep — not against a novelty toy. That framing makes some sense: a top-grade arowana plus a specialist tank setup can run well past $30,000 over several years. The robotic version needs no feeding, no water testing, and no vet visits.
Still, the price is unconfirmed — a company representative told ITSC News the $5,000 figure is planned but "yet to be finalized." And as of April 2026, the Bionic Arowana is only sold in China. FullDepth has not announced distributors, pricing in dollars or pounds, or a timeline for Western markets.
Worth watching
For now, the Bionic Arowana is a compelling curiosity with a high price and no clear path to US or UK shelves. If FullDepth does expand internationally, it will also need to navigate regulatory questions — the EU's AI Act enforcement begins August 2, 2026, which could affect how AI-driven consumer robotics are classified and sold in Europe. That's not a US concern today, but it signals the kind of friction any global launch will face.
