FullDepth presents Bionic Arowana, the robot fish that needs no aquarium

Published on April 29, 2026 | Translated from Spanish

FullDepth, a Chinese robotics company, has launched the Bionic Arowana, a 69 cm robotic fish that mimics the movements of the expensive arowana fish. Weighing 3.8 kg and reaching a speed of 1.9 km/h, this alternative aims to offer the visual pleasure of owning an arowana without the high maintenance costs or intensive care required by the living animal.

Lithium battery and remote control for navigating up to 20 meters 🐟

The Bionic Arowana runs on a lithium battery providing up to 12 hours of autonomy. In addition to swimming autonomously, it can be controlled remotely, although its range is limited to shallow waters. The robot can dive up to 20 meters, allowing for some underwater exploration. Its design replicates the swimming mechanics of a real arowana, using articulated fins to move fluidly.

For those who want a fish without the drama of dirty water 😅

If you always dreamed of having an arowana but were put off by cleaning the aquarium every week, FullDepth has the solution. This robotic fish doesn't eat, doesn't poop, and doesn't get stressed if you forget to change the filter. Sure, it won't look at you with pleading eyes when you approach, but in return, you won't have to explain to your guests why your 500-euro fish is floating belly up. Just make sure you don't lose the remote control, because chasing a 69 cm robotic fish around the lake isn't as dignified as it sounds.
