What is the ZURU Robo Fish?
Robo Alive Robo Fish Series 3 is a 2-pack robotic fish set (Teal + Orange in this case) that comes water-activated and ready to swim right out of the box. Made by ZURU, this is the third generation of the toy — and it brings smoother motion, brighter colors, and a neat color-changing trick.
Recommended for ages 3+, it’s perfect for bathtubs, kitchen sinks, or even makeshift aquariums.
How does Robo Fish work?
It couldn’t be simpler:
drop a fish into water — and it comes to life. With water-activated sensors, the motor kicks in automatically. Each fish swims in 5 directions, mimicking realistic movement.
Take it out of the water — it shuts off on its own. No switches, no charging, no fuss.
The color change feature that kids love
Series 3 introduces something extra cool — color-changing technology.
Once in water, the fish gradually changes its shade. The teal one in this set gets noticeably darker, which makes it feel like a whole new fish has just appeared. It’s subtle but satisfying.
Kids are mesmerized. Adults? Low-key impressed.
What’s new in Series 3?
- Fresh color combos: Teal + Orange, Red + Blue, Pink + Golden, and more
- Better motion tracking in water
- Improved body durability
- Comes with extra batteries included
Build quality and performance
These fish are small but solid. The plastic shell feels durable and smooth, not flimsy. The tail moves smoothly and doesn’t stick. We didn’t notice any drifting or stalling — and that’s impressive, especially when compared to knock-off robotic toys.
They actually swim — not just wiggle in place.
6 fish to collect in total
If your kid loves to collect, this set is part of a broader Series 3 lineup. There are six unique color combos total. If you already have previous Robo Fish or the Robo Aquarium, this adds variety and makes the “school” of fish more fun.
It’s also a subtle way to get kids interested in patterns, color recognition, and underwater play themes.
Bonus use case: prank your friends
These fish are so realistic that they actually make great prank props. One of our readers dropped one into a family aquarium — just to see what would happen. Cue confusion, laughter, and about 5 minutes of “Wait, is that thing real?”
Perfect for TikToks or casual “gotcha” moments at the pool.
Where to buy and how much?
As of now, the Teal + Orange 2-pack is available on Amazon for around $14.53. Other color variants are priced from about $12 and up. They come in clean, colorful packaging and include batteries — ready to go out of the box.
Final thoughts
The Robo Alive Robo Fish Series 3 set by ZURU is not just another bathtub toy — it’s a mini underwater experience. With real motion, color-changing bodies, and no setup required, they’re an easy win for parents and a hit with kids.
We recommend them for ages 3–10. But to be honest — everyone wanted to try them out.
