If you constantly find yourself flushing goldfish down the toilet, these robotic pet fish by Hexbot are a better investment. These robots are especially perfect if you constantly forget to feed your fish, or are away on vacation a lot.
When an 'Aquabot' is dropped into water, it automatically turns on and begins to swim like a real fish. The movements of the fish are incredibly realistic and the thin material that makes up the fins and tail on the fish add to the illusion. To conserve its battery, the fish only swims for about five minute intervals at a time before resting.
Hexbot's robotic fish come in shark and clownfish shapes, with varying levels of transparency so that you can see the mechanisms inside.
