I wonder if my fish would follow me around the house if they weren't confined to a tank 🤔

Some researchers created a tank on wheels, with cameras above it to track a fish. The cart holding the tank would move wherever the fish pointed. They trained the fish to swim toward a target outside the tank, then the cart would move, and the fish would get a reward.

For real. Look it up.

I've once had a super anxious dream in which they were floating around the room and I was panicking to close all the windows before they could escape and no longer be able to find the way back 😢

Imagine all of the things they'd eat. Your floors would be spotless
