( January 4, 2022; *Ars Technica* ) **_Description_**: "The fish learned to operate a fish tank on wheels."

[![](https://cdn.arstechnica.net/wp-content/uploads/2022/01/goldfish-dreaming-of-driving-760x380.jpg)](https://arstechnica.com/science/2022/01/goldfish-can-learn-to-drive-and-navigate-terrestrial-environments/)

Six fish took part in the experiment and were taught to drive in 30-minute sessions, conducted three times a week, every two days. To begin with, the fish were given a reward if they navigated to a target (a pink corrugated board) from the center of the enclosure. The fish did indeed learn to drive the FOV, becoming more proficient in its operation over time both in terms of achieving tasks (navigating to a target) and in the time taken to complete that task. The authors wanted to check that the fish weren't just memorizing a set of movements to earn a reward, so they repeated some tests with a new starting position inside the enclosure or added decoy targets that were a different color.

---- The study, [From fish out of water to new insights on navigation mechanisms in animals](https://www.sciencedirect.com/science/article/abs/pii/S0166432821005994?dgcid=author#fig0005), was published in the Februray, 2022 issue of [Behavioural Brain Research](https://www.sciencedirect.com/journal/behavioural-brain-research). The findings suggest that the fish maintain an internal map of the external world, including the terrestrial world outside of their enclosure. I couldn't find any videos of the current research, but here is a 2019 video of a previous initiative with a goldfish driving its own fish tank.
