While their memory isn't as long as a human's, goldfish can remember things for months, and possibly even years.
Research has shown that they can:
* Recognize their owners: Goldfish have been shown to recognize their owners and respond to their presence.
* Learn mazes: They can be trained to navigate simple mazes and remember the correct route.
* Remember feeding times: They can learn to associate specific times with feeding and anticipate when their next meal is coming.
So, while they might not remember everything, goldfish have a surprisingly good memory for a small fish!
