Having the memory of a goldfish would actually be an upgrade for most other fish. Goldfish have been noted to remember things they are taught up to a year later, and will anticipate food if they are fed consistently at a certain time of day. Memory aside, goldfish are smarter than you may realize. Researchers have trained these fish to play fetch, push levers, do the limbo, and play a form of soccer. They can also recognize their owners, and can even pick a favorite (usually the one who feeds them). Goldfish have also exhibited signs of trust toward their masters, and will sometimes hide in the presence of strangers.
