They are also known for their ability to learn and adapt to new environments. In fact, they are known to be able to survive in the wild for up to a year without food.

Do goldfish get to know their owners?
Your pet goldfish may have hidden depths, beyond his glassy-eyed stare. Oxford university scientists have shown that fish can remember and recognise human faces. They are able to pick out a familiar face from up to a mile away.
The study, published in the Proceedings of the National Academy of Sciences (PNAS) journal, found that the fish were able to recognise the faces of their own species, as well as those of other fish species they had never seen before. The fish also performed better than chance at identifying unfamiliar faces, even when they were presented with a series of pictures of familiar faces and unfamiliar ones.
“We were surprised by how well they did,” said study co-author and fish behavioural ecologist Dr David Buss, from the University of Oxford’s Department of Zoology. “We expected them to do poorly, but they performed so well that we thought they must be doing it on purpose.” “It’s a bit of a surprise that they can do it, because they don’t have a lot of experience with humans.
How do fish see us?
Besides being able to see their prey and recognize their owners, fish also can see a range of colors, since they have color receptors in their eyes. Many species of fish can also see ultraviolet light, which humans can’t. Only humans have UV markings on their faces, which is why ambon damselfish have UV markings on their faces.
Fish also have a sense of smell that humans don’t have, and they can tell the difference between different types of food. For example, a fish that has been exposed to a certain type of algae will be more likely to eat it if it smells like that algae. Fish also know when they are in danger of being eaten by a predator, so they will swim away from the danger.

How do fish show affection?
Researchers have found that fish eavesdrop on each other. They show affection by rubbing against each other and remembering past social interactions with other fish. The fish’s ability to recognize one another is similar to that of humans, according to Dr. Michael J. Smith, a Biologist at the University of California, Santa Cruz. “It’s a very interesting finding,” he .
Do fish feel pain when they get hooked?
Fish have many nociceptors in their mouths and getting hooked is very painful for them. In addition to this, they also have a very strong sense of smell, which is why they are able to detect the presence of other fish in the water. They are also very good swimmers and can swim for long periods of time without getting tired.
