A wee-brained tropical fish can distinguish between human faces in a lineup, researchers have found. This is the first time such an ability has been shown in fish. Recognizing human faces is a difficult task.
Surprisingly, science has found that fish are capable of recognizing their owner's face, even if the owner is standing by the tank with other people. Fish can develop an association between something they like, being fed, with the person who feeds them.

"It is a basic characteristic of animal behavior that animals will approach desirable things and retreat from undesirable ones," he said, adding that the fish "appears to like the touch because s/he swims back to the hand repeatedly."
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. In fact, ambon damselfish have UV markings on their faces, which only they can see.
However, yes, they can hear your voice.
They just know someone is speaking. They can associate sounds with action, though. For example, if you are to say your betta fish's name – let us call him George – each time you sprinkle food in his aquarium, he will eventually associate the sound of “George” with food.
Researchers have found that fish recognize each other and gather information by eavesdropping. They're capable of remembering past social interactions that they've had with other fish, and they show affection by rubbing against each other. Dr.
To stimulate your fish's brain, give it toys like floating rocks and caves for it to hide in. You can even train your fish to do tricks like swim through a hoop or jump out of the water with a little practice. Keeping your fish healthy and active will help you enjoy your fish for longer.
For fish, that title goes to manta rays. They're giant, charismatic and basically geniuses. Mantas have huge brains — the biggest of any fish — with especially developed areas for learning, problem solving and communicating.
Goldfish are certainly smarter than you think. Some have been observed to perceive and remember well enough to distinguish between people. They often notice the person who feeds them each day, and will get excited when they see them.
But, can fish understand human language? Sadly, no. There has been no evidence to prove that fish can remotely decipher the human language. They may recognize human faces and actions but not understand a word of what is being verbally told.
“Fish are more intelligent than they appear. In many areas, such as memory, their cognitive powers match or exceed those of 'higher' vertebrates including non-human primates.” Fish's long-term memories help them keep track of complex social relationships.
Fish become frustrated and unhappy when kept in cramped bowls or tanks. House fish in a large filtered tank. All tanks should have a pump to keep water flowing continuously.
Because fish often rely upon a complex web of senses beyond sight, many signals - chemical, hormonal, activity and sound - will attracts them and they know when you are, and will trail you, long before you see them.
If your fish is swimming frantically without going anywhere, crashing at the bottom of his tank, rubbing himself on gravel or rocks, or locking his fins at his side, he may be experiencing significant stress.

Fish are attracted to certain sounds and vibrations and not to others. Certain types of music and sounds repel fish while others interest them. Music and other sounds can define the change in the way fish behave in the water, including their eating and swimming patterns.
Do not reward your fish until it follows your finger. Use repetition and rewards to train your fish quickly. The fastest and most effective way to train your fish is by using food to reward its behavior. With repetition, your fish will learn to associate following your finger with being fed.
What they found was that both the female and the male she had chosen were slower to spawn and became a little more glum. This shows us that fish do feel companionship and that it's not just humans or mammals, so love really is in the water!
After this experimentation, scientists concluded that fish are able to recognize their owners. They can also develop a bond with their owners. Of course, not like other pet animals, but in their own way, they do love their owners, and this is quite amazing.
Have you ever wondered to yourself “What is the friendliest fish in the ocean?” Well, wonder no more! The answer to this question is actually quite obvious, it's the ever so curious batfish.
