Yes, fish can hear you talk! Sounds that are created above water typically do not carry enough force to penetrate the surface tension of the water, so talking on the boat or loud noise may not affect fish as much as your fellow anglers may want you to think. Your voice is unlikely to spook or scare fish away.
You may be surprised to learn that the answer to this question is actually yes! Goldfish can hear sounds even though they don't have ears!
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.
Noise which can disturb the natural behaviour of fish
Fish is extremely sensitive to low-frequency vibrations, below some 10s of Herz. If the sound source is sufficiently intense, fish usually respond by swimming away from the source.
Most fish, both in freshwater and salt, detect sound from 40 Hz up to 500 or 1,000 Hz (though some, like salmon, only hear to about 400 Hz, while others, such as herrings, can hear to over 3,000 Hz).
Not only can your aquarium fish hear you speak, but they can also respond to certain sounds, differentiate different types of music, and speak back to you through their body language.
With patience and a little persistence, you can teach him to do things like follow your finger, eat from your hand, swim through a hoop, play soccer, and even jump out of the water or come up to be petted. Fish food is the best reinforcement for desired behavior.
The same noise level in the air could lead to serious hearing damage over time. And fish have it even worse: since the sound pressure is four times higher under water than it is in the air, a good portion of deaths in public aquarium can be traced back to repeated tapping on the glass.
Like many fish, male Gulf corvina emit a thrum of seductive calls to attract females during breeding periods. But as Ben Guarino reports for the Washington Post, a new study has shown that the collective chorus of Gulf corvina is exceptionally loud—so loud, in fact, that it can damage the hearing of aquatic mammals.
While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.

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.
Groupers are not the only fish that enjoy being petted, it seems. According to videos on YouTube, other species of fish that appear to like the interaction include koi, cichlid and discus fish.
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.
Can your pet fish recognize your face? A new study says, Yes, it probably can. Researchers studying archerfish found the fish can tell a familiar human face from dozens of new faces with surprising accuracy. This is a big, big deal.
Fish quickly learn to associate you with food. When they see you, they'll come to the front of the tank and watch, anticipating that you're going to feed them.
The Batfish – Clowns of the Sea
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.
The number one spot is held by the mighty Monkfish. Also known as the Sea Devil, this Atlantic ocean deep water horror lurks at depths of 50 meters and deeper. They have a large broad head which is home to 100s of large, razor-sharp teeth which are used for ambushing prey.
Provide at least 24 square inches of water for every 1 inch of fish. The more room, the better! Fish become frustrated and unhappy when kept in cramped bowls or tanks. House fish in a large filtered tank.
“Glass surfing” is when a fish – such as betta fish, gouramis, and cichlids – repeatedly swims up and down along the tank walls. It could be caused by stress, boredom, defense of territory, and other reasons.
The answer is still no; as they live in water they probably don't take it in as a conscious response to seek out and drink water. Thirst is usually defined as a need or desire to drink water. It is unlikely that fish are responding to such a driving force. What about salmon?
Scientists have just observed a thought swimming through the brain of a live fish, and that thought concerned getting something good to eat. Fish and other wild animals appear to think a lot about food: how to obtain it and what to consume.
It is also possible that you are feeding them a little too much food. Fish only require a very small amount of food, so try feeding them a little less. Some fish also spit their food out if the particles are too big, breaking them down into smaller more manageable sizes.
