Yes, fish can hear people talking underwater because sound travels fast and efficiently through water, often five times faster than in air. While they lack external ears, fish detect sound vibrations using internal ears, swim bladders, and a lateral line system. However, low-frequency sounds travel best, and while they can hear noise, typical conversations may not scare them as much as abrupt, loud vibrations.
Fish don't have ears so they dont ``hear'' the way mammals do, but they sense vibration through their lateral lines. Essentially they ``feel'' the sound.
Fishes are approximately the same density as water, so sound passes right through their bodies, which move in concert with the traveling sound wave. Fishes have structures in the inner ear, called otoliths, which are much denser than water and a fish's body.
A number of studies have shown that fish can retain information for months or years. Anecdotally, channel catfish (Ictalurus punctatus) can remember the human voice call announcing food five years after last hearing that call.
Constant noise becomes part of the environment and less distracting to the fish. This even applies to people talking: divers can hear a conversation above water, so it is safe to assume that fish can too.

Can fish feel you talking?
Talking produces vibrations that travel through the air and can enter the water. Loud talking or shouting creates stronger vibrations, which fish can detect. These can also be transmitted through the hull of a boat – or the ground if you're shore fishing.
In 2009 the myth that a fish have a memory span of 3 seconds was proven wrong, and it is now believed that their memory can last up to 5 months. Survival skills, especially when housed with aggressive tank mates, are repeated and often continuous signs of stress remain long after 3 seconds have elapsed.
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.
According to tank scapping, most fish recognise their owners or more precisely their feeders. Particularly those that swim higher in the water column quickly learn when feeding time is and who feeds them. But some species can truly recognise human faces.
Fish — and goldfish, especially — may be described as having a short attention span, but the study seems to prove that they're capable of responding to sounds in meaningful ways.
They can and will see you if you do not take care in your approach and your presentations to them. Once you're spotted and one fish spooks, they will send alarm bells to all the rest of the fish in the spot and your chances of catching a spooked fish are zero.
The chemical composition of DEET, one of the world's most effective fish-repelling substances; if you want to scare off some fish, this stuff is just the ticket.
When many fish nest in one area, they can produce a loud chorus of hums. After the discovery, the town, once perplexed and annoyed by the midshipman's mating calls, started the Sausalito Humming Toadfish Festival to celebrate their local singing fish. The Plainfin Midshipman is not alone in its singing ability.
So to answer the question if fish love and can show their love to their keepers, the answer is yes! Just like other pets, fish show their love and appreciation when they are happy. Unhealthy and poor water condition can make them feel sick and very unhappy.
Elephants are considered to be one of the world's most empathic species as this is displayed throughour their interactions. In the wild, Asian and African elephant calves rely heavily on their mothers and family members for survival, social support, and learning during their first four to five years of life.
In May, 27 percent of hook wounds were healed within six days, but only 12 percent were healed within six days during July. No differences in hook-wound detection or healing rates were found for bass caught on crankbaits versus plastic worms.
a recent study shows that fish can suffer for up to an hour after being pulled from the water, experiencing pain and fear much like humans do 🤕 they have pain receptors, produce natural painkillers, and show clear signs of distress fish don't scream, but their suffering is real please leave fish off your forks 🐟
Fish Have Feelings, Too: The Inner Lives Of Our 'Underwater Cousins' But Soares and Maximino wondered whether fish could feel good, too. In a study published in the journal Proceedings of the Royal Society B, they and their colleagues conclude that fish can feel pleasure and that they actively seek it out.
The British Farm Animal Welfare Committee 2014's report, Opinion on the Welfare of Farmed Fish, said that the scientific consensus is that fish can detect and respond to noxious stimuli, and experience pain.
You may notice that when you come into the room where your aquarium is, the fish start to react by swimming around and coming up to the glass or the surface. This is because they recognize that you are the person who brings them food.
Fish are believed to absorb negative energy, keeping the environment peaceful. Flowing water symbolizes wealth and uninterrupted cash flow. It is known to reduce stress and anxiety due to its calming visual effects. The movement of healthy, active fish is said to ward off ill-health and bad omens.
