With proper care, fish can live for three to five years. Some breeds live a decade or more. The common goldfish, one of the most popular pet fish breeds, can grow to be up to eight inches long and can weigh more than 1,000 pounds.

Can fish live for 100 years?
The coelacanth — a giant weird fish still around from dinosaur times — can live for 100 years, a new study found. These slow- moving, people-sized fish of the deep are not what you would expect from a fossil record. “Living fossils are rare, but they’re not unheard of.
Photos of a Living Fossil Fish] “It’s a very unusual fossil,” said study co-author David Evans, curator of invertebrate paleontology at the museum. “This is the first time we’ve found a fossil of this size and age, and we don’t know how long it has been alive.
What is the longest life of a fish?
According to the washington department of fish and wildlife, rougheye rockfish have a maximum lifespan of 205 years. The pink or brownish fish live in the Pacific Ocean from southern California to northern Baja California, Mexico.
Roughly the size of a small dog, the rough-skinned fish can grow up to 10 feet long and weigh as much as 1,000 pounds. They are known for their sharp teeth, which they use to pierce the flesh of their prey.
These fish are also known to eat other fish, such as anchovies, sardines, mackerel, and herring.
Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. According to research, fish may be less active and less alert to danger. Some fish float in place, others wedge themselves into a secure spot in the mud or coral, and some simply rest on the surface of the water.
Some fish, such as the Pacific bluefin tuna (Thunnus thynnus) and the Atlantic cod (Gadus morhua), are known for their ability to stay awake for long periods of time. These fish have been known to sleep for up to 24 hours at a time, which is longer than any other animal on Earth, including humans.
Do fish need to eat every day?
Feeding your fish once or twice a day is sufficient for most. Some people fast their fish one or two days a week to make sure they don’t get sick. Smaller, more active fish can go longer between meals than larger, more sedentary fish.
If you have a fish that is very active, you may need to feed it more often. If you are feeding a large fish, it may be necessary to increase the amount of food you give it. You may also want to consider feeding the fish more frequently than once every two to three days.
Do human fish exist?
The olm, a foot-long salamander nicknamed “the human fish” because of its fleshy skin and tubular shape, is certainly a strange-looking animal. Olms can live for 100 years, which is far longer than any other amphibian. Scientists don’t know why they live so long, but they suspect it has something to do with the fact that their skin is made of the same molecule found in human fingernails and toenails.
Olms have been around for a long time. They were first described in the 18th century by the French naturalist Jean-Baptiste Léopold Trouvelot, who described them as “a kind of fish with a human face.” The name stuck, and the species has since been found all over the world, including the United States, Europe, Australia, South America, Africa, Asia and Australia.
How old is the human fish?
Fish is on NPR. One of the most important human ancestors was an ancient fish. Though it lived 375 million years ago, this fish called Tiktaalik had shoulders, elbows, legs, wrists, a neck and many other basic parts that eventually became part of the modern human body. It was a fish, but it was also a human.
This is the story of how that happened, and what it means for the future of our species. The science of human evolution is a fascinating story. But it’s also one that’s been told many times before. In this episode, we’ll tell you how it all started.
You’ll learn about the origins of language, the evolution of sexual reproduction and the role of genes in human development. And you’ll hear from scientists who have spent their careers trying to figure out what’s really going on in our bodies and brains.
How long do fish sleep for?
They prefer to sleep in the night. They require an average of 8-12 hours of sleep every day to keep their functions active. Some species are nocturnal while others are more active during the day. They are omnivorous and eat a wide variety of plants, insects, fruits, seeds, and other small animals.
Their diet consists mainly of small mammals; (Check list below)
