they have been reported to live as long as 30 years
(Lorenzoni et al. 2007).
How long can fish live up too?

.
Are there fish years?
Aging fish is similar to aging a tree by counting the number of growth rings. However,
the age of the fish is determined by counting the number of wide growth rings called annuli
. In our example, the bluegill is 4 years old.
Which animal lives the longest?
The
Greenland shark
has the longest known life span of all vertebrates, estimated to be between 300 and 500 years. Found in the North Atlantic and Arctic Oceans, the species can reach an astonishing 21 feet in length and mostly eats fish, but has been spotted hunting seals.
What pet fish live the shortest?
Killifish are among the aquarium fish with the shortest lifespan
. They generally only live for a bit more than two years. Bettas are not far behind.
What is the oldest fish?
Biologists at the California Academy of Sciences believe they host the world's oldest living aquarium fish in the world — and her name is Methuselah. Scientists believe that
Methuselah, an Australian lungfish
, is about 90 years old.
Can a goldfish survive in a bowl?
Some goldfish live happily in 3-5 gallon bowls their entire lives
, but ideally, an adult goldfish should be kept in a bowl that is at least 10 gallons. This will provide leeway with water changes when life gets busy and ensure the water quality is maintained.
Can you eat goldfish?
Goldfish are as edible as any other freshwater fish
. If you choose to eat it, know these facts first: That gross flake and/or pellet stuff is what your fish has been eating exclusively. Pop a pellet or two, that's what your fish will most likely taste like.
Do goldfish get lonely?
While we can never know for sure,

Do fishes sleep?
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.
How long does a shark live?
20 – 30 years
How old does a human live?
And even if we make it through life with few stressors, this incremental decline sets the maximum life span for humans at somewhere
between 120 and 150 years
.
Can fish love their owners?
Do Betta Fish Recognize Their Owners? 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.
Do fish get bored in a fish tank?
Fish-keepers sometimes see their pets ‘glass surfing' – swimming repeatedly up and down the glass of the tank. This could be the aquatic equivalent of the pacing of a captive tiger that's bored from a lack of stimulation. But
the fish could also be stressed from an overcrowded or unfamiliar tank.
Do fish like music?
If you've ever thought that your goldfish can't hear or won't respond to the music that you blast in your room, it's time to think again. Though few people know this,

Are dog years?
As a general guideline, though, the American Veterinary Medical Association breaks it down like this: 15 human years equals the first year of a medium-sized dog's life. Year two for a dog equals about nine years for a human. And after that,
each human year would be approximately five years for a dog
.
Do fish age the same as humans?
Gradually aging fish grow old similar to how humans do
– they take a few years to mature, reproduce for a while, and then stop reproducing for a few years before they die. Negligibly aging fish reproduce for their entire lifespan and are just as fit at the end of their life as early on.
Can you tell how old a fish is?
Biologists estimate fish age by counting these opaque zones, called annuli
, just as one would count rings on a tree to determine its age. For each species to which it is applied, the method of estimating age by counting annuli must be validated to prove that one whole annulus is equal to one year of growth.
Which animal lives for 500 years?
The
ocean quahog
is a fist-size clam that can live to be 500 years or older. Some researchers believe the sturdy quahog's secret to a long life is its ability to protect its proteins from damage.
Can turtles live up to 500 years?
As with whales, sharks, and other species, it is often difficult to determine a turtle's exact age. After all, researchers are not usually present when the animals are born.
Some have estimated, however, that large turtles may be able to live 400 to 500 years
!
What animal is immortal?
To date, there's only one species that has been called ‘biologically immortal': the
jellyfish Turritopsis dohrnii
