How long does a fish live?

Fish aquarium

You may have wondered how long does a fish live, what is its average life in an aquarium and the truth is that, for sure, I could not tell you an exact number of years because fish can live from a few hours to a few years, depending many times on the resistance of the fish, how old it is and also how it is raised.

When they have in fish tanks, not aquariums, the most professionals say they can last is 2-3 years because the fish do not hold much longer due to the stress that they live in it. Others say that, if they are well cared for, they can last for many years and accompany you in your life.

The truth is that the fish we buy are usually small in age (about 2 months old) with which they will last us at least a couple of years if we take good care of them. Also depending on the species, you will make it last longer or shorter. For example, the fish that are used to clean the windows, the cleaners, can last much more than 2 years if they are well and not stressed, in addition to growing a lot.

Experts say that fish, with good constitution and well cared for (discover how long can you go without eating), they can live 10-15 years in aquariums (not in fish tanks) and they can even extend that age longer, exceeding that of a dog. But, as I told you, it must be a very well cared for aquarium where it does not lack anything.

A "guiding rule»Tells us that the larger the average size of a species, the greater its longevity, so that the larger it is, the longer it will live, although you have to take this into account for your aquarium, you will not want a fish too much large because it can eat other fish.

How long do orange fish live?

Carp fish

Most of the fish that we buy in shops dedicated to the sale of pet animals are usually called orange fish, carp or goldfish. They are the most popular species and the one that we most frequently see in fish tanks and aquariums. However, they are not the oldest.

These fish are much more delicate and fragile than we think. That is why there are cases in which we buy one of these little animals and they survive for only a few months, and even a few days. It is true that this rule is not always fulfilled, since with the correct care, we can make the orange fish endure with us in 2 to 3 years.

It must be borne in mind that these fish are raised in large ponds where they develop and grow rapidly, despite being young. Therefore, all those specimens that are in the bird shops and pet stores are very young.

How long does a fish live out of water?

Fish out of water

One of the biggest concerns for breeders is how long the fish can stay alive out of the water. And, contrary to what we think, these animals can endure some time outside the aquatic environment depending on what the conditions are.

If, out of the water, the fish is in a place with rather cold room temperature and deposited on a surface that does not absorb moisture quickly, it can last with life up to almost 1 hour.

There are cases in which the fish have jumped, incredible as it may seem, from the fish tank or pond. If this happens, and we still find our fish alive, we must introduce it as quickly as possible in a container that has the same water as the fish tank or pond. Subsequently, we have to rinse it delicately with the help of a cup, in order to remove any possible dust particles, etc., that have adhered to its skin. It is very important that we bear in mind that we do not have to rub the fish with force to avoid causing external injuries. After observing it a few 24 hours Inside the container and having verified that it is okay, we will proceed to return it to the fish tank or pond.

How long does a fish live in the sea?

Within a marine ecosystem there are endless species, many of them fish. Among the different species of fish there are multiple differences, and the life expectancy was not going to be less.

Normally, fish that live in seas and oceans live longer than their companions that do the same in lakes and rivers. There are fish that barely live a year, while others live up to half a century. Exceptionally, sturgeons and groupers have been found with more than Age 100. But if we were to make an average of the life expectancy of marine fish, we would say that it is close to the 20 years..

If we want to know how old a fish is, there is a fairly reliable trick. As with the rings that draw the trunks of trees, if we look at the scales of a fish, they also draw a series of growth lines. Each of these lines reflects one year of age of the animal. To do this, it is necessary to use a high magnification magnifying glass, since with the naked eye it is almost impossible.

How long does a cold water fish live?

    I have an orange tent. I have it in the same container in which they gave it to me and the truth is that it is holding me a lot. The fish is 5 years old. This fish marks a stage in my life, I bought it when Hiba was in the first year of ESO and now that I am in a training cycle I realize what it is. If one of these days he goes away, a part of me goes with him. It is like a little brother, no matter how small they are, you love them like your relatives.

    My lebiasin or puddle fish lived up to 12 years and died as an old man, had practically hunched over and was blind in one eye, apart from its almost silver-green color having turned almost black and skinny on its stomach ... He was even interested in hunting smaller fish like the guppies that I always gave him for food ...
