The most beautiful fish in the world. In the process of domestication of wildlife many centuries ago, freshwater inhabitants were also involved.

The first mention of artificial farming fish dates back to 1500 BC. C. It all started in China, it was here that ornamental fish were taken to keep them in small outdoor pools or aquariums.

Over time, the meticulous work of scientists and amateur aquarists in breeding and hybridization led to the emergence of new breeds of ornamental fish. In all this variety, it is difficult to choose the brightest and most attractive, but we will try, and we have the most beautiful. aquarium fish .


Burton’s Astatotilapia (Astatotilapia burtoni)

The most beautiful fish in the world

Agile and agile fish will add joy and optimism to your aquarium. In science, Danio is a model organism in which many biological processes are studied.

Betta fish (Betta splendens)

A small, agile fish from the macropod family is also called a Siamese rooster.

Due to the complex organ, it can breathe atmospheric air, so aeration of aquariums is hardly required.

Due to the aggressive nature of males, which were used in tournament fights, ornamental fish got their main name.

Pelmatochromis – Parrot (Pelmatochromis Kribensis)

This type of fish received its nickname for its color and similarity to parrots.

At present, 7 species of these the most beautiful fish in the world are known from the cichlid family. The color is bright with a violet violet tint. During the spawning period, females show a peculiar blush.

Veiltail (Carassius gibelio forma auratus)

An artificially bred fish is considered one of the most beautiful aquarium fish breeds . The goldfish queen has elongated fins and a stunning, veiled tail.

In the United States, this species of fish was brought from the Mikado Gardens in Japan. In difficult conditions, it was possible to preserve the original breed, and now the price of these fish is very high, and unique specimens are sold by individual order.

Guppy (Poecilia reticulata)

Another very popular and well known fish in the aquarium community.

In 1886, scientist Robert Guppy spoke to the Royal Society about a small viviparous fish. So these minnows got the name of the owl from the scientist’s name.

Surprisingly, little guppies are the first aquarium inhabitants to go into space.

Pearl Gourami (Trichogaster leerii)

The silver body of this labyrinth fish is adorned with evenly distributed specks of mother of pearl.

With the help of an original organ called a “labyrinth”, they can breathe atmospheric air. Without reaching the surface of the water for a long time, the gourami die.

A very peaceful and very shy fish appeared among Russian aquarium lovers in 1947 and is now one of the most popular decorative breeds.

Disco is common name for inhabitants of the Amazon basin of the genus Symphysodon.

These ornamental species have a rounded, flattened body with nine dark vertical stripes on a silver background.

The first representatives of this genus of ornamental fish were brought to Europe after the First World War. The discs are very demanding with their content. Large aquariums and weekly water changes are required.

Scalaria (Pterophyllum)

The Latin name for the most beautiful fish in the world comes from two Greek words “wing” and “leaf”. In fact, the original body shape looks like these two objects.

Chromis butterfly (Microgeophagus ramirezi)

This agile little fish has a small crown-shaped fin on its head and truly royal color.

The body of the “butterfly” is yellow with a brilliant bluish sheen. The throat and chest of the beauty are golden. The fins, in an original shape, are transparent with a red border.

Unlike the male, the females have a pink or crimson abdomen. Also, the male is slightly larger and has an elongated radial dorsal fin.

Sumatran barbus (Barbus tetrazona)

The schools are constantly on the move and are therefore true activators of the water.

In mobile aquarium inhabitants, the original color is black stripes on a silver body and the fins have a red border.

They can stick to other fish, but living in a flock, the barbusses are busy with each other and leave other residents of the reservoir alone.

Cichlasoma severum (Cichlasoma severum)

This fish is found in all bodies of fresh water in the north. South America … In the scientific world, it received a new Latin name Heros severus.

The pink and brown spots create a strange pattern on the fish’s body. The cichlazoma itself has a different color : from light yellow and greenish to dark brown.

Peace-loving fish show aggression only during the spawning period and while caring for the offspring.

The bottom of the aquarium must be free of vegetation and decorative elements so that the tracks can move freely.

This is a bottom fish, therefore this characteristic must be taken into account when feeding. The food for the parsnip should sink and then the fish can easily pick it up from the bottom.


Goldfish are the most popular with freshwater aquarium enthusiasts.

These beauties have various body and fin shapes , as well as variable color.

Breeding work has transformed fish and today all kinds of fish can be found in all parts of the world.

A beautiful inhabitant of aquariums also requires special care, that is, constant aeration and frequent water change . Goldfish overfeeding should be avoided.


Now aquariums can be found not only in homes, but also in offices, businesses, hospitals, and kindergartens. Doctors recommend putting them in staff bathrooms. It has become popular in zoos to equip exotariums, where the ecosystems of the seas, rivers and oceans are reproduced, where exotic fish species are kept.

But, like any living organism, aquarium fish require special care and certain conditions of detention. The aquarium, in fact, has become a separate science to recreate an ecosystem in a confined space.

Aquarium fish are whimsical pets, but at the same time beautiful. Some people can literally sit for days, watching these incredible aquatic inhabitants … However, this is not at all surprising, at first glance it is the most beautiful, colorful and bright fish that attracts the attention of not only children, but also of most adults.

Aquarium fish are whimsical pets, but at the same time wonderful

First of all, fish are usually treated differently than, for example, dogs or cats. This is not surprising, because a person has the ability to contact these animals exclusively visually. However, when starting an aquarium, you need to take into account the fact that there will be the same living creatures.

  • The aquarium itself is impossible without its inhabitants: beautiful aquarium fish inhabit it. Although they are the main point of any aquarium, it is still necessary to add plants there.
  • Fish diseases are treated with a little more difficulty than diseases of cats and dogs.
  • The larger the volume of the aquarium chosen, the longer it will take to clean it completely. However, fish need relatively less care.

However, if you decide to have aquarium fish, then the most important step in this process is the selection of the aquarium. It is worth considering the main points when choosing an aquarium:

  • the larger the aquarium, the less routine maintenance it requires, but the longer it takes to fully clean it, which should be done at least once a month. Fish are the same living things, you must clean them in the same way, and you must also refresh the water by adding clean water to the aquarium. The larger the container, the less noticeable contamination of the aquarium will be, but it will take several hours to clean all its corners, and you should be ready for this;
  • First decide what type of fish and how much you would like to see in your aquarium, as there is a risk of buying a less boat than necessary. The size of the aquarium must be 100% suitable for the number of fish, otherwise you will clearly not become a successful aquarist. You will learn which fish is best not to contain in the next paragraph;
  • pay attention to your aquarium’s exterior design . Contrary to popular belief, it is not only necessary for general beauty. For some species of fish, it is simply necessary to have a variety of decorations, stones, plants in the aquarium. This is especially true for various catfish. It is a good idea to consider all factors before purchasing an aquarium. It is necessary to take into account the preferences of all types of fish and plan in advance the landscape that suits them. Having planned this in advance, it will be easier for you to determine the shape and volume of the aquarium;
  • a real highlight of the interior of an apartment or house can be an aquarium of any avant-garde or extraordinary shape. It will really look great from the outside, but when shopping for a live fish container, be prepared for the fact that all possible discomfort during cleaning will increase by about 3-5 times. A rectangular aquarium is a good classic, and if you need a medium or large volume, then you should go for this one. There are many varieties for small decorative aquariums, but with a small volume they do not play an important role.

Important points when buying an aquarium

There are many factors to consider when purchasing an aquarium. It will be advisable to immediately buy him a lid with built-in lighting, because this factor is extremely important in an aquarium. There are many different formulas by which the amount of light required is calculated, but this already depends on the plants you choose and, of course, the type of fish that will live in this same container. For example, bottom aquarium fish, as a rule, require much less light.

Another very interesting question that a novice aquarist may face is whether to choose the material for the container: glass or plastic. Of course, this choice is purely subjective and depends solely on the quality of this or that material. However, plastic has far more unpleasant disadvantages than glass. For example, some manufacturers are known to use glue when gluing a plastic aquarium, which is toxic to aquarium fish. The same problem is seen in the glass variants, but it is much less common. And if the family has young children, animals like cats and dogs can easily scratch the plastic.

Of course, in the age of technology, everyone knows that it can be polished. However, later a short time after polishing, the plastic will be covered with a lot of small scratches, making it difficult to see living things, making everything look cloudy and ugly. And one day it will be so cloudy that you will no longer see your own fish.

Glass is good for everyone. If anyone still thinks that a glass aquarium is easy to break, then this is absurd. They are literally eternal; it is difficult even for an adult to leave a scratch on the glass. However, not all sealants are suitable for joining glass aquariums and some are also toxic.

There are also frame aquariums. To be honest, they are the real “monsters” in the world of fishing boats. The frame is assembled with metal and the joints are sealed with resin, which is harmless to fish. A large capacity aquarium filled inside and with water weighs a lot, so you should think in advance where it will be located.

Fish information

It is impossible to list absolutely all types of fish; Furthermore, scientists are constantly breeding new species by crossing one fish with another. It is curious that a person who does not know it often classifies aquarium animals into yellow, red, blue, beautiful and ugly aquarium fish. Also, its size rating is popular.

Exotic fish need special care, they need a certain salinity of water, a certain light, certain nearby plants. For a beginner, all this is difficult and incomprehensible, in addition, for most experienced people these things also cause difficulties. Fish farming experience comes over the years.

The most popular aquarium fish are:

  • guppy.Yes, it is the most popular and well-known aquarium fish. Caring for her is really extremely simple, it’s unpretentious. Nor will there be problems in breeding, since it reproduces if you keep males and females in the same aquarium. Guppy is a viviparous fish, at a time it can produce from 10 to 50 fry. It is advisable to plant them immediately in another aquarium, since in general they run the risk of becoming food for large fish. Male guppies have a beautiful shiny tail, while female guppies are inconspicuous and gray. The only drawback of this fish is that although it belongs to the category of “most popular aquarium fish” and even tops it, the guppy is a very stupid fish, it is not liked by many connoisseurs precisely because of this. There is one more: Endler’s guppy. These fish are smaller, they reproduce more frequently. In food, all guppies are unpretentious;
  • swordtails. These fish are nicknamed this because the males have a very elongated anal fin and it really looks like a small sword. Females have no such feature. Swordsmen are often valued for their pure color, whether it is pure red or pure black, so these species should not be mixed, and differently colored males and females should not be kept together. Swordsmen are much larger than guppies, but they are unpretentious when it comes to food and lighting. They are equally easy to breed. Don’t fill the aquarium with a large number of male swordtails, they are quite aggressive fish;
  • zebrafish. Small, small fish sight , characterized by a black stripe of color. There are already more nuances in zebrafish content than there are in guppies or swordtails. First of all, it is a growing fish, that is, you must keep at least 5-6 individuals in an aquarium. Also, this striped fish can safely jump out of the aquarium, as it is very mobile, has a lot of energy. Danios are not viviparous, they lay eggs, so the reproduction process is a bit more complicated. It is interesting that they eat absolutely any type of food, but the best option for these fish – dry flakes;
  • barbs. As a rule, bright and the most beautiful fish in the world , they can be bright red, each type of barbus is good in its own way. They are omnivores, they do not require special care. However, for these fish, it is necessary to select the environment well, as they can be quite conflictive.

Now it is worth knowing such a subspecies as bottom aquarium fish. Catfish not only decorate the environment, but also help the owner to keep the aquarium clean and tidy.

The most popular catfish

As a rule, these fish receive little undeserved attention. However, catfish help create a favorable fish fauna.

Catfish breeds:

  • ancistrus. They are great aquarium inhabitants. They can grow up to 13-15 cm if the size of the aquarium allows it. Also, they gained popularity due to their funny appearance – a black body with small white dots. This catfish is not easy: it eats plants, but at the same time cleans the walls of the aquarium along with decorative elements. Like all catfish, it should be fed special herbal tablets that do not remain on the surface of the aquarium, but immediately go to the bottom. It is there that the catfish collect them;
  • hallways. These catfish are much smaller. These fish are very interesting to observe when they are in a flock, so it is necessary to start several individuals at the same time. They are also very mobile and at the same time small, collecting the remains of food that have remained at the bottom, they clean the aquarium. They can be kept together with ancistrus, because these fish are fed according to the same principle, only with special tablets.

As you can see, the practical benefits of this type of fish are significant. However, it is always worth remembering that an aquarium is a small ecosystem but still.

Aquarium pets are not for beginners

Very often, people, carried away by the appearance of a particular fish, immediately drag it into their aquarium, and then are also outraged that it has not taken root. This is fundamentally wrong.

The names of the fish species that failed the most in the first experiment:

  • roosters. They can be found in any market, they are very colorful and very pretty, they can have an iridescent red or blue tail. In addition, they eat almost everything that is horrible, but it was not for nothing that this fish was given that name. Roosters are very conflictive fish, one of the most conflictive fish in general. By the way, they are so in conflict that it is better to keep them alone. Even then, there is a risk of the rooster jumping out of the tank (if it doesn’t have a lid). If you put the rooster with other fish, they run the risk of losing their fins and being seriously injured. The coloring, however, pleases: blue, red, orange;
  • the above characteristics are totally consistent African cichlids should take the same care with them;
  • crystal catfish. A fish that will definitely surprise everyone with its appearance. It is almost completely transparent. However, it is very sensitive to any changes in the aquarium. The aquarium is a subtle science, and the experience of having such wayward fish comes with time, and these are definitely not the best animals for the first try.

Fish are difficult to keep

These fish are difficult to keep due to their size and general requirements:

  • koi. People often see this fish in decorative ponds. In an aquarium of course it can also be kept, but koi are similar in size, even typical of the carp family, that is, you can keep them in an aquarium, but not for long. They grow quickly and take up a lot of space;
