Aquarium types and sizes

Aquariums are of two kinds and of several types and many sizes. The first kind is a freshwater aquarium for keeping and breeding fish that live in freshwater reservoirs of different countries of the world, as well as aquatic and underwater plants and other life forms that accompany them. The second kind is a Marine Aquarium that contains marine life of fish, plants, corals, and others.

Marine fish aquariums are difficult to maintain, and precisely because it is difficult to maintain an aquatic habitat for fish (and this is not limited to salinity). Marine fish are usually more sensitive to changes in their environment, as these parameters are not usually changed much in open water.

Aquarium kinds

Under the term freshwater aquarium, there are two main types. The first type is the aquarium community. As the name suggests, it consists of several fish species that exist together quite harmoniously. The aquarium community is especially popular with beginners. In most cases, communities of unrelated species are maintained when the water demand is not very strict and the behavior does not threaten the community as a whole. Other communities include species that originate from a single place. For example, the African lakes.

The second type I would like to introduce to you is an aquarium of a kind of fish. Such aquariums are kept when the habits of the inhabitants do not allow a neighborhood, but this does not mean that one type of fish is kept only because they do not get along with other species. Some experienced fishkeepers hold a species specifically and breed it.

Aquarium types and sizes

The community decorative aquarium. This aquarium is primarily intended for the decoration of the interior, as well as for monitoring the development and behavior of fish and plants. There are many fish species of different systematic groups and geographical zones peacefully coexisting in it. It is recommended to choose the size of the aquarium from the possibility of good gas exchange, i.e. the ratio of the water surface-i.e. the length and width to the square of the height of the water column should be about 2.5 or more. In such an aquarium, fish and plants are selected regardless of origin and habitat, and the main parameter here is a purely aesthetic perception.

Geographic aquarium.

Fish and plants from the same region are placed in such an aquarium.


This aquarium reproduces a section of the underwater landscape (stream, river bank, Rocky Lake Shore, etc.).), each area, and selects fish and plants from the same area.

Species aquarium.

This aquarium is characterized by the presence of fish of one species, genus, or several similar fish species and serves to observe their relationship to each other, behaviors, and reproduction. For successful breeding, it is sometimes necessary to have in this aquarium stimulating fish from another genus that forces parents to show their qualities: to protect the eggs and offspring.

The Dutch aquarium type.

The basis of its arrangement are aquatic plants, and living inhabitants (fish, mussels) play a secondary role and serve mainly to enliven the composition. Different shapes, sizes, colors of these types of plants allow you to create interesting and diverse compositions that give the interior originality and uniqueness. Most often, individual bushes are collected in dense groups, so that when viewed from above, only their tips are visible. Plants are planted in such a way that the plants in the foreground do not cover the plants growing behind them. The selected species should not form floating or above water leaves. A design feature of the Dutch aquarium is the difference in its geometric dimensions to the size of a conventional aquarium.

The peculiarity is that the width of the plant aquarium is much higher than its height, which allows you to create something like a mini pool or a home lake with transparent walls. The length of the Dutch aquarium is usually significant (at least 1-2 meters) and the volume exceeds 200 liters. For normal growth and life of plants, the Dutch aquarium must be equipped with a light source that must provide the right light regime. Lamps should be placed every 10-15 cm along the entire length of the aquarium. An additional effect is created by directed light sources in the form of light bulbs, which distinguish a single plant or a small group from the total mass.

Decorative outdoor aquarium.

This aquarium, in which there is no cover glass and no top cover, lighting equipment is suspended at a sufficient distance from the water surface, which allows plants to grow above the water surface and some of them to flower above the water.

Pseudo-Marine Aquarium.

For beginners, mastering the wisdom of marine aquariums is associated with certain difficulties and very considerable material costs. It is a very different thing when the whole design style is designed in the marine spirit, but the water in it is fresh and the inhabitants are freshwater. Many people follow the easiest way-decorate a typical freshwater aquarium with corals or shells of exotic shapes and colors from the warm Coast. But this option is not the best because mixing diametrically opposite styles does not have a positive effect.

To fill the floor, use natural marble shavings, synthetic painted floors. There are no restrictions on the size of the soil, as there will be no live plants in our aquarium. Despite the fact that the aquarium is bright and high — contrast, it is not recommended to use artificial floors of unnatural colors-blue, green, red. Natural materials are used for decoration, including dead corals, stones of porous limestone. Water in an aquarium with such materials will inevitably be hard, and residents should be selected based on this feature.

The choice of lamps in the aquarium pseudo-is determined not only by the needs of plants and decorative purposes. Cold-colored fluorescent lamps are better suited here. An interesting effect is achieved by the use of halogen lamps: due to the fact that their strong directional light forms distinct shadows of Fish and decorations on the bottom of the aquarium, the reservoir becomes more visible relief and dynamics.

The “kings” of the pseudo-sea aquarium-cichlids from the African lakes of Malawi, Tanganyika, Victoria-are not much brighter than the inhabitants of the coral reef. Preference should be given to species that like hard water: Pseudotropheus, Lamprologus, Haplochromis, and other Malawians, Victorians, as well as Xiphophorus, common molly, and other representatives of the Livebearers. Its bright color contrasts perfectly with Gray Coral, bright background.

If the color of the fish is not enough to form a bright image, the lack of Colors is compensated by more colorful decorations. You can keep pseudo marine aquarium melanotaenia Atherinidae. If you use only synthetic decorations that may contain the pseudo marine aquarium type then some large cichlids, such as hybrid parrots or Red Parrot Cichlid, a fairly bright and unpretentious.

Saltwater aquarium.

Brackish water aquariums are those with a specific water weight in the range of 1.005 to 1.015 (salinity according to specific weight). Simply put, the lower limit is near freshwater and the upper limit is near seawater. There are some species of animals and plants that live in a special (water salinity no more than 1-2%) environment that is not often found in nature. These are species such as Cottonwood (Chara fragilis), Cryptocoryne ciliata, brackish water diatoms. Tail stingrays, many species of viviparous fish (for example, guppies, some common molly) are found not only in fresh but also in brackish water. The choice of fish species should be extremely carefully considered. Although the total number of species in any type and size of aquarium that can be kept in brackish water, is much smaller than the number of freshwater and marine systems, there are still enough of them to make an interesting collection.


Represents a continental section of life. This is an artificial aquarium type in our usual life or in a special interior. Glass walls are a prerequisite for an aquarium, requirements for a terrarium are somewhat freer: part of the enclosing surfaces can be made of other materials, such as asbestos cement, lined with stones, and for many animals glass can replace a grid. The terrarium can contain a variety of vertebrates as well as invertebrates such as spiders, ants, termites, scorpions, insects, etc. The terrarium must guarantee that it is impossible to leave its place.

It is not recommended to keep fast-breeding pets at home, especially insects. This is usually the American cockroach (Pepiplaneta orientalis), the common cockroach (Blatta orientalis), or other colored representatives of cockroaches. Small larvae are so mobile and ubiquitous, that it is difficult to keep everyone in the terrarium. Of the most spectacular exotic invertebrates, many contain scorpions or large spiders that have lived in captivity for many years. Mostly terrariums contain small vertebrates. They contain various rodents (rats, mice, small sand representatives, toads, snakes, lizards). Their representatives need a dry, warm volume that reproduces the living conditions in deserts, semi-deserts, savannahs, and steppes, or a moist terrarium of rainforest and swamps.

The composition of a terrarium depends largely on pets, their habits, and their needs, their diet. In addition to food, it is necessary to offer various accommodations. Many of them require infrared heating. Sometimes it is possible to plant various unpretentious plants, preferably hard-leaved. These are representatives of bromeliads, lianas, ferns, and other plants that can get along with their pets.


In the terrarium and aquaterrarium, the attention of the amateur is focused on the animals contained, in the aquarium on plants and animals. Paludarium for the cultivation of plants. The combination of underwater and surface vegetation. Paludarium is a community of refuge and marshy plants. It contains two living representatives of the plant kingdom, which grow in nature and swim in the water, but take root in the soil and can painlessly tolerate fluctuations of the water surface until full access to the shore or drainage of the reservoir. The paludarium is a unique invention of plant lovers. In paludarium a small lake with small floating plants with a fresh green Mat form. Where there is enough space, we can include larger plants from Araceae, Ferns, Anubias, etc.

The high humidity in the paludarium is ideal for growing swamp or tropical plants as well as for many aquarium plants. For decoration, you can use hooks, better with moss overgrowth and knotted tree branches, on which many epiphytes and other plants grow very well. Poludarium — a very exotic aquarium type of interior design, and with wood or other suitable material for the surrounding inner paludarium fed, you can keep yourself to should like home flowers, orchids, etc., for you to arrange a special winter garden.


It is a combination of aquarium and terrarium, a very interesting aquarium type and it comes with different sizes. It serves for the simultaneous maintenance and display of combined Aquarium and terrarium inhabitants, who need water and land for their life at the same time, and above all it is lungfish. For the preservation of many amphibians and reptiles that lead a semi-aquatic way of life, the most suitable aquaterrarium, based on an aquarium that keeps the water well, the land in which numerous islands are represented. The water surface is small and shallow with a depth of 3-10 cm. This is sufficient for the contents of toads, frogs, tree frogs, painted toads. Soil, lighting, and vegetation suitable for the biotype are of great importance in order to create comfortable conditions for aquatic aquarium inhabitants.

As a rule, all lungfish reproduce underwater, lay eggs, hatch larvae, and their further life for a certain period in the water. Therefore, their reproduction requires a suitable combination of an aquarium and a terrarium with sufficient depth and dense vegetation throughout the room. It is desirable to have a sufficiently large terrarium built into the ground in a small aquarium. Many contain lungfish with a preferred residence underwater (some of the tropical frogs), which contains the axolotl. When optimal conditions are given, the mature individuals leave the aquarium and transform into an amphibian with keratinized skin. It is unnatural that they stay underwater for a long time, but when they mate and lay eggs, they return to the water. Similar behavior occurs in our salamanders and newts, as well as in incoming tropical lungfish representatives.

Spawning aquarium.

Spawners are usually smaller than the General aquarium. For some small fish, you can even use vessels with a bottom size of 20×20 cm, but everything depends on the type of Fish and the characteristics of spawning. Different fish species require spawning aquariums with different proportions. This can be a long aquarium divided into sections by partitions. Partitions are easiest to make of plexiglass 1-3 cm under the edge of the aquarium itself, to avoid accidental overflowing of water over the edge. The number of holes in the partitions should be sufficient for the free flow of water, and their size should exclude the intrusion of Fish and fry in adjacent compartments.

The sectional aquarium is convenient because it eliminates the need to use a variety of filters and heaters necessary for the maintenance of individual containers. It is intended for spawning fish and is needed in 2 cases – if it is important to create the conditions necessary for spawning fish, i.e. certain parameters of dH, KN, pH, temperature, lighting, as well as the necessary protection from caviar to fish, etc.; – if you need to get the greatest amount of caviar. These aquariums are usually made of ordinary or organic glass because upon contact with metal and Putty various substances enter the water, which negatively affects spawning fish and their eggs.


Auxiliary glass or organic glass containers necessary for life maintenance of the development of eggs and larvae of aquarium inhabitants. The water must have the same parameters as the water in the spawning aquarium. The internal structure meets the requirements of the farmed fish species. The capacity of those ranges from 0.5 to 25 liters. The minimum volume is required for spawning carp that lay eggs in peat; the maximum volume is required for the incubation of their parents ‘ discus eggs. The main conditions of the aquarium incubator: cleanliness, optimal temperature, hydrochemical composition, and oxygen regime. Very often a free spawning aquarium is used as an incubator.

Aquariums for growing fry.

Trough-shaped vessels, in which roasts are bred in the first months of life, should be spacious and easy to maintain. It is necessary to grow roasts, which are transferred from the incubator to the reeds at the age of about 2-3 weeks. This aquarium is also made of glass or organic glass, up to 20 cm high, and with a volume of 80 liters or more. Ventilation and filtration are already necessary here. First, the water parameters are maintained as in an incubator, and then these parameters are gradually changed to the optimal for the content of this type of fish. This aquarium can also replace the spawning Aquarium and the incubator in many cases.

Quarantine and treatment aquarium type.

This aquarium type is necessary for the quarantine of purchased fish and for the treatment of sick individuals with suspected diseases. Even if your fish is already sick, it will be much cheaper to treat it in a small aquarium than to pour half a can into your 200-400 liters size at the same time. Snails and shrimps cannot tolerate such “treatment” at all and there is a chance of losing the entire population, which in turn leads to losses not only morally but also financially.

Restored, usually made of ordinary or organic glass, without soil, and without plants, equipped with heating, ventilation, and filtration. Depending on the fish species, this reservoir should offer the maximum possible space for swimming. About such an aquarium you need to place a lamp or another lamp that can observe the well-being of the patient on request. Do not forget the cover glass, as most fish can successfully jump.
