A small round, but such a cute aquarium!

Often, when we think of aquariums, we picture a small, circular aquarium. These adorable and small tanks can bring a little peace and beauty into any space. They are ideal for people who adore the concept of raising fish but are space-constrained or prefer a straightforward setup. These aquariums can display a vibrant underwater world and be just as captivating as larger tanks, despite their smaller size.

Beginning fish keepers or anyone wishing to keep a few small fish should use small round aquariums. Because of their small size, they can easily be placed on a countertop, desk, or shelf to add some decoration to your house or place of business. They are also less complicated to maintain than larger tanks, which makes them an excellent choice for those who lead hectic lives or are new to the hobby.

These aquariums need careful planning and attention to detail despite their small size. Choosing the appropriate fish, plants, and décor is essential to establishing a balanced and healthful space. A tiny round aquarium can become a gorgeous focal point that infuses your daily life with a little bit of nature with the correct maintenance and imagination.

Despite its apparent simplicity, a small round aquarium adds a special charm to any space. Its curved glass gives a clear, uninterrupted view of vibrant fish and plants, and its small size makes it ideal for small spaces. These aquariums can be easily maintained with the correct setup and offer a calming atmosphere in addition to being aesthetically pleasing. A small round aquarium can be a delightful addition to your home, combining beauty and functionality, whether you’re an experienced or novice aquarist.

How to keep a small round aquarium?

Many aquarium enthusiasts voice stereotypically unfavorable opinions regarding the upkeep of small aquariums. and so cause people’s souls to become confused. Negative arguments primarily focus on how small aquariums’ biological systems are unstable and how creating a nitrogen cycle is impossible. The remaining arguments—that he is round, inconvenient, and t.D.—are, in reality, incidental and emotional-subjective.

Let’s put an end to the problems! Thus, you must begin with the reality that life itself is breathed into a drop of water by nature, aided by its biological instruments. What do you suppose the aquarium’s volume is below?

A tiny aquarium with two 2-liter IAPLCs

The author placed 188th out of 2000+ entries in the largest international competition for aquarium design, IAPLC, with an impressive two-liter aquarium.

The example provided indicates that a 5–10 liter volume is typically a whole testing ground for creativity and nature.

About the "betta maniacs" who arrange their cocks in stacks on a stand holding five to ten liter aquariums, what can we say? The cockerels live and please their owners with the brilliant colors of their amazing tails, and for some reason they are doing well.

Having said that, let’s consider: perhaps the aquarium isn’t the issue? But then what? The solution is straightforward: the person who created and manufactured the aquarium world is the issue. We are, after all, the only ones who can truly ensure the wellbeing of any aquarium. Now let’s examine how to maintain a tiny aquarium correctly!

So, the first, most important and common mistake of novice aquarists when caring for such a small aquarium – weekly change of 100% of aquarium water and, accordingly, 100% renewal with fresh water. This is a fatal mistake, leading to torment and suffering, both the aquarist and his pet! These actions nullify all the efforts of Nature. You need to understand that the biobalance of the aquarium (biological equilibrium) – is a set of factors of aquarium life, upon reaching which, the aquarium begins to work like a clockwork. That is, when all aquarium aquatic organisms: fish, plants, mollusks, crustaceans, bacteria, fungi and others, interacting with each other, create a certain chain, so to speak, a closed cycle, in which the aquarium becomes a whole, healthy, tuned organism.

There will be helpful links to resources that provide more information about establishing a biobalance at the conclusion of the article. We will state in brief in this article that it is NOT ALLOWED to empty the aquarium of water! For this aquarium, weekly water changes should be made in the range of 20–30% of the total volume, without accounting for evaporation. By taking such steps, we "refresh the water" while also abiding by Nature’s cycles and processes.

The soil is the second crucial component of small aquarium maintenance. Any aquarium’s soil is crucial because it serves as a starting point for the biotic purification process, which keeps the water free of toxins like nitrogen compounds NH4, NO2, and NO3. This is because the majority of nitrifying bacteria reside in the soil. By "eating" poisons along the chain and oxidizing them to a gaseous state, these bacteria, which are directly involved in the nitrogen cycle, eliminate the poisons from the aquarium.

Here are the main requirements for the soil: layer thickness 5-7 cm., light, porous substrate. Colonies of beneficial bacteria will develop well in such a substrate, since the thickness, lightness and porosity will contribute to their settlement and the creation of optimal conditions for their life. This is due to the increase in area due to the lightness and porosity of the substrate, in other words, there will be more "houses" where bacteria and other beneficial microorganisms will live. These "houses" will be comfortable, bacteria and other organisms participating in the nitrogen cycle, in fact, all are aerobic or have a mixed type. That is, for their existence, oxygen access is needed. A light, porous substrate will create a water flow in the soil and thus the substrate will constantly have access to O2 molecules.

The third important aspect is the availability of a technical base for a small aquarium: a filter, aeration, a heater. This equipment is extremely important for any aquarium. The issue with filtration and aeration in the aquarium Tetra Cascade Gloube is 100% solved – due to the presence of a waterfall filter in the kit, which is quite enough for filtering and aerating a small volume. Note that you cannot turn off this filter, for example, at night, so that it does not make noise. Note that Nature does not have a lunch break from 13.00-14.00 There are no holidays and weekends! If Nature took days off, it is unlikely that our world would be so bright and full of diversity of life! So we must always maintain the flow of water and aeration of the aquarium.

If you’re still bothered by the murmur of the aquarium, the Cascade Globe aquarium kit comes with a plastic tongue that you place on the waterfall to muffle the sound of the water falling. Though you can turn it on at night, it’s generally preferable to pick a location in the house where the noise from your own little paradise will be at most minimally bothersome at night.

Regarding the small tank’s temperature regime, this is also a very significant issue. First of all, the majority of the aquatic species that inhabit our aquarium are visitors from the tropics, where the average annual temperature fluctuates between 22 and 27 degrees. Our pets experience stress at varying levels. Furthermore, temperature has a direct impact on water’s properties and all living things’ metabolisms. For instance, a one-degree increase in water temperature causes a significant decrease in the concentration of oxygen, which is necessary for all living things—not just bacteria—and increases the danger of nitrogen compounds by making them more "nuclear."

We are lucky to live in a time of rapid technological advancement, as it makes controlling the temperature—even in a tiny aquarium—very easy. A mini-heater, such as the mini-heater Laguna, is installed in a small aquarium during the winter. These heaters are currently widely available in the pet supply market.

A small aquarium cooler for the summer months, when it gets hot. A fan like that can cool water by two to three degrees.

How to care for a small round aquarium?

We have thus successfully mastered the art of maintaining a tiny aquarium. Even in the smallest aquarium, you can replicate a stable biological system by following the guidelines mentioned above.

Nonetheless, maintaining such a reservoir is an equally important issue. We only perform a partial water change; we don’t empty the entire tank. We’ve had enough of these.

It is also advised that you never remove or clean the gravel from your aquarium. Unfortunately, a lot of people frequently act in this way. All beneficial biology in the soil is eliminated by such actions. Keep your hands off the aquarium’s bottom until you are certain that detritus—organic and inorganic particles that build up in the soil but do not participate in the biological cycle—has considerably filled the soil and, as a result, decreased the soil’s aeration. Simply use a mini-siphon—which you can purchase or make yourself using unconventional materials—to sweep the soil when this occurs (google it).

Indeed, within a week, the aquarium walls can become overrun with a variety of organisms. Simply wipe the aquarium’s walls with a toothbrush once a week prior to changing the water. Use fresh water that has settled for 24 hours when changing the water.

Aquarium water tests should always be available for anyone who values both their aquarium and themselves. We suggest using test strips, such as Tetra 6in1, for this kind of aquarium; we think they will be adequate and less problematic. Of course, drip tests are another option.

What fish can be kept in a small round aquarium?

Fish for a tiny aquarium

We will merely enumerate the candidates who can be retained in small quantities in this section.

The first and most popular fish are cockerels and other bettas. These fish are unpretentious in content, breathe atmospheric air, slow. Under natural conditions, they live in swamps, puddles, on the rice fields of Asia. This is why they do not require large volumes. In addition, the flock of the cockerels is virtually impossible – this is a loner fish. It is not without reason that they are called fighting Betta, in these fish intraspecific aggression is pronounced, the males fight and kill each other on duels, even females can be killed by hotel-mights just like that, we can say due to a bad mood. Even in the period, it would seem marriage games … After spit, the female immediately puts from the male otherwise the despot will mercilessly beat his beloved.

Given these characteristics, cocks are the first choices for small-volume single-chamber content.

GUPPI and GUPPI Endler are the second-place contenders. Also veil fish, small and slow. Their fertility is the only disadvantage when it comes to a small aquarium volume. Similar to rabbits, these viviparous fish give birth. Regarding which, it is preferable to retain 2-3 males and eliminate females, considering our volumes.

All tiny tetras and rasboras make up the third platoon. The only thing to note is how quick and nimble these fish are. They are not very appropriate in a small reservoir in this sense.

Fish and chips are the fourth item on the list! Indeed, Apistograms are great representatives of the dwarf cichlids, so why not?

Fish like danio, Iriatherina werneri, afyosemions, gambusia, cardinals, limia, microbora, nothobranchius, pseudomugili, and so on can all be kept in a small round aquarium. However, shrimp and snails are two other aquatic species that will thrive in our tiny aquarium.

All that matters is to always keep in mind that we are accountable to those we have subdued!

Arrangement of a small aquarium world

The Tetra company’s article "How to create conditions for fish in 5 steps" about the Tetra Cascade Gloube aquarium was published in YandexJournal and is provided below to help you understand the density of the material.

Tiny spherical globe for aquarium cascade

It is cheap and nearly hassle-free to keep an aquarium at home. You can easily order anything you need online. The cost of the aquarium, water, and plant products, food, plants, and fish is 6,500 ₽. 4 months of care are included in the price. The costs are accurate as of June 6, 2018.

Duration: sixty minutes.

Level of difficulty: beginning.

Equipment includes a 6.8-liter Tetra Cascade Globe aquarium, a 10-milliliter syringe, a thin hose, standard scissors for pruning off old leaves, and tweezers for planting.

Materials and specialized tools: Tetra soiletra Active Substrate, Tetra Betta AquaSafe preparation, Tetra Crypto fertilizer, Tetra SafeStart bioculture, Tetra Betta Larva Sticks food, and Tetra EasyBalance product.

Tetra TH digital thermometer, Tetra FN aquarium net size S, Tetra EasyWipes wipes, and Tetra Easy Crystal Filter Pack C 100 filter cartridges are all in stock.

Installing the aquarium and unpacking takes ten minutes.

The ideal choice for a small space is a small round aquarium that can hold one fish and is affordable to maintain. Cost: roughly 3,000 ₽.

The aquarium needs a location that won’t disrupt the home. It is not a good idea to put the fish next to the battery because the fish can get hurt by sudden temperature changes.

After deciding on a location, unfold the aquarium and set it up on a level, sturdy surface.

Set up the décor and dirt — fifteen minutes.

We will require one-third of a package (approximately 400 ₽ for three liters) of Tetra Active Substrate soil, which is made of sintered clay. Soil with particles between three and five millimeters in diameter is ideal for a small aquarium because it will support beneficial bacteria that will clean the water and roots of the plants.

As long as the decor and soil don’t react with water, it doesn’t matter what color they are. You must drop vinegar on a pebble or snag to test for neutrality; if it hisses, a reaction is occurring. Such décor or soil will increase the amount of unnecessary algae in the water and make it too hard for fish and plants to live in.

After laying down the dirt, give the aquarium’s décor a quick rinse under running water.

It is preferable to include tiny stones and snags in a small aquarium or not use any at all.

Ten minutes to pour water.

Considering that the soil and decorations occupy 0.8 liters of the aquarium, pour 6 ml of Tetra Betta AquaSafe. The bottle has measurement marks on it. Although a minor overdose poses no risk, it is advisable to use a medical syringe to prevent errors. Using an aquarium net, agitate the water. The product’s leftovers should not be thrown away because you will need them for water changes.

Fish can quickly adjust to a new environment thanks to the vitamins and beneficial substances found in Tetra Betta AquaSafe. About 180 ₽ is the cost. Regular Tetra AquaSafe can be used, but only 3 ml is needed for our 6-liter aquarium, which is half as much. The price won’t change in any way.

Plants on land: 15 minutes.

Simple, slowly growing plants are ideal for our aquarium. For instance, a Thai fern costs between 150 and 300 ₽, while Cryptocorin Wendt costs roughly 300 ₽.

Plant pots made of plastic should be cut with scissors to remove the old, rotten leaves. After removing the cargo and mineral wool, the roots should be chopped to a length of 3–4 cm.

We plant cryptocorin by putting in the roots and half of a Tetra Crypto fertilizer tablet in the soil between the bushes. It must be added once every month. Ten tablet packages are available for 300 ₽.

When we plant fern, we merely cover it with soil from above and do not plant the roots deeply.

Fish should be cooked in five minutes.

Pour 7 ml of Bio-culture Tetra Safestart after shaking the bottle. Bacteria in the composition clean water and shield fish from poisoning by releasing waste products from their essential activity. It costs about 250 rubles for 50 ml.

After the filter is installed, we connect the power supply to the network.

Fish population: five minutes.

Since female bettas lack such vivid and lengthy fins, a male will reside in our aquarium. He adjusts to people very quickly and can even learn to accept food from hands. Because bettas come in a wide variety of breeds and colors, their prices range from 100 to 1000 ₽. Our fish amounted to 400 rubles. We switch on the light and let the fish go. It is crucial for the health of the plants that it burns for eight to ten hours every day.

After settling in, you can feed the pet the following day to give it time to adjust to its new surroundings. Red worms are similar to Tetra Betta Larva Sticks, which are food for betta fish. Give no more than two to three pieces once daily. Fish that are overfed run the risk of becoming ill and dying because the leftover food taints the water.

Betta fish are best kept alone because they are hostile toward other people. Food and all products should be kept out of children’s reach. Do not purchase food in reserve because one 100 ₽ sachet will last for two to three months. Once opened, the food starts to oxidize and lose vitamins.

Alternate the water on a regular basis.

After using a thin hose to empty out one-third of the aquarium on the third day following launch, replenish the water to the same temperature and add one milliliter of Tetra AquaSafe. A water hose is something you can buy for about 160 ₽ or find at home. Replace one-third of the water again on the sixth and ninth day following launch. The following time—after five days, or on the fourteenth day following launch.

The aquarium’s microflora will reach maturity two weeks after launch. You can now begin doing weekly water changes or use Tetra EasyBalance, which will only require two annual changes. Make sure to shake the bottle before using a syringe to extract 1.5 ml of the product, or one ml for every 4 liters of water. Place the item inside the aquarium. Since an overdose is undesirable, we use a syringe.

Maintain the aquarium’s cleanliness.

You’ll need a size S net to fish out extra food and dead plant leaves. Only in cases of illness or emergency in the aquarium can you catch the fish. The microflora will perish if you move the pet into a different container without first cleaning the entire aquarium and the soil.

Once a month, the filter cartridges in the Cascade Globe aquarium need to be changed. Three pieces for 350 ₺ in a package.
