Many dream of buying an aquarium that captures the beauty of the underwater world. The soothing sound of water, the slow swaying of plants, and the elegant silhouettes of fish make it the perfect decoration in any room.
With today’s technology, you can purchase a nano aquarium kit, ideal for those who lack space for large aquariums. However, finding inmates who feel great in such a small space can be a problem.
We will discuss the best choice of fish for nano aquariums of less than 10 liters.
So, what kind of ornamental fish are frequent inhabitants of nano aquariums?
Small, elegantly colored pygmy catfish reach a size of 3 cm – females and 2.5 cm – males. It is enough to simply distinguish the female from the male, due to its completeness and larger size, the males are slimmer and smaller than the females. The color of the fish is grayish, along the body from the mouth, bordered on the top and bottom by two pairs of antennae, and to the base of the caudal fin a black stripe runs, ending at the tail with a small dark spot.
Black stripes are edged with white stripes above and below it. From the anal to the ventral fin there is a small black stripe.
The back is gray, much darker than the abdomen, which is green. The fins are transparent.
For the maintenance of Corydoras pygmaeus suitable aquarium of 10 liters, in which you can run a flock of 4-5 fish. However, the most comfortable pygmies feel in a species aquarium in the amount of 10-15 individuals. Soil is better to use loose, loose, dark tones.
It is also necessary to have shelters in the aquarium, which are good for snags, coconut shells, shards, etc. Plants are better to plant around the perimeter of the tank so that there is a place for swimming.
The aquarium should be equipped with a filter and a compressor as the corridors like to rummage in the ground, lifting dirt from the bottom. It is necessary to replace weekly 30% of water.
Water parameters: pH 7.0-7.2, DH to 20
Water temperature: 20-26 ° C
Fish picky, eat both dry and various live and frozen food. Food is mainly taken from the bottom, as well as from the leaves of plants, but can rise and swallow it from the surface.
When feeding should be borne in mind that the pygmy corridor has a small mouth, so the size of the food should be small.
Dwarf catfish are very interesting in their behavior, in contrast to other members of the Koridoras genus, they can often be seen as a floating flock in the water column, they also like to relax on the wide, horizontal leaves of plants and stones. Thanks to their activity and schooling lifestyle, Corydoras pygmaeus deserved the love of aquarists.
A flock of these wonderful catfish will decorate any aquarium, but because of their small size, you should keep them only with small peaceful fish (for example, some types of small tetras, iris, etc.). When arranging an aquarium, it is necessary to take into account that, like all corridors, catfish have intestinal respiration, therefore, there must be access to the surface of the water to trap air. It is not recommended to plant an aquarium with them with plants with finely dissected leaves, as catfish during the search for food rummage in the ground raising sludge, which is deposited on the foliage of the plants.
Fish become sexually mature and ready for spawning at 4-8 months, as a rule, males mature earlier than females. The female lays from 30 to 50 eggs, sticking them one by one on the walls of the aquarium and the leaves of plants.
To stimulate spawning, you can add fresh water. There are several ways to breed pygmy corridors.
First way – it contains a small flock of catfish (12 and more) in a species aquarium, densely planted with plants, where under good conditions they will successfully divorce themselves, without much intervention from the outside, because the pygmies do not eat their eggs and fry. Aquarist can only feed the young juveniles as they develop and grow, without removing the producers from the aquarium.
Another way – one female and 3-5 males are deposited in the spawning aquarium (from 10 l), although pair spawning is also possible. To stimulate spawning for 15 days in the evening, 15-50% of water is replaced with a simultaneous decrease in its temperature by 1-3 ° C. Spawning process can last a whole day.
After spawning, the producers are immediately deposited and the temperature in the spawning area is increased by 1-3 ° C.
Corydoras pygmaeus females, as a rule, choose well-lit objects for gluing eggs, so you can use glass leaning against a well-lit wall of the aquarium and the other glasses darken as a substrate. Fishes will choose illuminated glass for spawning, which, together with the delayed caviar after spawning, is transferred from the spawning to the incubator.
To avoid caviar rotting in water, add a solution of methylene blue to a pale blue color.
Growing fry: The larvae hatch after 4 days, 3 days after hatching, they can be started to feed infusoria, and as they grow they can be transferred to Artemia nauplii. Juveniles of dwarf catfish pygmy of three weeks of age begins to develop much slower.
The color of the fry differs from the color of mature individuals.
Perhaps one of the most popular species for miniature aquarium hobby is rasbora. And in their family we can distinguish a wonderful, beautiful fish called “micro-erythromicron microselect” (Microrasbora erythromicron).
With a size of only about 2.5–3 cm, it is ideal for a small tabletop reservoir. This micro-collection, brought to us from Myanmar, was opened not so long ago, but it has already gained wide popularity due to the ease of keeping it in small volumes of water.
The fish has a cute tiger color: transverse light stripes pass through the entire gray-blue body, transparent fins have a reddish tint.
There is nothing particularly difficult in the content of this rasbora:
- optimum temperature – from +22 to +28 degrees,
- neutral water hardness
- its weekly replacement in the amount of 20–25%,
- filtration and moderate aeration.
It is not necessary to create a strong current in the “bank”, since the erythromicrons like calm water.
For normal maintenance in a small aquarium there must be a zone of vegetation or at least some floating plants.
The fish feeds on natural conditions by zooplankton, and in captivity it is fed usually with frozen cyclops, daphnia, and commercial dry feed for carp fish.
Alone, this micro-sampling is boring, so it’s better to have a small flock of 4-5 individuals.
Also known as Siamese fighting fish, the Cockerels are considered the first domestic fish, and this is undoubtedly based on their stunning appearance and ease of care. Males can have an infinite range of colors, patterns. Their small size makes them an ideal candidate for a nano aquarium.
But, despite its size, the Cockerels have tremendous waywardness. They are one of the few fish that will interact with their owners, which makes them attractive to people of different ages.
Male males should live separately. They are fighting fish and are selfish in an aquarium; they will patrol every inch of space, like a king ruling his castle.
However, less temperamental cockerels may tolerate small, dull fish that live in the lower part of the aquarium, as long as they do not pose a threat to the cockerels.
Females may be placed in groups of 5 or more to form a flock. Although they also prefer to be alone.
Maximum size: 7.5 cm
The minimum size of the aquarium: males – 3 liters. Females – 10 liters
The maximum length of the fish is 6 cm, in an aquarium it usually does not exceed 5 cm. The main body color is yellow-green. The double dorsal fin is divided by a small gap, the first one is much smaller than the second one.
Males of Popondetta furcata are quite easy to distinguish from females, they are brighter and with an elongated dorsal fin. The dorsal and anal fins in males are transparent with narrow yellow margins. Anal and pectoral fins often with a red tinge.
The blades of the caudal fin have yellowish stripes with a black border at the top and bottom border. In females, the tail fin lobes are yellowish in color, while the pectoral and anal fins are transparent.
Pseudomugil furcatus differ from most other forms of Pseudomugil from Australia and New Guinea by a more deeply forked tail fin, for which they received the name – Fork-tailed Blue-eyed.
An aquarium with a volume of at least 40 liters is suitable for keeping poponette. A large number of plants should be planted in the aquarium, which should be better positioned along the side and rear walls to allow free space for swimming.
It is also desirable to have floating plants, as these fish like to be closer to the surface. You must have a filter that creates a current.
It should be regularly, at least once a week, replace the water.
Water parameters: pH 6.0-8.0, DH 5 – 12
Water temperature: 24-28 ° C
You can feed any dry quality food, but especially love frozen and live food. When feeding, you should consider the size of the feed, as these fish have a small mouth. For better health and health should be fed varied.
Eat mainly in the upper layers of water.
Moving, very colorful, schooling fish with a peaceful nature, floating in the upper and middle layers. It is better to keep a flock of at least 6 individuals (preferably an equal number of males and females) with other peace-loving species of fish, such as tetras, danios, rasbora and medium-sized bottom fish. Males can sometimes be aggressive to females, if kept in pairs, keeping in a group with a predominance of females will help reduce aggression.
In any case, there should be enough plants in the aquarium so that the females can hide. Popondetta furcata is susceptible to velvet disease (oodinium), which is provoked by “old” water and with a large accumulation of nitrite in water.
Regular water changes, washing the filter and a varied diet will help preserve the health and beauty of these wonderful fish.
Reproduction is quite simple. Spawning is planted in a small aquarium in the ratio of 2-3 males to 8-10 females, which contributes to a greater number of deferred caviar and gives females a break from vigorous grooming males. The variant of spawning by a pair is possible, but in this case one should monitor the behavior of the male, who may not like the female.
He can be very aggressive towards her and she will suffer. In this case, replace the female.
Males during spawning behave very interestingly, swim with vertically set anal and dorsal fins and compete with each other.
As a spawning substat, Javanese moss is excellent, on which the eggs stick well. Marriage games begin in the morning, one female sweeps 5-10 eggs at a time, once a day.
Eggs of Popondetta furcata, despite the small size of the fish, are rather large. Substrate with caviar after spawning should be transferred to the nursery aquarium with water from the spawn, as producers can eat caviar and fry, and in its place put a new one. As a rule, fertilized eggs produce no more than 75%, this percentage decreases if the producers are poorly fed.
Unfertilized eggs should be removed, and methylene blue should be added to water. In spawning and nursery aquarium weak filtration is desirable. Larvae hatch will occur in about 10-15 days.
The water level in the rearing aquarium should be low. It should be increased with the growth of fry.
This still rather rare fish in domestic nano aquariums is perfectly suited for small volumes of water. The fact is that the average size of an individual does not exceed 20 mm.
The rarity of badis (dario) is due to the fact that breeders have not yet brought out the ornamental views of this Indian little beauty, and in pet stores it almost never happens. Most often, you can purchase such a fish under the order.
That is why owners of this species can rightly be proud of the presence of Scarlett in their nano aquarium.
The color of the fish is bright and memorable:
- across the silvery shiny body are bright red broad bands;
- the fins are also painted red, with a narrow blue strip running along their edges. This applies to males.
- As for the females, their color is much paler, and on the abdomen there is a slight reddish spot.
Dario dario is unpretentious to environmental conditions and maintains a solid range of temperatures: from +16 to +26 degrees. The optimum temperature is 23-25 degrees above zero.
Unfortunately, in nature and in captivity, a badis lives just over 1 year.
However, in the conditions of a small domestic pond, females spawn well, thanks to which one can hope that the “Indians” will continue to delight their masters.
This fish is one of the lesser-known nano fish in the aquarium hobby. These fish love aquariums with heavily planted plants and with slow movement of water.
Males in many ways exhibit habits of cichlids during spawning. They spend their time dancing around a female, and will fiercely protect their spawn.
Elassome Evergladay is somewhat difficult to maintain, as they mostly love live and frozen food.
Maximum size: 2.5 cm
The minimum size of the aquarium: 5 liters
Owners of nano aquariums are well known for small fish originally from Southeast Asia. An individual of the carp family in nature reaches a size of no more than 3 cm, and at home about 25 mm.
Appearance – characteristic of all carp:
- laterally oblate body;
- olive green, and on the sides from the middle of the body to the base of the tail there are black or dark blue stripes of irregular shape;
- dorsal fin low,
- the tail is a perfect V-shaped with sharp rays.
This analysis is different peace loving and gets along well with other calm fish. 3-4 individuals will normally feel in a 15-liter aquarium, but it is better if it is rectangular in shape, because these agile fishes need a place for “walking”.
In food, the fish are not picky and normally eat various small food: daphnia, artemia, bloodworms, branded dry food for carp.
Comfortable water temperature should be maintained in the range from +23 to +26 degrees, effective and strong aeration is mandatory. Acid-base balance should be from 5.5 to 7 units.
Known by many names, dwarf gourami are miniature, beautiful, and calm nano fish that are becoming more and more popular. Along with bright colors, many owners of dwarf gourami are surprised by the loud cawing and noise from these little fish!
Calm water, dark soil and background will contribute to a brighter color of these fish. Like all gouras, males can be aggressive towards each other, so it’s better to keep more females than males in an aquarium.
And, since these fish belong to the Labyrinth family, make sure that they have access to the surface, as they complement the need for oxygen from the air.
Maximum size: 2 cm
The minimum size of the aquarium: 5 liters
This exotic fish from Central Africa is sure to decorate any small aquarium. It is also called the pike-clown because of the very bright multi-colored color and some external similarity with the common pike.
True, the size of this African is much smaller – no more than 3.5-4 cm. And the females are even smaller.
Epiplatis cannot be confused with any other fish due to the tail. Large, bright red colors with blue stripes – it really looks like a torch.
Pike clown peaceful and calm. However, it is able to jump out of the water, so the aquarium should always be kept closed.
He likes soft water with a temperature of 23-26 degrees above zero and a neutral pH.
The fish picks up food only from the water surface, therefore feed (artemia, cyclops, daphnia, dry branded mixtures) should be given in small portions.
Known by many names, this unique fish and, perhaps, the best choice for a nano aquarium. Although the fish does not differ in bright coloring, it is one of the smallest fish in the world!
They are very shy, and can be food for other inhabitants of the aquarium. They are best kept with representatives of their own species. The males of Formosa can be placed together, cases of aggression are very rare.
Females in their form are very unique when it comes to breeding. They give birth to 1-2 fry per day, for about 10 days.
The minimum size of the aquarium: 3 liters
Representatives of this family of fish, which includes about 30 species, are considered to be among the smallest. These crumbs, which are 1.5–2 cm in size, fell into aquariums from the Mekong River Basin.
They do not differ in bright coloring. On the contrary, grayish colors with shades of pale yellow color is not remarkable.
What can they be interested in fans of nano aquaristics?
- First, they give very viable offspring. Apparently, the conditions of natural habitat contributed to the development of a strong immune system.
- Secondly, female horns after spawning retain eggs under the belly. Bound by the finest threads, the eggs hang under the belly of the female for a long time. She swims with these original “clusters”.
The fish is quite unpretentious and feels good in a large range of temperatures: from +17 to +26 degrees. Water should be neutral in both pH balance and hardness.
It feeds a peace-loving Orizias dry food, as well as daphnia and artemia. Lifetime in an aquarium can reach 3 years.
There are many kinds of nanoribs, and in each specific case one should proceed from the possibilities of content and personal preferences.
Nano aquarium is convenient, inexpensive, takes up little space. Only this does not mean that you can pay less attention to the living conditions of its inhabitants.
On the contrary, it is necessary to treat all recommendations and requirements for maintaining the delicate balance of a small aquatic ecosystem with particular thoroughness.
