With excellent care and attentive care melanotenii fill your aquarium with bright shine and lift your spirits with their fun games. On how to provide the conditions in which your pets will literally glow with happiness, we'll talk further.

The iris - what kind of fish?

Despite the small area of ​​natural habitat (the coast of Australia, New Zealand and some islands of Indonesia), this unusual fish, from 5 to 16 cm in length, depending on the species, has gained immense popularity among aquarists around the world.

Oblong body with high back (more often in males), large eyes, small head and short forked tail - at first glance, nothing special.

It can rightfully become an ornament to your aquarium.

Types of iris

In nature, there are more than 70 varieties of iris, but the following three are most suitable for aquarium content.

Melanotenii Bosman

Po-scientific - Melanotaenia boesemani. Its appearance resembles dawn, when the night turns into a day. The head and the front of the body are painted in sparkling blue-violet colors, and the tail part is bright orange.

Males are brighter and larger than females, can reach 14 cm in length. In poor conditions, the fish tarnish, its activity decreases, so it is very important to monitor the condition of the aquarium, which should be at least 200 liters.

These fish are not demanding to feed, because they are omnivorous, but you should add to the diet special food that enhance color.

Three-streaked iris

Melanotaenia trifasciata. Fish up to 12 cm (males are larger than females), the color on the sides can vary from bluish-green to brownish-golden.

If you keep together several individuals of this species, soon their color will become the same.

The main difference from other types of iris at this fish is a wide dark band from the eyes to the tail. Fins are red-orange in color. The dorsal fin is divided into short and long (tail) parts.

Under natural conditions, they feed on both animal and vegetable food, therefore, in captivity, they need a varied diet.

Neon iris

Melanotaenia splendida. Small (4-5 cm) fish with a wide, flat body and small head.

It has bright red fins and tail, the body is covered with silvery scales, which usually looks under dim lighting.

But it is enough to strengthen it or point it to the point, and the fish will play with blue-blue, neon highlights, which look extraordinarily beautiful in a spacious aquarium.


The content of the iris: optimal conditions

All types of melanotia need about the same conditions. Since the fish are active, they need a lot of free space. Immediately plan an aquarium of 200-250 liters.

Be sure to place natural materials, such as snags, large stones (make sure that all items do not have sharp edges), as well as hard-leaved plants that your beauties will not be able to nibble.

The rules for the maintenance of neon can be found in this article.

Fish danios at the peak of popularity of aquarists.

The key point is to maintain the desired water parameters:

  • acidity level
  • temperature 22-27 ° C
  • constant aeration with a compressor
  • filtration
  • and regular water changes (for 1/3 of the aquarium weekly).

It is advisable to let the fish sunbathe up to 2-3 hours a day. In addition, they all just look magically in bright or sunny light.

Be sure to close the aquarium! Melanenosis has a cheerful, active temper, and they can just jump out of the water.

Compatibility with other fish

The irises do not like loneliness, so it is preferable to keep them in flocks of 6-10 fish.

Peace-loving creatures will gladly share the space with other types of melanotenias, as well as with non-aggressive fish of other types similar to them in size and character.

What to feed?

Feeding the iris is a sweet affair. They gratefully eat everything that you offer them: dry food, live or frozen food (daphnia, bloodworm, tubule), vegetable food (duckweed, lettuce leaves).

Let's sum up. Whatever type of iris you prefer, remember that their beauty and health are directly related to the right care and varied feeding. Give them your care, and they will thank you with their beauty and affection!

Rainbow fish melanotenii

Boesmana

One of the most fascinating and amazingly beautiful aquarium fish - the iris. They have recently become popular in aquarism, but this does not prevent them from taking a decent position among other aquatic inhabitants. In nature, the fish live in warm shallow reservoirs of Indonesia, New Guinea, Australia.

These aquarium beauties have another name, melanotenia. The main feature of the iris is their coloring. Each species has its own unique bright color. Their content and breeding are quite simple, especially when there is experience and enough patience.

Description

The family of iris has many species, and for all the aquarium conditions are quite suitable. The fish has an oval body, strongly flattened at the sides. The shape of the fins is interesting: the dorsal forks, one part very small, the other elongated. The anal fin is located symmetrically to the long part of the dorsal. The tail is forked. Almost all species reach sizes of 9-13 centimeters. Males are usually slightly larger than females.

Under favorable conditions in the aquarium, the iris will live a full life from 4 to 8 years.

Three-strip

Kinds

  • Melanotene Boesman. Since the territories where the fish live are rather limited, it is included in the list of endangered species. At the moment, the catch and export of fish from the country is prohibited at the official level. The front of the calf is blue, with a slight purple tint. The back is orange. In the middle there is a smooth bluish border. Dorsal fin orange with greenish edging, anal - yellow with blue. Such a colorful color is typical only for males, females have a completely dark blue color with a silver shine.
  • Melanotenia three-band. The fish is distinguished by a variety of colors. It can be yellow, red, golden, blue. Its main feature is the three dark stripes on the sides. The middle strip begins at the mouth and reaches the tail. The lower and upper are less noticeable. The fins are painted in scarlet and orange tones. The fins of the iris triple-strip has a scarlet and orange. In this species, females and males are less well distinguished. Usually males are simply painted brighter.
  • Neon melanotenia. The color of the calf is pinkish-gray, with a beautiful steel luster. Under certain lighting scales casts a bluish color, which creates an unusual neon effect. In males, the fins are red, in females they are paler, yellowish. Neon melanotenia grows only up to 5-6 centimeters, so the fish is often referred to as dwarf.
  • The iris is turquoise. Another name is lakustris. The color varies from bluish to green and turquoise. In this case, the scales cast purple. The upper body is darker, closer to the blue, at the abdomen the color smoothly flows into silver-yellow or green. From the base of the tail stretches a small longitudinal dark blue stripe. The fins are blue, with black edging. Females are colored slightly paler than males. This fish is considered one of the most beautiful representatives of the family.
  • Parkinson's melanotenia. The main body color is gray steel. On the sides are bright, like fiery flashes, orange spots, smoothly moving to the fins with the tail. In this case, the tail and fins have a gray edging. There is a yellow variety, with corresponding spots. This color is also characteristic of only males, females are painted in solid steel color.
Neon

Content

This is a fairly large fish and needs space. The minimum volume of the aquarium - from 100 liters. Moreover, melanotenii are schooling fish, therefore the more individuals, the greater the capacity. Be sure to close the aquarium lid, as the fish are jumping and can jump out of the water.

It cannot be said that the iris is very whimsical, but their content requires constant maintenance of water parameters. Otherwise, the fish loses its brightness, becomes inactive and sick.

Options:

  • Temperature. All types of iris are accustomed to live in warm water. The temperature can vary from 24 to 28 ° C.
  • Acidity. 6.5-8-8 ph on average
  • Rigidity. For different species requires a certain indicator. The Boesman melanotenium and the three-band iris are 8-25dH, the neon iris is 5-15 dH, the Parkinson's iris is 5-28 dH, the turquoise iris is 8-20dH.
  • All species live in reservoirs overgrown with algae, so the aquarium can also be planted with plants. But do not overdo it: the fish need space to swim freely. Soil can choose sandy, better than dark color. On its background, bright fish will look magical. Decorative elements, stones, snags will not be superfluous.
  • In the aquarium with iris is sure to install a filter, aerator. About a third of water is replaced weekly.
Turquoise

Feeding

Melanosis feeds on both animal and plant foods. She is happy to eat bloodworms, pipe worker, Artemia, small crustaceans. You can treat the iris with high-quality artificial granulated feed or flakes. The vegetative component of food is necessary, in case of its absence hungry inhabitants of an aquarium can begin to eat up soft plants. For vegetable dressing fit cucumbers, lettuce, zucchini and food, which include the spirulina alga.

The diet is made varied and rich. Otherwise, the fish begin to grow dull and faint. Feeding them is moderate because they tend to overeat. They prefer to feed in the upper layers of water, food is not lifted from the bottom, so it is better to choose slow-sinking food.

Compatibility

Irises are very peaceful fish. Ideal for them - the neighbors are about the same size, non-aggressive, but not too timid - the iris just scare them with their energy. Sumatra, fiery and black barbs, Denison, and ternation will be suitable neighbors.

Do not forget that iridescent flocks are creatures, and in the company they feel much better. However, sometimes small fights may occur between the fish. Before serious injuries usually does not reach, but it is better to follow, so that a separate fish is not driven. You can keep the fish of the same sex, but the behavior and characters are more pronounced in the joint maintenance of females and males. In the flock is better to keep the fish of one species.

Parkinson's

Breeding

Sexual maturity of the fish reaches about 12 months. Breeding in aquarium conditions is successful, if you follow some rules.

In the spawn it is necessary to install a filter and place a lot of plants with small leaves or a sponge with cells, where the female will throw eggs. The water temperature should reach 25-28 degrees, the acidity of about 6-8 pH, hardness - up to 8dH. Parents are fed with higher quality live and vegetable foods. During the spawning period, the amount of feed increases.

One fish lays up to 250 eggs. When the female finishes spawn, the parents will be removed. Approximately in 6-7 days fry appear. Starter feed for them - ciliates, liquid feed. When they become more, you can give a microworm, nauplii Artemia.

The iris can be a real pearl of your aquarium. Their maintenance does not require a lot of energy, and if there is at least a little experience in aquarism, maintaining water parameters and feeding rules will not become a problem. A little patience, and wonderful melanotenias - be it a three-streaked iridescent, turquoise or Parkinson's iridescent - will delight with their colors every day.

Iris neon or melanotenia - shine of Borneo

The neon iris (lat. Melanotaenia praecox) or melanotenia precox is an active, beautiful and very interesting fish. It is a small iris that grows up to 5-6 cm, for which it is also called dwarf. But at the same time it is very brightly colored - pinkish-gray scales, cast at the slightest change in the incidence of light, for which they got their name.

Neon iris is quite capricious fish that can not be kept in a newly launched, not balanced aquarium. It needs a spacious and long aquarium, as neon is very active and needs free space for swimming. Of course, we need fresh water with stable parameters and substitutions. Also, the aquarium should be covered, they can easily jump out of the water.

Habitat in nature

Neon melanotenia was first described by Weber in 1922, but appeared in aquarism in the 90s. They live in small rivers and streams in Western New Guinea, and in the Mameramo region in Western Papua. The water in such rivers is clear, with a rapid flow, a temperature of 24-27C and a pH of about 6.5. They feed on melanoteny vegetable food, insects, fry and caviar. Fortunately, these areas are still one of the most unexplored on the planet, and the iris population is still not in danger.

Description

Neon melanotenia outwardly is a typical representative of the genus of iris, with the exception of perhaps sizes. It reaches a length of 5-6 cm, rarely more, for what else is called dwarf. Life expectancy is about 4 years, but it can vary between 3-5, depending on the conditions of detention. Her body is elongated, compressed from the sides, with wide anal and dorsal fins, and the dorsal is forked.

The neon iris bright fins, red in males and yellow in females. The body color is pinkish gray, but the scales are cast in blue and at different angles of illumination create a neon effect.

Difficulty in content

In general, for an experienced aquarist to contain a neon iris is not difficult. However, they cannot be recommended for beginners, as the iris is very sensitive to fluctuations in the aquarium and changing water parameters. Moreover, despite the small size, they need a spacious aquarium. This is due to the fact that it is better to keep them stained, from 10 pieces or more.

Feeding

Neon iris in nature eat both plant and animal food. In the aquarium, they are happy to eat high-quality artificial food, but it is important not to overfeed and use food that sinks slowly. Neon hardly collect food from the bottom, so fast sinking is not suitable.

Additionally, you need to feed live or frozen food: bloodworms, pipemaker, Artemia. They also love vegetable feed, you can give pre-scalded lettuce, zucchini pieces, cucumber or feed containing spirulina.

Content in an aquarium

Although they are called dwarf irises, because of their small size, they are very active and live in a flock, so it is better to keep them in a spacious aquarium with a capacity of 100 liters or more. Also, the aquarium should be tightly covered, as they are excellent jumpers and can die.

They like clean, fresh water with parameters: temperature 24-26C, ph: 6.5-8.0, 5 - 15 dGH. It is advisable to use a powerful filter, and create a current in which neon iris women love to frolic.
Best of all, they look in an aquarium that resembles their natural biotope. The sandy substrate, abundantly overgrown plants, and snags as in their native rivers in Borneo. Like most irises, neon feel great among a variety of plants. But at the same time you need a lot of space for free swimming. It is most advantageous that the aquarium be with a dark ground, and the sun's rays would fall on it. It is in such neon watches will look the most beautiful and bright.

Compatibility

Well suited for maintenance with medium-sized and peaceful fish in the general aquarium. This is a schooling fish and the ratio of males to females is very important for breeding. If you are only for beauty, then males are preferable, as they are brighter colored. Depending on the size of the pack, this ratio is better:

  • 5 neon iris of one gender
  • 6 neon rainbow irons- 3 males + 3 females
  • 7 neon iris - 3 males + 4 females
  • 8 neon iris - 3 males + 5 females
  • 9 neon iris - 4 males + 5 females
  • 10 neon iris - 5 males + 5 females

It is best to keep in a pack of 10 pieces. Make sure that there are more females per male, otherwise they will be under constant stress.
Dwarf iris eat almost everything, but at the same time almost never take food from the bottom. So you need to clean the soil more often than with ordinary fish or to get speckled catfish or tarakatumov, which will pick up the remnants of food.

Что касается других рыб, то лучше содержать с небольшими и быстрыми: суматранским барбусом, огненным барбусом, черным барбусом, тернецией, мшистым барбусом и т.д.

Половые различия

У самцов неоновой радужницы плавники имеют красноватую окраску, а у самок она желтая или оранжевая. Чем старше рыба, тем сильнее заметна разница. Также самки более серебристые.

Breeding

In spawning it is desirable to install an internal filter and put a lot of plants with small leaves, or a synthetic thread, such as a washcloth. Manufacturers pre-fed abundantly with live food, with the addition of vegetable. Thus, you imitate the onset of the rainy season, which is accompanied by a rich diet. So before breeding, the feed should be larger than usual and of higher quality.

A spawning fish is deposited in the spawn, after the female is ready for spawning, the male mates with her and fertilizes the eggs. The pair lays eggs for several days, with each spawning the number of eggs increases. Manufacturers need to be set aside if the number of caviar has decreased or they show signs of exhaustion.

The fry appear after a few days and the infusoria and liquid fry feeds serve as starter feed until they eat a microworm or nautilia of artemia.

However, it is rather difficult to grow fry. The problem is in interspecific crossing, in nature, the iris is not crossed with similar species. However, in an aquarium, different types of iris are intertwined with an unpredictable result. Often these fry lose their bright coloring of the parents. Since these are fairly rare species, it is desirable to keep different types of iris separately.

Neon aquarium iris or precox

Melanotene precox (lat. Melanotaenia praecox), neon iris, or dwarf iris - a mobile aquarium fish with an interesting color. Scales bluish-pink color, iridescent different color spectrum. Body length reaches 5-6 cm.

Keeping a fish requires adherence to special requirements, since the slightest changes in the constant parameters of water can impair its appearance and health. Melanote can not be run in a new, unbalanced aquarium. Requires a spacious environment with clean water, where you can swim freely. The fish is able to jump out of the water, so it is recommended to cover the aquarium with a lid.

Wild melanotenii precox lives in the cleanest waters of rivers and streams of Papua New Guinea, where the constant temperature is 25-27 degrees Celsius, the acidity of the environment is 6.5-8.0 pH. The region has not been studied enough, so the dwarf iris is hardly in danger. It feeds on insects, their larvae, fry of other fish, caviar and plants. For the first time this species was described in 1922. In the 1990s, the fish first appeared in home aquariums.


External characteristics

Neon melanotenia is an aquarium fish, which is now popular, the size of which in captivity reaches no more than 6 cm. In captivity lives from 3 to 5 years, depending on the conditions of life.

The body of the iris is small, narrow and flattened on the sides, the dorsal and anal fins are perpendicular to each other. Like many melanotenias, this dorsal fin has a bifurcated fin, and the tail has two lobes. The color of the fins is saturated red (in males), or orange (in females). The color of the scales is bluish-pink with a gray tint, when light hits the body, it flickers with neon glitter, for which the fish is called "neon precox".

Admire the color of neon iris.

Conditions of detention

Neon iris is a small schooling fish, which it is preferable to keep in a company of 10 adult melanotenias, or 6-8 fish. For a novice aquarist, this is not the best choice, because the iris is sensitive to changes in water parameters, it needs a spacious water tank.

Despite the dwarf size, the fish is very active. Content is possible in an aquarium with a volume of at least 100 liters, with a tight lid so that pets do not accidentally jump out. They prefer crystal clear and fresh water, with the following parameters: water temperature 24-26 degrees Celsius, water hardness 5-15o, acidity - 6.5-7.8 pH. They love the undercurrent, which is created using powerful filtering.


The most beautiful things in the aquarium look like, resembling their natural biotope in New Guinea: with thick thickets and driftwood, dark sandy soil. If several sunlight penetrates into the reservoir, the fish will acquire an incredibly beautiful body color, glaring with bright scales.

In nature, their diet consists of plant and live food, but in captivity they can eat artificial food. It is better to give slowly sinking granules - neon melanotenias will not collect them from the bottom, but they will be able to gradually eat them. From live food, you can give a pipemaker, artemia, bloodworm, from a vegetable - scalded lettuce leaves, food with spirulina, sliced ​​zucchini and cucumbers.

Dwarf iris - a calm fish, can live in a common aquarium with small peaceful fish. When buying fish of the same species, please note that the males of neon melanotenii are brighter colored than the females, you can buy 6-8 fish of the same sex. When breeding iridescents, it is recommended to buy fish per 1 female per 1 male, or 2 males for 3 females. There should be more females than males in order to avoid severe stress. Mixed sexes are best kept in an amount of 10 individuals.

The iris is compatible with non-aggressive species of fish, their content in the general aquarium has been checked with speckled catfish and tarakatums (collecting food residues from the bottom). They can cohabit with barbs (mossy, Sumatran, fiery, black), - fast and active representatives of the underwater world.

Look at the mating games of neon iris.

Breeding

As with the breeding of iris of another species, the neon iris requires preliminary preparation for spawning and the presence of a separate breeding ground. Before settling in the spawning farm, the producers are fed live food, saturated with protein, sometimes adding plant food with spirulina. A synthetic thread or small-leaved plants should be laid out on the bottom of the future nursery for fry. Install an internal filter. Stimulation of spawning occurs due to the increase in water temperature in the range of 26-28 degrees.

A pair of producers lays eggs for several days, with each new spawning the number of caviar will increase. One laying - an average of 150 eggs. When parents show signs of exhaustion, they should be deposited in a common aquarium. In 6-10 days the fry will hatch, the starting food for which is ciliates and liquid food for the fry. Then you can add Artemia naupilii, micro-worm, egg yolk to the diet. The fry of precox grow slowly, become mature at the age of 6-10 months.

Three-Striped Iris - A Guest From Far Australia

Three-band iris or three-band melanotenia (lat. Melanotaenia trifasciata) is one of the brightest fish in the family. This is a small fish that lives in the rivers of Australia and differs from other iris by the presence of dark stripes on the body. Three-striped embodied all the positive features of the family: it is brightly colored, easy to maintain, very active. A flock of these active but peaceful fish can color even a very large aquarium with bright colors.

In addition, it is well suited for beginners, as it can transfer different parameters of water. Unfortunately, the adults of this iris are rarely found on sale, and the available youngsters look a little pale. But do not worry! A little time and care, and it will appear before you in all its glory. With regular water changes, good feeding and the presence of females, the males will soon become bright.

Habitat in nature

Three-strip melanotenia was first described by Randal in 1922. She lives in Australia, mainly in the northern part. Its habitat is very limited: Melville, Marie River, Arnhem Land, and Groot Island. As a rule, they live in streams and lakes abundantly overgrown with plants, gathering in flocks, like other representatives. But they are also found in rivulets, swamps, even drying puddles during the dry season. The ground in such places is rocky, covered with fallen leaves.

Description

Three-stripes grow about 12 cm and can live from 3 to 5 years. Typical body structure: compressed from the sides, with a high back and narrow head. Each river system in which three-strip irises live, gives them a different color. But, as a rule, they are bright red, with various ebbs on the body and a black stripe in the middle.

Difficulty in content

In nature, three-lane melanotes have to adapt to different conditions in order to survive. What gives them an advantage when the content in the aquarium. They are well tolerated by different conditions and are resistant to diseases.

Feeding

Omnivores, in nature feed on a variety of insects in the diet, plants, small crustaceans and fry. In the aquarium, you can feed both artificial and live food. It is better to combine different types of feed, as the color of the body depends largely on the feed. They almost do not take food from the bottom, so it is important not to overfeed and contain catfish.
In addition to live food, it is advisable to add vegetable, such as lettuce, or food containing sprurulins.

Aquarium with various iris:

Maintenance and care in the aquarium

Since the fish is quite large, the recommended minimum volume for content from 100 liters. But, more is better, since a larger flock can be kept in a larger volume. Excellent jump, and the aquarium should be tightly covered.
Three-stripes are quite unpretentious to the parameters of water and care, but not to the content of ammonia and nitrates in water. It is advisable to use an external filter, and they love the flow, and it can be not reduced. You can observe how the flock stands in front of the stream and even tries to fight it. Water parameters for the content: temperature 23-26C, ph: 6.5-8.0, 8 - 25 dGH.

Compatible with other fish

Three-streaked melanotenia gets along well with fish of equal size in a spacious aquarium. Although they are not aggressive, they will frighten their overly timid fish with their activity. Get along well with fast fishes such as Sumatran, fire barbs or Denison. You may notice that skirmishes occur between the iris irons, but as a rule they are safe, fish rarely injure each other, especially if they are contained in a flock, and not a pair. But still, keep an eye on what would separate the fish were not chased, and that she would have something to hide.

This is a schooling fish and the ratio of males to females is very important that there are no fights. Although it is possible to keep fish of only one sex in an aquarium, they will be significantly brighter when males and females keep together. You can navigate around this ratio:

  • 5 three-stripe single sex
  • 6 triplex-3 males + 3 females
  • 7 three-lane - 3 males + 4 females
  • 8 three-lane - 3 males + 5 females
  • 9 three-lane - 4 males + 5 females
  • 10 three-lane - 5 males + 5 females

Gender differences

It is difficult to distinguish the female from the male, especially in adolescents, and more often they are sold as fry. Mature males are more brightly colored, with a hunchbacked back, and more aggressive behavior.

Breeding

In spawning it is desirable to install an internal filter and put a lot of plants with small leaves, or a synthetic thread, such as a washcloth. Reproduction of three-strip iris is active and is pre-fed abundantly with live food, with the addition of vegetable. Thus you imitate the onset of the rainy season, which is accompanied by a rich diet. So feed should be more than usual and of higher quality.

A spawning fish is deposited in the spawn, after the female is ready for spawning, the male mates with her and fertilizes the eggs. The pair lays eggs for several days, with each spawning the number of eggs increases. Manufacturers need to be set aside if the number of caviar has decreased or they show signs of exhaustion.

The fry appear after a few days and the infusoria and liquid fry feeds serve as starter feed until they eat a microworm or nautilia of artemia.

However, it is rather difficult to grow fry. Проблема в межвидовом скрещивании, в природе они не скрещиваются с похожими видами. Однако, в аквариуме разные виды радужниц скрещиваются между собой с непредсказуемым результатом. Зачастую такие мальки теряют яркую окраску родителей. Так как это довольно редкие виды, желательно содержать разные виды радужниц отдельно…

Совместимость рыбок в одном аквариуме

Compatibility of aquarium fish - a very important issue for beginners and experienced razvodchiki. Each fish has an individual character, style of behavior, regardless of whether it is a herbivore or a predator. Some fish quickly eat plants and shrimp, others attack the fish themselves. Of course, there were cases when practically incompatible species coexisted in one reservoir.

Aquarium fish compatibility chart

To systematize this issue, you should familiarize yourself with the habitat conditions of each hydrobiont, and then decide who to share it with. Assess the degree of aggressiveness of each species, the water parameters that are acceptable for them, in which layers of the reservoir they usually swim. To ensure that your aquarium is filled with life, a table is provided that lists the compatibility of freshwater fish.

Watch the video about the compatibility of aquarium fish.

Angelfish

What fish are compatible with scalar? With them you can settle the representatives of non-aggressive species of medium size. These include:

  • Barbusses;
  • Corridors;
  • Danio;
  • Gourami;
  • Botsia;
  • Mollies;
  • Pecillia;
  • Plekostomusy;
  • Iris;
  • Rasbory;
  • Labeo;
  • The Swordsmen;
  • Tetras.

Between themselves, the scalars get along quite well in the conditions of a spacious reservoir, but from the age of the young stock they must live in a group of 4-8 fish, among which they choose a mate for life, as is typical of the Cichlids. With representatives of loach fish and shrimps are partially compatible, however, the risk of cohabitation in the common tank is high. Do not settle scalar with such fish:

  • Cockerels;
  • African and South American cichlids;
  • Goldfish;
  • Discussions
  • Guppy;
  • Carp koi;
  • Astronotus.

Barbusses

Pretty active fish with predatory instinct. They can pester the neighbors in the aquarium, so they are suitable representatives of those species that are able to stand up for themselves, they are:

  • Angelfish;
  • Danio;
  • Gourami;
  • Corridors;
  • Botsia;
  • Mollies;
  • Pecillia;
  • Plekostomusy;
  • Iris;
  • Rasbory;
  • Labeo;
  • The Swordsmen;
  • Tetras.

If you notice that the barbs are pestering and driving these types of fish, consider options for moving to a spacious or separate aquarium. These fish have a very unpredictable character. It is categorically impossible to settle with:

  • Cockerels;
  • South American and African cichlids;
  • Goldfish;
  • Carp koi;
  • Astronotus.

With discussion, loach, and guppy, compatibility may be partial, depending on the line of behavior of each fish.

Cockerels

As representatives of the sub-order Labyrinths, they are distinguished by very lush and fan-shaped fins, which, perhaps, are not averse to cutting off some neighbors. The table indicates that representatives of the following types are compatible with them:

  • Corridors;
  • Danio;
  • Guppy;
  • Mollies;
  • Pecillia;
  • Plekostomusy;
  • Iris;
  • Rasbory;
  • The Swordsmen;
  • Tetras.

Cichlids

Representatives of the Cichlid family, namely many South American and African, do not get along well with other freshwater fish. In addition, they can conflict with each other if they are kept in close quarters. From a young age, they form a pair for life, so the cichlid can perfectly live on its own, or in a pair with a partner. A male and a female take care of their fry, during spawning and after it may show aggression towards neighbors. In order not to risk, settle them separately from everyone.

Corridors

Perhaps one of the most peaceful representatives of the underwater world. Does not bother anyone, he has a calm character, and where necessary, he will collect the uneaten remains of food, cleaning the bottom. The corridors get along with representatives of the following species:

Compatibility errors

  1. The main mistake is overpopulation of the reservoir. In cramped, but offended! Pisces do not understand what it means to give in to another; they inherited from their ancestors a tendency to fight for survival. A small territory, a lot of fellows, which means that there is not enough food for everyone. Therefore, it is not surprising if there were fights in a small nursery, and other traumatic cases.
  2. Incorrect zoning aquascap. Carefully read the rules of settlement of each pet: what plants are allowed, the substrate, the parameters of water.
  3. The content of large and small fish. Even a peaceful large cichlid can eat a small neighbor if it fits in her mouth.
  4. Ignoring the rules of spawning. During this period, the fish are more aggressive and sensitive. If they spawn in the general aquarium, they will be greatly disturbed, or they will eat eggs with fry. In order to avoid such cases, temporarily transfer the male and female to a separate spawn with acceptable conditions for reproduction.
  5. Wrong conditions of detention, when pets instead of pleasing the eye, gradually fade. Regular water changes, cleaning the tank, properly feeding - a guarantee of their health and a quiet life without conflict.
