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.

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.

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.

  • 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.

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 will become more, it is possible to 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.

Melanotaenia Bozsemen's Rainbow

Comfortable parameters for water content: 24-28 ° C, dH 10-200, pH 7.0-8.0. Aeration, filtration and regular replacement of up to one third of the volume of water in the aquarium is necessary.

Description:

Rodnia - New Guinea ponds.

Fish size: males up to 10 cm, females up to 8 cm.

The body of the fish is oval, high, slightly elongated and compressed at the sides. The tail fin is two-bladed. The front part of the body is painted in a brilliant saturated blue color, the back in yellowish-orange. Between these two areas, there are alternating light and dark vertical stripes. Females of melanotenia are painted much paler.

It is a peaceful, active and jumping fish. It can be contained with many non-aggressive fish (zebrafish, ternii, etc.).

Feeding aquarium fish must be correct: balanced, diverse. This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses. Article "How and how much to feed aquarium fish" talks in detail about this, it outlines the basic principles of the diet and feeding regime of fish.

In this article, we note the most important thing - feeding fish should not be monotonous; both dry and live food should be included in the diet. In addition, you need to take into account the gastronomic preferences of a particular fish and, depending on this, include in its diet ration either with the highest protein content or vice versa with vegetable ingredients.

Popular and popular feed for fish, of course, are dry food. For example, hourly and everywhere can be found on the aquarium shelves of food company "Tetra" - the leader of the Russian market, in fact, the range of feeds of this company is striking. In the "gastronomic arsenal" of Tetra are included as individual feeds for a certain type of fish: for goldfish, for cichlids, for loricarids, guppies, labyrinths, arovan, discus, etc. Also, Tetra has developed specialized foods, for example, for enhancing color, fortified or for feeding fry. Detailed information on all Tetra feeds, you can find on the official website of the company - here.

It should be noted that when buying any dry food, you should pay attention to the date of its production and shelf life, try not to buy food by weight, and also keep the food in a closed state - this will help avoid the development of pathogenic flora in it.

Iris

The iris is an aquarium fish, belongs to the family of Melanothy. The natural habitat of its habitat is Australia, New Zealand, and ponds of the islands of Indonesia.

In the coloring of the fish there are the brightest colors of the rainbow and their original combinations. The brightest fish is the iridescent in the morning. At this point, the colors become extremely saturated, and acquire a neon glow. Under stress, the iris becomes silvery gray. Stress can cause transportation of the individual, photography with a bright flash. In order for the colors not to fade, the iridescent should be surrounded by attention, ensure rest and good nutrition.

The content of the iris

Different types of iridescent fish live in lakes, marshes, mountainous or forest streams, in freshwater bodies, and also in reservoirs with brackish water because of the proximity of the ocean. The averaged parameters of water were determined, where any iris would feel comfortable: water temperature is from 22 to 28 degrees, a neutral acidity index (pH 6.5-7.5). Water hardness can vary: from extremely soft to hard (10 - 16 units). Water is recommended weekly to replace about a quarter. The volume of the aquarium - at least 50 liters.

For the good health of the fish in the aquarium, you must install a filtration and aeration system. Care should be taken also about high-grade lighting.

The irises are schooling fish, so you should start at least 6 individuals at once. They lead a fairly active lifestyle, for this they need sufficient space. Therefore, do not occupy a large aquarium space with plants and decorative elements. In the course of active games, the fish can jump out of the water high enough, so the aquarium should be covered from above.

Feeding

The iris has no special nutritional requirements. They eat good food live, frozen or dry. In the preparation of the diet should follow a balance. It should be remembered that the predominance of dry feed can provoke various diseases. From live food, all types of iris irons perfectly eat the shrubber, small bloodworms, small crustaceans, and insects. Be sure to include in the diet of vegetable feed, otherwise the iris will nibble aquatic plants.

A flock prefers to eat food from the surface of the water, or is in its thicker. From the bottom of the fish feed prefer not to take. Therefore, the feed should be given so that the flock ate it completely.

The most common types of iris

Neon iris

Neon iris The most common type of fish. With suitable illumination of the side of a moving individual, they flash with bright blue or blue hues.For the sake of this effect, aquarists contain a neon iris. The body of the neon iris has a characteristic hump and keel on the chest. In the conditions of an aquarium the size of small fishes reaches 4 - 5 centimeters. Their heads are somewhat flattened, and large eyes stand out on it. Neon iris is unpretentious in nutrition, but does not like sudden changes in water. Stressful conditions contribute to various diseases of the fish.

Three-striped iris

Three-striped iris. It has received no less widespread in aquariums than the neon iris. Small fishes of this species reach sizes up to 10 centimeters, therefore a large artificial reservoir is necessary for them. Three-striped iris was given a name by its characteristic color: on its sides there are three longitudinal stripes.

Iris popondetta - bright fish, reaching a size of 5-6 centimeters. It is characterized by the characteristic color of the tail: in the middle of the fin is transparent, and expressively colored at the edges. Therefore, the poponettuta iris is also called the iris forked.

The original coloring is famous for Boesman's iris - the front half of the body is bright blue, the back half is orange or scarlet.

Neon iris fish: breeding, feeding and compatibility

Recently, neon iris has become one of the most popular aquarium fish. Suitable lighting allows this resident of the underwater world to flash bright blue and blue hues. It is for the sake of this unusual effect that many aquarists get neon irises. Under natural conditions, these fish inhabit the waters of the Mameramo River, which is located in Indonesia and is reported to the Pacific Ocean. Neonov's iris iris was brought to Europe only in the 1990s, after which they became frequent inhabitants of home aquariums. The size of the fish in such conditions reaches about five centimeters.

Description of neon iris

This fish has a small flat head and rather large eyes. On her back there is a characteristic high hump, which is more pronounced in males. The dorsal and anal fins are usually paired. In females, one can observe a full abdomen, while in males it is flattened on both sides. The neon iris fish doesn’t stand out by its color, since there are neither stripes nor spots on its body. However, on close acquaintance, the true beauty of this underwater inhabitant manifests itself: when light hits, each scale explodes in bright colors, and a dark edging further enhances this shining effect. While moving, the body of the fish then extinguishes and then flashes again, only the yellowish-red fins remain unchanged.

It should be noted that neither the time of the day, the spawning period, nor the emotional state of the fish affects the brightness of the coloration. Neon iris with all its unassuming form is very attractive. It spends most of the time in the middle water layers, it does not pinch the plants and does not dig in the ground, which makes its content very simple and unpretentious.

Rules of the maintenance of neon iris

For a comfortable life of fish, it is recommended to select an aquarium not less than 45 centimeters in length, since neon iris women prefer to swim horizontally. Water should be first defended, as too hard water can cause a deterioration in the health of the fish, and even their death. The temperature in the aquarium should be around 24 degrees, although in nature the neon iris can withstand higher rates, but it is better to avoid such adverse conditions.

It should be noted that this fish is very calm and peaceful. Most effectively it looks in an aquarium with dark shallow soil and densely planted with various plants, among which it is necessary to build a similarity of islets for more free swimming. There are no special requirements for the choice of underwater flora. In addition, the neon iris is easily exposed to bacterial diseases, so quarantine measures must be observed, for example, to remove the fungal plaque that appears on the fish's head with methylene blue with added salt.

Breeding fish

The stage of puberty neon iris reaches the age of 8-9 months. For breeding fish should purchase a separate small aquarium, the water level in which should not exceed 35 centimeters. Small-leaved plants are placed in the tank, and they also provide uninterrupted illumination and aeration. Manufacturers are choosing the most well-fed and bright in color fish of both sexes. Before spawning, they should be kept separately and intensively fed, often changing the water and raising its temperature to 28 degrees.

After transplanting fish into spawning fish, active spawning continues for up to three days, after which the production of offspring does not occur so intensively. Over time, the female is able to sweep up to 500-600 eggs, which have a sticky thread and settle on the leaves of plants. After spawning, the parents are returned to the large aquarium, and the dead spawn, which has acquired white color, is removed. After a week, the first larvae should appear, and after another couple of days, fry will form from them, which should be fed with infusoria and crustaceans. Fry of neon iris become their unusual neon coloring in a month and a half.

Fry food

For feeding the appeared offspring are suitable:

  • artemia;
  • microhills;
  • egg yolk;
  • microencapsulated feed;
  • lyophilized liver;
  • sliced ​​enhitrei;
  • pipemaker

Feeding adults

Neon iris, the photo of which cannot fully convey all the sophistication and beauty of this fish, is quite unpretentious in its diet. She well perceives dry, frozen and live food, and also loves to eat fine bloodworms, insects, pipe man and various crustaceans. It should be noted that it is often dangerous to give dry food to small fish, because it can provoke serious diseases that will eventually lead to death.

Compatibility with other fish

Neon iris perfectly coexist with many other aquarium fish. They do not offend or persecute anyone, but it is advisable to refrain from neighborhood with very small individuals in order to prevent them from eating. The company from such aquarium fish as barbs, angelfish, catfish, discus, roosters and gourami is perfect for iridescent irons. The life expectancy of neon iris at home can reach five years, which is quite a lot for such an inhabitant of the water element.

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 are kept 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. The problem is in interspecific crossing, in nature they do not interbreed 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 quite rare species, it is desirable to keep different types of iris separately ...

Aquarium fish Iris

Looking at aquarium fish, people often think that they are less whimsical than cats or dogs, and require much less care and waste of time. But this is an erroneous opinion, because for a beautiful and diverse aquarium you need to take into account a large number of nuances in order to keep it in proper form. And in your free time, just admire the fruits of your labors.

After all, even fish of the same breed may require completely different care. For example, the family of iris has about seven genera, each of which is distinguished by its individuality.

The body of a fish like the iris is red, elongated and high, the sides are flattened, the eyes are large and the lips are thick. The dorsal and caudal fin consist of two parts. The color of young fish is significantly different from the color of adult fish. Young fish are completely silvery, and now adult fish have a bright red color, and only a small number of scales remains silvery. In the aquarium with good care can live up to 7 years.

Iridescent Bosman. These fish, albeit aquarium iris, but their appearance is very different from their relatives. The body of this fish is oval and high, slightly elongated, the sides are flat. The color of the front part of the fish is silver, and the back part is bright yellow.

Cherry iris Aquarium fish iris cherry from their relatives differ mainly in color, they are completely brownish-golden, with two distinct stripes on the sides.

Iris hunchbacked. It has an unusual dorsal fin, which in its form resembles a hump. The color of this fish is bluish-silver, a dark stripe stretches from the eye to the tip of the tail.

The iris is red-striped. It has a silver color with a snowy blue tint, a very small specks of red color, which are located closer to the belly of the fish, form a longitudinal strip.

All types of iris are different from each other mainly in color, but they are very peaceful in nature, live in flocks, behave actively, are particularly distinguished by their jumping ability, so the aquarium with this type of fish must be kept closed.

These fish have an increased sensitivity to the oxygen content in the water, therefore aeration is very important for them. In the diet, the iris prefer live food, but they can be fed with dry food, as well as plant food, but not for long, the main ration should be live food, otherwise the color of the iris tarnishes noticeably.
