Nannakar Fish


Nannakar neon - some questions

The neon nannakara (also known as Blue Neon nannakara or electrician, is found in the writing of nanocara, in English Nannacara Neon Blue) one of the most poorly described fish in modern aquarism. Despite the fact that a couple of such fish live successfully with me, I did not want to write about them, since there is practically no reliable information. However, readers regularly ask about it and I would like to summarize more or less accurate information about this fish. I hope you will describe your experience in the comments.

Habitat in nature

In the process of collecting information, there was even the opinion that this fish from the wild nature appeared in the USSR in 1954. This, to put it mildly, is not so. Neon nannakars appeared relatively recently and definitely do not occur in nature. For example, the earliest mention in the English-language Internet refers to 2012. Here begins the complete confusion associated with these fish. For example, in its description, the leading supplier of aquarium fish Aquarium Glaser is confident that nannakara electrician does not belong to the genus Nannacara, and probably originates from Akara bluish-mottled (Latin Andinoacara pulcher). The information that this hybrid is imported from Singapore or Southeast Asia is slipping, which is most likely true. But who became the basis for this hybrid, while there is no clarity.


Again, most often they say that this is a small fish. However, it is not small. The male I grew up about 11-12 cm, the female slightly its smaller, and according to the sellers of the fish can reach larger sizes. At the same time, they are very broad, if viewed closely, then - let it be a small, but strong and powerful fish. The color of all the same, bluish-green, depending on the lighting of the aquarium. The body is colored evenly, only on the head it is gray. The fins are also neon in color, with a thin, but pronounced orange band on the dorsal. Eyes are orange or red.

Content difficulty

The hybrid turned out very, very strong, unpretentious and hardy. They can be recommended for beginner aquarists, but only if there are no small fish and shrimps in the aquarium.


Omnivorous fish, with pleasure eats both live and artificial food. There are no problems with feeding, but nannakar neon is gluttonous. They love to eat, drive away from the feed of other fish and relatives, are able to hunt shrimp. They show not hefty mental abilities and curiosity, they always know where the owner is and look after him if they are hungry.

Content in an aquarium

Despite the name nannakara, which implies small size, the fish are quite large. An aquarium for maintenance is better than 200 liters, but you need to consider the number of neighbors and their appearance. It is obvious that the electrician does not have any particular preference in the content of the nanocara, since there are many reports of successful content in different conditions. Fish hold the bottom, occasionally hiding in shelters (I have it snags), but in general are quite active and noticeable. The content options can be called pretty roughly:

  • Water temperature: 23-26 ° C
  • Ph Acidity: 6.5-8
  • Water hardness ° dH: 6-15 °

The soil is preferable to sand or gravel, the fish do not dig it, but they like to look for remnants of food in it. By the way, they don’t touch the plants either, so you don’t need to fear for them.

Compatible with other fish

Neon nannacars are described as timid fish, but this is completely wrong. Apparently, their character depends on the conditions of detention, neighbors, the volume of the aquarium. For example, in some they slaughter an angelfish, in others they live quite calmly (including me).
My male attacks his hand while cleaning the aquarium and poking it is quite noticeable. They are able to stand up for themselves, but their aggression does not spread farther than the jabs of congeners or competitors. They do not pursue, do not kill or injure other fish of similar size. Similarly, they behave in relation to their relatives, periodically demonstrating aggression, but not arranging fights.

Nevertheless, it’s definitely not worth containing them with small fish and small shrimps. This is a cichlid, which means everything that can be eaten will be swallowed. Neons, rasbory, guppies - potential victims. Significantly increased aggression during spawning and in a small amount of neighbors can notably fall.

Gender differences

The male is larger, it has a steeper forehead and the dorsal and anal fins are elongated. During spawning, the female develops egg-laying. However, the sex is often extremely weak and can only be recognized during spawning.

Male and female


I do not undertake to describe the conditions of breeding, as there was no such experience. The couple living with me, although showing pre-spawning behavior, spawn did not postpone even once. However, they are definitely easy to breed, as there are many reports of spawning, and in different conditions. Fish spawn on a stone or snag, sometimes dig a nest. Both parents take care of the fry, take care of them. The fry grows quickly and eats all kinds of live and artificial feed.

Nannakara Neon

A quick bright flash, a neon aperture behind the glass of the aquarium, a multi-colored beam that attracts attention - this is how you can describe this small, but very beautiful fish. The neon nannakara will become a unique and noticeable decoration of your aquarium.

A bit of history

Neon Blue Nannacara (Nannacara Neon Blue or simply Blue Neon) is a dwarf fish introduced to Europe at the beginning of the 20th century from South American countries.

In Russia, it appeared a little later, in 1954, and immediately gained popularity among aquarium lovers. Understanding national love is easy, because this type of fish is calm, peaceful, unpretentious and at the same time extraordinarily beautiful.

Temperament and compatibility with other inhabitants

Do not be afraid of strife and fights among the inhabitants of aquamira, as nannakara has a friendly and non-aggressive nature. Because of its unpretentiousness in the content, blue neon is perfect as a novice who is just beginning to learn the basics of aquarium art, as well as a professional who is ready to easily grow even squid.

Large cichlid species, in the family of which nannakara belongs, are distinguished by special behavior. They are not at all like representatives of other breeds. In addition to the fact that these fish are not quite easy to maintain, they can easily turn the life of other inhabitants of the aquarium into hell.

And these creature creatures like to dig in the ground and weed the underwater garden at their discretion, so they often cause the grown plants to die with love.

Numerous offspring of large cichlids can make the owner feel remorse, because selling all the fry still does not work out, and you have to leave them in the general aquarium or simply use other large fish as food.

Dwarf cichlids, to which the heroine of the article belongs, help to avoid these inconveniences.

They owe all their advantages to a small height (on average, an adult neon-nannakara reaches 9 cm). With such sizes it is difficult to dig the roots of plants (they seem huge to them) and to conflict with their neighbors. Thus, they become ideal candidates for creating an ornamental aquarium.

But lovers of shrimp and snails (not in gastronomic terms) are not recommended to contain neon nannakara along with their pets, because the fish will enjoy them for dinner with pleasure. Although, if, for example, coil snails have become a serious problem for the flora and fauna of the underwater kingdom, the nannakara will become an excellent orderly for an aquarium dwelling.

It is not recommended to contain a dwarf cichlid with large and aggressive fish that can take it as food.

The only drawback of the fish is that it becomes very hostile during spawning. If the male is not removed from the aquarium in time, provided that it is not large enough, the female can easily kill him. She jealously guards her caviar and attacks anyone she sees within a radius of 25 cm from the clutch.

For the rest of the time, the nannakar gets along easily with its diverse neighbors. In a small aquarium it is recommended to keep a couple of individuals - a male and a female. If the size of the aquarium allows, then you can start a flock - several females and one male. Not vice versa, because the main thing in the house of this type of fish is always female. The male is needed exclusively for reproduction.


Externally, blue neon retained all the features inherent in the representatives of this species. The only difference is in bright pearl-blue shade of scales with a golden shade. Gold pours the head and upper back.

The fish has an oblong body, slightly compressed at the sides, and proportionally curved lines of the back and abdomen. The long dorsal fin stretches almost from the head to the tail.

The shape of the fin can determine the sex of the individual: in the female, it is neatly rounded at the end, and pointed in the male. In addition, the male has a narrow red or dark stripe along the upper edge of the dorsal fin. The individual male is more brightly colored and grows up to 8 cm, and the female reaches only 6 cm in length.

Conditions of detention

Aquarium. For this type of fish suitable capacity of 70-100 liters. Like all other inhabitants of the reservoirs, nannakara loves space, so she will be grateful to you for the larger displacement of the house.

Shelters. A fish is cowardly by nature, therefore, at the sight of something unfamiliar to it, it prefers to swim and hide rather than boldly swim and examine an unknown object. Shelters in which a coward could easily hide and wait out the danger would be useful. Stones and snags, castles, caves and flower pots will be welcomed by the fish. In addition, the pet will use nooks not only as a place for hiding, but also during spawning.

Plants It is better to plant in the corners of the aquarium and at its back wall so that the fish has room for maneuvers. Do not interfere and floating on the surface of the plant. As the soil, you can use fine polished gravel with a layer of 2-5 mm. It is not necessary to make special strengthening of the roots, as the fish does not harm the flora by swarming in the ground.

Water temperature should be 22-26 ° C, gH 5-20, pH 6-7.5, and do not forget about filtering, aeration and weekly replacement of 1/5 of the water.

Feeding It should also not cause difficulties, since nannakara eats with the same appetite both live food (mosquito larvae, daphnia, cyclops), and special food for fish from the pet shop.


It is easy to get offspring from nannakaras. For throwing caviar and hatching fry from it, it is necessary to provide some conditions that are not very different from the usual ones. The water temperature should be 24-27 ° C, pH 6-7.5, the usual rigidity.

At one time the female lays 50-300 eggs in the dark secluded corners of the aquarium. Then the male quickly fertilizes them and swims away. This is where his mission ends. From this point on, the care of the offspring is completely transferred to the female.

She carefully fanned the masonry with fins and guarded her against uninvited guests, including her father. During this period, the male is best transplanted into another aquarium or tank, because a caring mother can simply kill him. There were cases when the father jumped out of the aquarium, fleeing from the persecution of the latter-day mom.

After three days, the calf is transferred by the mother to a hole in the ground specially dug for her, and after 5 days the fry appear, which the mother leads through the space of the dwelling, teaching the basics of survival. During this period, you can feed new inhabitants with rotifers, Cyclops larvae or Artemia.

Once the fry were born, you can return the male back, but you need to be prepared for the rivalry between the parents for the right to care for the offspring. In the struggle, the male often wins, and, having assumed the coloring of the female, dad takes on the responsibility of the mother.

Nannakara neon is a very beautiful and very simple fish in its content. She will be an excellent pet for a beginner in the aquarium business, will help him to believe in his own strength and not to give up the initiative at the very start.

Nannakara Electric Blue content and care

Habitat in nature

The eight-band cychlasma was first described in 1903. She lives in North and Central America: Mexico, Guatemala, Honduras. It inhabits lakes, ponds and other bodies of water with weakly flowing or still water, where it lives among the crowded places, with a sandy or muddy bottom. It feeds on worms, larvae, small fish.
The English name of this tsikhlazomy - Electric Blue Jack Dempsey (Jack Dempsey), the fact is that when she first appeared in amateur aquariums, she seemed very aggressive and active fish, and she was nicknamed after the then-popular boxer Jack Dempsey.
Blue Dympsey cichlid is a color morph of the eight-striped cychlasoma, brightly colored fry slipped among the young, but were usually rejected. Actually, it is not known for certain whether they appeared as a result of natural selection or hybrids with another kind of cichlids. Judging by the intensity of color and slightly smaller sizes, this is a hybrid. Despite the fact that the breeding of Blue Dumps cichlids is quite simple, it is not often possible to meet them for sale, as fish is an amateur.


Like an ordinary eight-stripe, an electrician's body is stocky and compact. They are slightly smaller in size, grow up to 20 cm in length, while the usual up to 25 cm. Life expectancy of 10-15 years.
The difference between these fish in the intensity and color of color. While the eight-streaked cichlid is rather greenish, Blue Dempsey is a bright blue. Males develop long dorsal and anal fins and rounded black spots along the body. Does not add to the popularity and the fact that the fry completely dull, light brown color with slight patches of blue or turquoise.
Color is typed with age, especially strong and bright color during spawning.

Content difficulty

Simple and adaptable fish, but you can meet good specimens not so often. Beginners can also keep it, provided that the fish live in a separate, specific aquarium.


Omnivorous, but prefer live food, including small fish. Bloodworm, tubule and artemia completely arrange them. Additionally, you can feed with artificial, in particular, granules and sticks for cichlids.

Content in an aquarium

This is a rather large fish and for a comfortable maintenance an aquarium of 200 liters is needed, if in addition to them there are still fish, then the volume needs to be increased. Moderate flow and powerful filtration will be superfluous. It is advisable to use an external filter, as the fish create a sufficient amount of waste, turning into ammonia and nitrates.
Blue Dempsey Cyclose is able to live in a wide range of conditions, but it is believed that the warmer the water, the more aggressive it is. Most aquarists try to keep it in water with a temperature below 26 ° C, to reduce aggressiveness.
The bottom is better sandy, as they gladly dig in it, with a large number of kryagi, pots, shelters. Plants are not needed at all or unpretentious and stiff-leaved - anubias, echinodorus. But they are better planted in pots.

  • Conditions for content:
  • minimum volume of the aquarium - 150 liters
  • water temperature 24 - 30.0 ° C
  • ph: 6.5-7.0
  • hardness 8 - 12 dGH


Although eight-strip cichlids are very aggressive and are not suitable for keeping in a common aquarium, the Electric Blue Jack Dempsey is quieter. Their aggressiveness increases with age, and like all cichlids during spawning. If fights with neighbors are constant, then, most likely, the aquarium is cramped for them and you need to transplant a couple into a separate one.
These fish are definitely incompatible with all smaller ones (characteristic and small carp neon types), relatively compatible with equal-sized cichlids and well compatible with large fish (giant gourami, knives, pangasius) and catfish (black bargus, plecostomus, pter) .

Gender differences

Males are larger, they have a long and pointed dorsal fin. The males have a rounded black dot in the center of the body and another one at the base of the caudal fin. Females are smaller, painted paler and have less black dots.


Spawning in common aquariums without problems, but often the offspring is pale colored and unlike parents even in adulthood.
