Habitat of Nannakara Anomalies
Nannakara anomaly - representative of the cichlids of South America. They are found in nature from the Aruka River in Guyana to the lower Marowijne River in Suriname. Inhabit the territories of flooded meadows and lowlands of coastal areas. Most of the fish that come to us are grown on farms in the Far East and Eastern Europe.
Description of Nannakara Anomalies
The body of the fish is elongated, slightly compressed laterally. The dorsal fin is large and starts from the gill cover and ends at the root of the tail. Unlike females, in males the dorsal and anal fins are pointed at the ends, in females they have a rounded shape. Eyes red or yellowish red, pupil black. Coloring male yellowish-green with small three coal brownish spots on each flake. Along the lateral line of the fish’s body, you can often see horizontal stripes that appear due to scales with black dots. But the color of the caudal fin has a bluish-green color with a red border and a white border. Females have a more faded greenish-brown color. Before spawning, the color of the females changes. On the body appear 2 horizontal brown stripes 7 - 8 vertical, a bit like a chessboard. Males are noticeably longer than females, their size is about 7.5 cm, females - about 4 cm.
Nannakara Compatibility Anomalies
Very peaceful dwarf Cichlids. Can be kept in a common aquarium with various peaceful fish: Terence, Tetra, Danio, Gourami, Swordsmen, catfish etc. However, it is worth remembering that females are able to show aggression during the spawning period.
How to feed Nannakar anomaly
In the nature of Nannakara, anomalies are typical representatives of micro-predators, who gladly feast on worms, insects and various invertebrates. Individuals living in aquariums eagerly eat both live food and high-quality dry food designed for Cichlids. Moreover, if you use specialized dry food as the main one, then it is necessary to add vegetable feed containing spirulina to the diet. Not scalded will be scalded cucumber, cabbage leaf, zucchini. Of live food, bloodworms and artemia are best suited.
Popular and popular feed for fish, of course, are dry feed. For example, every hour and everywhere you can find on the aquarium shelves the feed of the Tetra company - the leader of the Russian market, in fact the assortment of feed of this company is amazing. Tetra's “gastronomic arsenal” includes individual feeds for a certain type of fish: for goldfish, for cichlids, for loricaria, guppies, labyrinths, arovans, discus, etc. Tetra also developed specialized feeds, for example, to enhance color, fortified or to feed 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 manufacture and shelf life, try not to buy food by weight, and also store food in a closed state - this will help to avoid the development of pathogenic flora in it.

Nannakara containment conditions anomalies
I would like to immediately note that if you have a small aquarium, it is best to keep one pair of these fish. A large aquarium contains several females and only one male. The fact is that the Nannakara females guard their territory, and if another male swims onto it, then they will constantly chase after the stranger, and can even kill him.
This species feels good in small aquariums, about 60 liters, densely planted with living plants with free space for swimming, combined with snags and grottoes, acting as shelters. As a species of wood, it is best to use driftwood made of bog oak and mopane. But as a soil - gravel with a fraction of 4 mm in dark color is suitable. Anomalies populate the middle and lower layers of the aquarium.
Breeding and propagation of Nannakara anomalies
Breeding Nannakara anomalies is not a big deal. The recommended water parameters must be observed. One female is needed per male. Large aquariums are used for breeding, where several different females are attached to one male. Each female needs her own “sub-territory” at the bottom of the aquarium measuring 40cm by 40cm. The fish reaches puberty in 8-10 months.
A Nannakara female is capable of sweeping up to 300 eggs, which are immediately fertilized by the male. After this, the male is better to plant, since the female becomes very aggressive and can harm not only other fish, but also the male. The incubation period of eggs is 3 days. And already on the 5th – 7th day, the fry begin to swim and can eat artemia nauplia and cyclops.
Interesting to know:
1. The name "Nannacara" has the meaning of "Small Acara" (Little Acara).
2. Nannakars are widely distributed in trade and are well suited for a novice aquarist who is interested in Cichlids. The anomaly is a very attractive and hardy fish.
3. It is interesting that this species, like some types of Apistograms, is characterized by a very exciting “body language” of the female for communication with fry during their growth.
4. Nannakara anomalies are characterized by male dominance and the presence of a subdominant individual female, which, in the absence of a male, within a week, becomes a full-fledged dominant male.
All of the above is just the fruit of observing this type of aquarium fish and collecting various information from owners and breeders.

Medium-sized fish: 6 - 9 cm. But some individuals grow to 10 - 12 cm.
External characteristics of an adult:
- the body is elongated, slightly flattened from the sides,
- the dorsal and abdominal lines are smoothly curved,
- the dorsal fin is long, reaching to the tail,
- eyes are red or orange.
The main remarkable feature in the description of the appearance of Nannakara is the bright blue iridescent scales. Under certain lighting conditions, golden tints may appear on the dorsal scales.
Living in nature
Nannakara Blue Neon - a breeding product, does not occur under natural conditions. The first mention in the catalog is noted in 2012, that is, the species is young, and not dividing into subspecies.
It is impossible to say exactly how and by whom the wonderful aquarium fish, which was popular with aquarists all over the world, was bred. It is believed that the hybrid was created by Singaporean breeders when crossing American cichlids. According to another version, the view was obtained by crossing the turquoise turquoise and bluish-spotted.
Care and maintenance
Like all cichlids, Nannakara prefers a spacious habitat. Therefore, for a pair of individuals, you should take an aquarium with a volume of at least 70 liters. If you plan to settle the fish in a common tank, where other species live, then the volume should be at least 200 liters, otherwise the neon "handsome" will begin to fight for the territory.
The fish are quite lively, curious, but not capricious, non-aggressive. They watch with interest the owner walking around the room, understand and react when he comes to give food.
Nannakar aquarium fish are one of the most mysterious and vibrant inhabitants of home tanks. The phenotype has a lot of names: neon acar, neon blue and others. But, whatever the name of this exotic fish, it remains special and unique, adorning artificial ponds.
The origin of the fish is still unknown. According to the generally accepted version, Nannakara Blue Neon is a hybrid that was bred by crossing cichlids from Central and South America. The result of breeding was the rare and interesting Nannakara Neon Blue, which instantly gained popularity among aquarium enthusiasts. In natural habitats, this fish can not be found.
According to the second version, the Nannakara electrician was created as a result of breeding work with turquoise and bluish-spotted acar. The first mention of an unusual hybrid appeared in 2012, so this phenotype is considered young in the aquarium.
According to the external description, the Nannakar cichlid is very similar to the typical representatives of the Cikhlov family. The fish stands out against other phenotypes with a juicy blue body color with a gentle pearly tint. The body is slightly compressed laterally, the dorsal fin is long, and stretches from the head to the tail. Eyes of an orange shade, on the head there are several scales of cold gray color.
The dimensions of Nannakara are medium - the length of the fish reaches from 9 to 15 cm. Sexual dimorphism is weakly expressed, it is possible to distinguish between males and females by the dorsal fin: in males it is slightly pungent, sometimes it has a scarlet hue. In females, the fin is more rounded. In addition, male fish are more powerful and larger, and also have an intense color.
At home, Nannakara Electric Blue is able to live up to 5 years, if the fish has good living conditions, quality care and a balanced diet.
Nannakara blue neon, despite its brightness and exotic origin, is unpretentious and hardy, so experienced and novice aquarists are happy to keep the fish happy. Cichlids perfectly adapt to various conditions of the aquatic environment, however, before acquiring the phenotype, it should be borne in mind that they need a spacious and roomy tank for swimming. The optimal water parameters are as follows:
- Temperature - 23-26C.
- Acidity - 6.5-8 pH.
- Hardness - 6-15 dH.
In addition to water parameters, for the successful propagation of neon nannakars, it is necessary to provide the following conditions for fish:
- Aquarium - given the size of the phenotype and the love of space, a large tank with a capacity of 80-100 liters is required to contain two cichlids. With a specific content, the dimensions of the tank significantly increase - up to 200 liters. The aquarium must be equipped with a lid.
- Soil - sand or pebbles of medium size can be used as soil for an aquarium with nannakaras. Some aquarists mix several types of substrate, adding marble chips. It is important to note that such soil can be used if only Nannakars live in the aquarium.
- Scenery - movable blue acars need various decorations and shelters, therefore, equipping the underwater space, you can not skimp on vases, figures, caves and pebbles. If the owner plans to decorate the tank with driftwood, it is better to give preference to those made of stained wood. In addition, for throwing eggs, Nannakars require flat, smooth stones.
- Vegetation in the aquarium is planted sparingly: on the one hand, fishes like to hide between thick algae, and on the other hand, Nannakars need a lot of free space for swimming.
An important part of the improvement of the aquarium is the installation of a high-quality filter and aerator for filtering and saturating the aquatic environment with oxygen. Otherwise, the fish will not live long. Water changes should be made weekly, updating 25% of the volume. Lighting is set to moderate and diffuse, so that the neon blue nannakaras are comfortable and cozy.
Nannakara Blue Neon, despite its delicate appearance, has a predatory nature, and is very voracious. Fish enjoy food with all kinds of food: frozen, dry and alive. Neon Akara shows special love for live food, so you can feed the fish with the following products:
- Bloodworm and daphnia.
- Larvae, cyclops.
- Sliced squid, small shrimp.
Some aquarists are of the opinion that living food weakens the health of Nannakar, so they prefer to feed fish with plant foods and dry food, which is completely balanced and safe. Also, fish are given spirulina, cabbage leaves and slices of zucchini, previously scalding them.
Blue Electric should be fed 2-3 times a day, giving small portions. It should be remembered that Nannakaras are prone to overeating, so it is necessary to carefully control the amount of food in order to avoid the development of diseases.
Character and temperament
In home aquariums, blue electricians prefer to swim near the bottom, hiding in shelters from time to time. In general, the fish behave peacefully: they do not pinch the plants, do not turn the scenery, and do not touch the neighbors. However, during the spawning period, fish can show aggression towards other inhabitants.
Compatible with other fish
Nannakara Neon is a friendly cichlid, therefore, demonstrate good compatibility with other related species of the same size. You can populate the blue akars in the aquarium:
- Somiki corridor and loricarids.
- Peaceful cichlids.
You can not populate blue cancers with large and aggressive species, as well as small fish, which the pet will take for food.
Neon Nannakars reach maturity at the age of 6-8 months, and begin to create couples on their own. Competition is often observed between them, so some aquarists plant vapors in separate tanks before spawning. Spawning of fish is stimulated by an increase in temperature by 2-3 degrees.
In the process of breeding, females toss 150-300 eggs onto pebbles, flora leaves or decorations. After fertilization, both partners take care of the offspring, however, sometimes there is rivalry between them.
After throwing the eggs, the females transfer the eggs to a previously dug hole in the ground, where it will lie for another 2-3 days. As soon as the fry are born, the babies are fed with special food for the fry, and the male takes care and protects the offspring.When the fry are two weeks old, they are sent to another container, and the parents again begin to reproduce - at Nannakar it is regular.
In some cases, neon cichlids eat eggs - this is due to malnutrition, overpopulation of the reservoir, stress and a small volume of the aquarium.
Nannakara Blue Electric is an aquarium fish of stunning beauty, which can become a worthy decoration of any artificial reservoir. Despite the exoticism and mystery, these fish are unpretentious to the conditions of detention, which makes this phenotype desirable for aquarists.
Filtration and aeration are required. With a lack of air and a deterioration in water quality, pet immunity is reduced, and infectious diseases occur. Do not forget about the weekly change of 25% of aquarium water.
The following parameters are desirable:
- temperature - 24 - 26 ° C,
- acidity - 6.5 - 8.0 pH,
- stiffness - 6 - 15 gH.
Preferably moderate lighting with a diffuse effect. No direct rays should enter the water.
You can choose any vegetation; plant an aquarium abundantly with it. But you need to leave enough space for free swimming pets. Nannakara does not touch the plants, so you can not worry about the safety of plantings.
It is advisable to select gravel with a fraction of up to 4 mm. Representatives of the species like to pick up food leftovers from the bottom, but you still need to use a siphon to clean the soil.
When arranging an aquarium, the living conditions in nature of representatives of the Cichlid family should be taken into account. The bottom must be decorated with grottoes, large stones, ceramic pots, snags. In shelters, fish relax, lay eggs.
Nannakara electrician is a predator. It is not capricious in food, but it is voracious, therefore portions should be strictly measured during feeding.
Pets eagerly eat daphnia, bloodworms, mosquito larvae. At the pet store you can buy dry food for predatory aquarium fish. It is advisable to dilute animal food with dry vegetable: spirulina.
You should not put shrimp and other small crustaceans into a common aquarium: for blue neon, they are tasty food.
Behavior and Compatibility
Peaceful behavior is characteristic of Nannakara. The manifestation of aggression is noted only during the breeding season.
The degree of compatibility depends on the size of the neighboring fish. It is advisable to choose for the neighborhood with blue neon non-aggressive fish of equal size or slightly smaller:
- chain catfish
- dwarf cichlids.
Nannakara Neon does not get along with large predators and small fish. She is afraid of the first, the second perceives as food. Also, do not hook up species with veil fins: a blue predator will leave bits from the fins.
In Nannakara, gender differences are usually unexpressed. But they become noticeable during the breeding season.
How to determine the gender:
- the male is larger than the female, a little brighter,
- he has a more curved frontal bone, longer than the dorsal and anal fins,
- the male’s dorsal fin has a sharp ending, decorated with a narrow burgundy border,
- the female has an unremarkable, rounded fin,
- during the spawning period, a female releases an ovipositor.
Breeding and reproduction
Breeding Nannakara at home is not difficult. But in the aquarium, it is necessary to create optimal conditions for spawning:
- set the temperature from 25 to 27 ° C,
- make medium acidity
- slightly increase the stiffness.
At a time, the female is capable of sweeping up to 300 eggs. She hides the future offspring in a shelter. The male fertilizes the caviar, after which it loses interest in it. Further, only the female takes care of the masonry, drives other fish away.
During this period, it is recommended to put the male in another tank. A mother, preoccupied with offspring, can attack a curious father, even mortally wound him. The fry hatch after 3 to 4 days, and the male can be returned back. But here another problem lies in wait: parents often begin the struggle for the right to care for posterity. The winner is often the father.
The fry are sensitive to the conditions of detention; water parameters must be carefully monitored. Water for substitution must be defended for 3 days. Kids eat any food intended for fry.
Disease and Prevention
How many Nannakars live depends on the quality of food and care. Representatives of the species are hardy, strong, quickly adapt to aquarium conditions. They live under optimal conditions for more than 5 years.
Diseases of Nannakara are usually associated with poor maintenance of the aquarium, inadequate filtration and aeration, and cramped living conditions. Nitrite and nitrate are extremely negative for fish immunity. To prevent pet diseases, it is necessary to change water every week, check it for the concentration of ammonia and nitrates.
If pets are sick due to stress and cramped conditions, then you need to replace the aquarium with a larger one, remove large, aggressive fish species.
Due to its unpretentiousness, endurance, complaisant and friendly nature, Nannakara became the favorite of both experienced aquarists and beginners. Fish easily breed, adapt to any parameters, so keeping them is a pleasure.
