Cylindrical lamprologus, previously referred to as Neolamprologus Adriani, hails from Lake Tanganyika in Africa, preferring to stay in the coastal zone of the island of Malas. This fish prefers impressive depths and is found on 25 meters, where it finds crevices and rubble stones.
This cute fish has a very interesting and attractive color in the form of alternating bands of black and purple flowers. When light hits the side of the fish, the attention is drawn to the neon outflow of the fins and the bright shading under the eyes.
Depending on which region of the lake the fish lives in, the colors and shades may differ.
The standard body length of a cylindrical lamprologus is about 10 to 12 centimeters, but some males can reach 15 centimeters in length. Most large males may have a small wen.
Females are more modest in size, rounded fins.
To contain a group of 10 individuals, you need an aquarium with a volume of 150 liters, equipped with a powerful filter and densely planted with long-stemmed plants with rigid leaves and a powerful root system (spiral vallyseria, lemongrass, sinnema).
I would like to note that the cylindrical lamprologist does not tolerate “old water” and rather painfully react to a sharp change in hydrochemical parameters. Accordingly, when changing, you should be careful, every week to replace no more than 1/3 volume.
Fresh water must necessarily stand for several days and have similar chemical parameters.
Like other predators, lamprologists prefer food of animal origin – coretil moth and zooplankton organisms. In addition, the fish eat a good dry food from the company Tetra, with a big appetite picks up from the surface of the granules and flakes of dry food.
Only when feeding watch the dosage, because the fish are prone to overeating and may die.
Parameters content Neolamprologus Adriani:
- Water hardness 8 – 12 degrees (maximum allowable 25 degrees);
- Active medium reaction 7.2 – 8.5 pH;
- Water temperature 26 – 27 degrees.
If you need to grow healthy producers, you need a flock of fry in the amount of 10 to 12 individuals, among which you need to select half of the largest and healthiest fish. To grow the producers, you need a common aquarium for cichlids, but in an ideal scenario, it is better to keep these fish separately.
Puberty comes to a year of life. By this time, the body color is already stabilized.
The fact is that young animals very often in stressful situations can completely discolor, and in adult fish colors, contrast and stripes can fade altogether. The dorsal and anal fins are lengthened until thin braids appear.
As practice has shown, more stable spawning with maximum fertilization is obtained only when the fish reach the age of one and a half years. Until this point, there are periodic marks, during which the percentage of fertilized eggs does not exceed 60.
The males of these lamprologists are polygamous, and aggressive leaders can spawn with several females at a time.
In aquariums, in addition to standard shelters in the form of ceramic and plastic tubes, bricks, ceramic flower pots and plants, de pots with small side openings commensurate with the head of lamprologists should be present. The fact is that hydrobionts feel more relaxed if he completely hides in a pot and only his head looks out, controlling the situation around him.
If there is strong competition for territory in the aquarium with lamprologists, the males will leave their shelters only if they need to refresh themselves. Accordingly, in order to minimize the number of skirmishes for the territory, it is desirable to place in the aquarium more such shelters so that their number exceeds the number of fish in the aquarium.
The male leader is given the most “trump” shelter, near which females are constantly spinning. The remaining inhabitants of the aquarium are located in other shelters, trying to stay away from the leader of the pack.
The stimulus to reproduction is the increase in water temperature to 28 degrees, followed by lowering it to 25 – 26 degrees. Squid meat, mussels, beef and fish should be included in the diet.
Before spawning, the couple acquires a bright color, and the female begins to fuss actively around her house, while the male accelerates around the annoying neighbors. The first spawning is restless than the next.
The female refuses to let the male into her shelter until the last moment. When the male gets inside the shelter, then we can assume that spawning will succeed.
One female lamprologist is able to bring up to 120 eggs, which are glued to the walls of pots in the form of neat and compact masonry. The practice of maintaining a cylindrical lamprologist has higher rates – about three hundred eggs, but this is a great rarity.
The laying is protected by the female, which may not even leave the shelter to have a snack. Males rarely replace females on the nest, and they do it without much hunting. At the first opportunity, the male, on the contrary, tries to push her back onto the clutch.
With a three-day interval, the male can spawn with several females.
An aquarist may encounter some difficulties in growing young stock in a common aquarium. As soon as the fry begin to swim on their own, they immediately undergo attacks by their neighbors in the aquarium, or by the attacks of their parents.
It is best to incubate the eggs in a special 20-liter aquarium, in which a filter with a weak aeration should be installed in the opposite corner from the stall. It is better to use water for an otsadnik from a spawn, to which it is necessary to add methylene blue to a weak blue color.
The substrate with caviar is carefully transferred to the incubator, positioning it so that the eggs are on top. If the laying was carried out on a stone, then it is desirable to arrange it vertically. Caviar is whitish and at first it may seem that it is not fertilized.
However, a few days later, at a water temperature of 28 degrees, the tails begin to move in the larvae. Within a couple of weeks, the larvae will hang on the walls of the pot.
By the end of the second week, the young ones make the first attempts to move around the substrate and after some time are distributed along the bottom of the aquarium, as there is still a small margin. It is necessary to start feeding the young stock in advance, until the yolk sac has resolved in the fry.
Noplia of Cyclops and Artemia, as well as “live dust” are suitable as food.
It is likely that in nature, lamprologists spawn simultaneously with the rapid development of zooplankton. Accordingly, the fry of lamprologists are famous for their voracious temper and they hardly tolerate even the slightest feeding delays. Fry quickly “dry out” and drag on.
Of these individuals often grow thin fish.
The first 10 – 12 days young need to be fed twice a day. However, the best regimen is four times divided feedings. The main condition is to prevent the constant presence of food in the pitcher.
This can lead to overeating and death of fry, as well as uneaten food can spoil the water, which is also very bad. A few weeks after the start of feeding, the fry reach a length of 1 centimeter.
At this time, their color is gray-beige with a golden sheen on unpaired fins. On the tail fin there is a yellow spot, which disappears when the fish reaches 4 months of age, and the body length will be 3 centimeters.
In adult fish, yellow color is completely absent.
By two or three months of life and body length up to 3 centimeters in fish, the first signs of banding appear. By this time, lamprologists can safely eat larger types of food, for example, chowder, which is eaten by lamprologists with great pleasure. Also, the fish make the first attempts to swallow small moths and, in principle, their diet will not differ from the diet of adult fish.
In the subsequent maintenance and cultivation, there are no problems with feeding.
