Hello dear colleagues! Quite a long time has already passed since I published an article about fish from the family of kartozubyh.
And now it is time to prepare for you another interesting fact-finding material, where we will continue to study this amazing family further.
This aquarium fish comes from the southeastern part of Nigeria, where there is a clear distinction between rainy seasons and drought seasons. Afiosemion lives in shallow water bodies, the acidity of which is 5.5 – 6.8 pH. During the drought season, all small puddles dry up.
During rainy seasons, the water temperature varies between 18 and 22 degrees, but when the heat sets in, the temperature can increase to 26 degrees and the fish spawn immediately begins.
The maximum length of males is 6 – 10 centimeters, females are slightly smaller. The head of the Afiosemion is rounded, the body is elongated. The color of males is much more interesting and richer than the color of females.
The main color is light brown, which on the back smoothly turns into red-brown, and on the abdomen altogether becomes light blue. A blue-green strip runs along the body from the head to the tail, on which there are small red-brown specks.
There is a reddish brown border around the jaw.
The first rays on the dorsal fin are rather strongly elongated, while the others are more modest in size. On the yellow-gray dorsal fin there are similar specks. The abdominal and pectoral fins are rounded with red strokes.
Anal fin has elongated first rays. The base is wide, which is closer to the tail begins to taper. The color of the base of the anal fin is yellow-gray with orange edges.
The tail fin is lyre-shaped with the same yellow-gray base and a scattering of small maroon specks. Bottom passes maroon strip.
To spawn, you can set aside fish that have reached a length of 5 centimeters. As a spawning tank, you can use a glass tank with a volume of 5 to 10 liters, at the bottom of which you need to lay a thin layer of peat.
The water in the spawning tank should preferably be old, have a slightly acid reaction, low rigidity (not more than 6 degrees) and a temperature of 24 – 27 degrees.
The diameter of the eggs is 1 – 1.5 millimeters. The male with his tail stirs up peat from the bottom, which will then settle and spawn.
The spawning process can take up to 14 days. During the day, the fish can spawn several times a day, and the female can lay no more than 50 eggs. At the end of the spawning period, producers need to be removed from the spawning aquarium, the substrate with caviar is taken out and gently wrung out, and then packaged and placed in a shaded place for 10 weeks with access to fresh air.
The ambient temperature must be between 19 and 21 degrees. At this time, it is very important to keep the peat moisture level under control and regularly check whether mold has appeared on it.
Upon completion of the diapause, the substrate with caviar is placed in an aquarium with soft (possibly distilled) water, the temperature of which should be between 24 and 26 degrees. First, the peat you have will emerge to the surface, and then, when it is saturated with water, it will sink to the bottom again.
After some time, the young will begin to appear from the substrate, which will immediately begin to swim in the aquarium in search of food.
To youngsters do not die of hunger, you will have to immediately consider what to feed the fry. The most ideal and safest option is the Cyclops nauplii, but remember, in no case do not allow overeating, as it will be fatal for fry. Small things grow extremely quickly and at the age of several weeks their length can be a couple of centimeters and fish can be distinguished by gender.
When a length of 5-6 centimeters is reached, the afiosemion becomes sexually mature. In aquarian conditions, a hydrobiont can live no more than three years, and after a year of life the fish cease to spawn. If there is a shortage of food, then there are cases of cannibalism and predation.
With adequate feeding and maintenance, they get along very well in a common jar with other fish of the same size.
This carpsub family was first found on the territory of the Congo in tropical rain forests. The maximum length of males does not exceed 4 centimeter mark.
The male’s back is colored brown, the sides have a blue reflux. On the head there are three red stripes that smoothly pass into rows of points that run along the whole body of the fish. The dorsal fin is yellow with a red stripe near the base and a red-brown border around the edge.
Anal fin is decorated with vertical blue, orange and red stripes.
The tail fin has a peculiar color, thanks to which the fish got its name. Between the rays of the caudal fin are red stripes, and in the center of the tail there is a red-brown vertical belt, and at the edges of the caudal fin has an orange edging. Pectoral fins are transparent with a light blue tint.
The abdominal fins near the base are blue, and light orange becomes closer to the edge. Females have darker back and light belly. On the sides there are red-brown spots.
I would like to note one feature: in old males, the coloring will gradually turn pale and acquire the color of the females.
The following habitat conditions are characteristic of the Afiosemion stripetail habitats:
- Water temperature – 18 degrees;
- Ambient temperature – 19 degrees;
- Active reaction environment: 6.0 – 6.5 pH.
- Incubation of caviar takes place at a temperature of 16 – 21 degrees.
To keep a pair of fish enough for a 20-liter aquarium with soft water and a thin layer of peat at the bottom of the can. It is advisable to organize a weak aeration and easy flow of water.
From aquarium plants, you can use Thai fern bushes floating in the water column and Javanese moss, which will serve as shelter for aquarium fish. You also have to regularly replace about half the volume of water to fresh.
For spawning are selected producers aged 8 months. If a couple of parents are well prepared for spawning, then when they are planted in a spawn with good conditions, they begin to multiply with great hunts.
Spawning proceeds to a vertical plane near the bottom of the aquarium. As a rule, the substrate for spawning is one of the walls of the aquarium, the side of the stone and other aquarium attributes.
Under good conditions, the female can sweep up to 10 eggs in one day. Of course, the caviar will die partially, but half of it will remain.
To increase the number of live caviar, it is better to collect it every evening in a separate container with disinfected aquarium water with the same chemical parameters as in the spawning tank.
Active spawning is observed only a few days, and its activity depends on atmospheric pressure and weather. After a few days of active spawning in the fish, there will be a slight lull, during which the daily portion of caviar will be only a couple of pieces.
In total, for the entire spawning period, the number of eggs can reach up to 250 pieces.
This representative of the karzubykh is well known to aquarists and in nature it is found in a 30-kilometer zone near Lagos (Nigeria). The males are painted in light yellow tones, the back is green, the belly is light purple. Throughout the body and head there is a scattering of purple spots that merge places in lines.
Near the caudal fin, the color of these strips becomes chestnut. Dorsal fin blue with chestnut spots.
The anal fin is blue, with a horizontal line of chestnut color at the base of it.
The color of the female is rather inconspicuous, the body is light brown, the iris of the eye is golden brown, and on the fins and body there are dark brown strokes. The fins have a narrow light edge. Males can grow up to 5 centimeters in length, females – 3.5 – 4.5 centimeters.
Depending on the size of the fish, the aquarist is determined with the conditions for their maintenance. The best option is to engage in breeding of Icay’s Afiosemion in a 30-liter jar.
Often males can organize fights with each other, which end with just torn fins.
Afiosemion refers to an intermediate link, which is located between the perennial and one-year of the Afiosemion. Mature fish becomes at the age of 2-3 months. Spawning proceeds both on the plants and on the peat laid on the bottom of the aquarium.
If the female sprays eggs on peat, then there will be more chances to get numerous offspring. The reason is that the eggs laid on the peat, you can collect and pour all of the at the same time, while on plants it will develop from the moment of spawning and the larvae will hatch at different times. To reduce the loss of offspring, the aquarist will have to acquire a huge number of aquariums, where more adult individuals will need to be deposited.
The fact is that rapidly growing fry of afiosemionov can manifest cannibalism in relation to their fellows.
To get as much caviar in the peat, you need two manufacturers to plant in a separate container with a volume of 5 to 20 liters with a large bottom area. The water level in this case must be made 3 – 6 centimeters.
The spawning process takes from 7 to 14 days, at the end of which the substrate with caviar is removed from the aquarium, dried and placed in a plastic bag for long-term storage. For 10 to 12 weeks, the caviar substrate will be stored for you, after which it is necessary to place the substrate in a container with distilled or distilled tap water, the temperature of which should be about 17 degrees.
Fry begin to hatch out after a couple of hours. Two days later, the peat with caviar must be removed again from the aquarium and dried again. Then the procedure will have to be repeated in a few weeks.
There have been cases when aquarists have performed this procedure several times. The newly emerged fry should immediately begin to feed well with plankton.
If you delay with feeding, more than half of the young can die.
Afiosemion belongs to the group of tooth-toothed, which can not boast of its size. This fish occurs quite often in Africa, where it is constantly humid. As a rule, practically all representatives of this subgroup develop caviar either in very wet soil or directly in water.
The maximum length of males is 5 centimeters, samochek – 4 centimeters.
The body of the fish is rather slender, the back of the males is painted in a brown-green shade, the sides are light. Over the entire length of the body of the fish there are red dots and strokes. The closer to the back, the clearly expressed longitudinal strip formed by these same points.
This strip runs from the tail base to the very back of the fish. The pectoral fins are colorless, and all the others are blue-green. There is a horizontal red stripe on the ventral fins.
The anal and dorsal fins are pointed.
These peaceful and calm aquarium fish can be safely contained in a species jar or with other tooth-teeth of the same size. Surprisingly, the males are not satisfied with each other skirmishes and live quite peacefully with each other. The light in the aquarium should be moderate, the water should have a weak acid reaction and medium hardness.
When an aquarist keeps these fish there may be certain difficulties in feeding.
The fact is that under natural conditions, Lambert’s cosio-seasonion feeds mainly on small insects and their larvae, which fall into the water. The most common food of this fish – ants and their larvae. But in aquarium conditions it is best to give preference to live food, for example, cyclops, tubers and daphnia (only not dried).
With great enthusiasm, the overseasom eats small insects, fruit flies and various small larvae.
To dilute this hydrobiont is enough a two-liter jar, which is filled in half with water, the chemical parameters of which should be the following:
- Stiffness: 1 – 2 degrees;
- Active reaction environment: 6.0 – 6.3 pH;
- Water temperature: 22 – 25 degrees.
To one male, 3-4 females can be hooked into the jar, because the fish have poor fertility. During the day one female can give only a couple of eggs, and sometimes not give anything at all. As a substrate for spawning is best to use fibrous peat.
Caviar is left both in wet peat and directly in water. But, if you leave the eggs in the water, then the period of its development at a water temperature of 22 – 25 degrees will be reduced by about a third.
If you leave the eggs in wet peat, the ripening period can last up to 35 days. After hatching of the larvae, they swim with the yolk resorbable sac for another day.
Fry will gather near the surface of the water and will immediately seek shelter in the substrate when frightened. Growth of fry is rather slow; in the first period of their life, the young should be fed with nauplii of Artemia and Cyclops.
Even with good feeding, the length of the fry by the month of life does not exceed 1 centimeter. Collect fry begin to three months of life, and by the age of 10 months become sexually mature.
But there is one advantage, in comparison with other tooth-toothed ones, this afiosemion lives long enough – up to 2.5 years.
That’s all I have, I hope, the article was interesting and informative.
