Preparation for spawning of tiger barb
In order to prepare calmly for spawning, the future producers are planted two weeks before the start of the process and the males are separated from the females. At this stage, it is important not to overdo the fish. Otherwise, women may have cystic diseases, leading to the death of an individual who cannot mark the tiger barb eggs, and men become overly aggressive.
If you study the preparation of the tiger barb for breeding, you can see that special requirements are placed on the organization of spawning grounds.
For spawning, the tiger barb requires a disinfected glass aquarium with a volume of 10 liters per pair.
An important parameter for active fish is:
- Floor area, not less than 500 sq. cm;
- the water layer is about 25 cm.
The soil is not covered with soil but covered with a fine grid, which is supposed to protect the deposited eggs from consumption by the parents themselves. Not superfluous in the aquarium will be a fern or Java Moss. To hold the eggs of the tiger barbs, which reproduces in the spawning ground, you can attach a few bundles of fishing line or a nylon washcloth to the ground.
Water preparation for breeding Sumatran barbs
To fill the spawning grounds, up to 70% of predetermined water and 30% distilled water are used. But this is not the end of water preparation.
- To increase the acidity, which helps to cope with dangerous infections during the spawning of tiger barb, peat extract, a decoction of oak bark, or alder cones are added to the water.
- If you add water from the aquarium to the spawning grounds, where the breeding of the tiger barb is already completed, will be the effectiveness of the process is higher.
- At the time of launch, the water should have a temperature of 25-28 degrees and be well ventilated. In addition, flushing the spawning grounds with the shooting of fish is immediately stopped.
Active spawning of tiger barb, interspersed with rest periods, lasts 6 to 18 hours. During this time, the male must carefully decant up to 600 eggs from the female during mating games, expressed in contact with the bellies.
Bright light at this time not only does not harm but even helps the process. To increase the attraction of the tiger barb.
- some water from the aquarium, where the fish spawned;
- A decoction of oak bark;
- a drop of caviar egg squeezed out of the female’s belly.
If despite careful selection of tiger barb, breeding is sluggish and there is no result within three days and no eggs, they must replace the male or female depending on the behavior of the fish.
When the activity of the spawning fish has subsided, the egg remains are manually removed from the female’s abdomen by running their fingers to the anal opening. And the tiger barb, whose reproduction was completed by the 2-3-day transfer in a separate aquarium.
In the spawning ground, the water level is lowered and left 10 cm, and after 12 hours, the net released from the spawning is removed from the aquarium.
To prevent the development of a fungus that appears on dead eggs, methylene blue is added to the water. This technique not only helps to improve the environment but also helps to identify unfertilized eggs that turn from transparent to white in a few hours.
Diseases, during the breeding season
Gradually raise the water temperature to usual adult fish level and monitor the health of past spawning tiger barbs.
With food or insufficiently clean water, ectoparasites, and pathogens of dangerous diseases for fish can enter the aquarium.
You should be careful when Barbus:
- is sluggish;
- loses interest in food;
- it is covered with a layer of mucus and the fins stick together.
In this case:
- Barbs left for recovery because;
- Water is tinted with methylene blue ;
- for fish, short-term salt baths are carried out;
- use antibiotics for treatment.
As prophylaxis, a day after the completion of the spawning tiger barbs changed half of the water into distilled and increase ventilation, and also with blueprints adjusted the watercolor to light blue.
After the end of the breeding process of Sumatra barbs, when the producers are removed from the spawning ground:
- one-third of the water in it is replaced;
- dye the contents of the aquarium with methylene blue to prevent the development of a fungal infection
- the aquarium is shaded and protects it from the effects of ultra-violet light, which contributes to the mutation of eggs and the emergence of fry with an unusual color.
The development of tiger barb eggs lasts up to two days, after which larvae appear. After another three days or a little later, the larvae will fry, begin to move actively, and feed on themselves.
So if there are a large number of fry in an aquarium, the boy should sit in separate ten-liter glass containers with a 20-centimeter water layer that is heated to 24°C.
With good care, the fry grows quickly, but since this process is uneven, the young must be sorted so that stronger specimens do not eat small relatives. A month after spawning, the barbs reach centimeters in length. And soon the fry form an adult color and are ready to move to the aquarium for permanent residence.
What to feed the fry?
The first food for barbs is living dust, which can be supplemented or replaced by the yolks of hard-boiled eggs. Actively growing fish requires five times protein feed, which can contain nematodes, infusoria, rotifers, and nauplius.
The main danger for fry are bacteria that develop on food waste and excrement, which is extremely important to regularly remove from the aquarium.
Watching how the breed tiger barb will help the amateur aquarium to gain important experience in breeding and alone replenish the population of your aquarium.
Tiger barb (Barbus tetrazona)
Fish of the genus puntius live in the waters of Africa, South and Southeast Asia. Up to a hundred species of these fish are concentrated in the aquariums of amateur fish farmers. These are representatives of caviar egg spawners, many of them are gregarious, schooling. The aquarium likes old water with a temperature of 20-23°C and tolerates a decrease to 16°C. They are afraid of sudden temperature changes. Mobile, prefer free places for swimming. For representatives of their own and other species, they are peaceful.
The tiger barb is found in the waters of the islands of Kalimantan and Sumatra. It was brought to us in 1947. The body of the fish is a golden yellow, high, compressed from the sides, reaches a size of 7 cm. There are four vertical stripes with a barely noticeable green tint over the body. The upper part of the body is painted in thick brown tones, the lower part is olive white. The fin on the back with a red border, the male-bright. In addition, the male has a red plaque on the front part of the head and nose. The tail fin is also significantly lighter than that of the female. This difference in color intensity can serve as an evaluation of the best specimens of males for selection for spawning.
The tiger barb is a playful and pugnacious fish of its kind. Lives peacefully with other fish. Young fish should be placed in the aquarium for the purpose of adaptation and further selection for spawning. In terms of food, these fish are not picky – they eat both live and dry.
Need to spawn barbs, selected long before the onset of puberty. They are kept separately in the aquarium (for growth) at a temperature of 20-22°C. At this time, fish are fed once a day, but a variety of foods. They are carefully monitored to ensure that they do not become obese. The aquarium should have plants and a good filter. The fourth part of the water is replaced once a week.
Medium-sized, well-developed, colorful six-to eight-month barbs are selected for spawning. At this age, it is easy to identify females with eggs by the swelling in the lower part of the abdomen near the ventral opening. Obese fish with bulges in the upper abdomen, should not be taken. The selected ones are kept separate under the same conditions.
The spawning ground is a one-and-a-half-liter aquarium with a net (dark) that is two centimeters from the ground. As a substrate the Leptochilus pteropus with weight is suitable. Install an air sprayer and side lighting. The water temperature is maintained at 28°C, the hardness is in the range of 6-10°, pH = 6.8.
Manufacturers arrange the spawning of the game close to the roots of the ferns and cling to each other. The female sweeps up to 500 or more eggs. Tiger barb egg is transparent, with a barely perceptible Amber tone, sticky, much of it remains at the roots of the fern.
After spawning, the producers are taken away and the net removed. Fern can be removed by shaking the eggs, but it is better to go until the larvae and fry appear. Larvae hatch in 24 hours. Fry starts swimming on the fourth day. From this point on they are fed with small Daphnia. The water temperature is reduced to 26°C.
With the growth of fry, you get more food. Already at the age of four months, men can be distinguished from women by the bright red color of the tail fins and dorsal fins, the red color of the mouth and the front of the head. Hope you got an answer to your question what do tiger barb eggs look like.
The lifespan of the tetra barb under aquarium conditions is about 3-4 years.
