Breeding barbs (breeding) at home: spawning, the differences of the female from the male, pregnancy, in general, and a separate aquarium, fry (growing, feeding)

Breeding barbs at home occurs constantly. In the general aquarium, caviar and fry are eaten.

To preserve the offspring of the producers are deposited. Breeding barbs with a size of 15 cm (hard-lipped, red-tailed, bream-like, Hipsibarbus) outside nurseries require large capacities.

Reproduction consider the example of barbat Sumatransky.

The aquarium fish barbus Sumatran (Puntigrus tetrazona) is found in the natural standing and flowing waters of Sumatra, Borneo, and Kalimantan (Indonesia). Appeared in the USSR after World War II. The body is elliptical, compressed laterally.

The color is golden, with 4 vertical black stripes, the scales glistens. The fins are transparent, with a reddish tinge. Grow up to 6-7 cm.

In aquariums reproduces actively under the conditions of detention.

  • Medium temperature: 21–25 ° C. Barbus can withstand a drop of up to 15 ° C, but there will be no intense coloring, interesting behavior and reproduction.
  • Acidity: pH 6-7.
  • Stiffness: 1–5 ° W.

Weekly substitution of 1 / 4–1 / 3 of water in the vessel. Mandatory filtering, air purge desirable.

3-4 years live in captivity.

Sexual dimorphism is weak. It is impossible to determine the sex of a barb to sexual maturity. The female can be distinguished by a larger size (5–7 mm in length) and an enlarged abdomen.

The coloring of the male is distinguished by contrast, the jaws are intensely orange.

The rear edge of the female’s anal fin is inclined relative to the base of the tail at 60–90 °. The male is 30–45 °.

Isolate males from females for 1-2 weeks, but do not tighten. Overexposed males fight. Opportunities for tagging females get sick.

Preparing to breed barbs feed live or frozen food. 1/3 of the diet – oatmeal (Hercules), tablets with spirulina.

The day before spawning – fasting day.

Ready-to-spawn males are aggressive. The pregnancy of the female is determined by the swollen abdomen and the swollen anus.

In the above photo – female suitable for spawning.

Start by selecting manufacturers. Choose barbs of the usual sizes.

Unacceptable defects in body structure and color.

Spawning barbs stimulate the addition of soft water, increasing the temperature by a couple of degrees. A pregnant female moves actively, the male follows her, patting the sides and knocking out her calf.

Eggs rush into the water column, where they are fertilized by a male.

Spawning aquarium – 10-15 liters per couple. A column of water – 15–20 cm.

Suitable vessel type “trough”. Plants that float in the water column (rodentard, monosolenium, Javanese moss) will help the female to periodically rest from the annoying male and will be useful for the young.

Prepare water at the rate of: 2/3 of the aquarium and 1/3 of the spawning replenish with fresh sedimented or osmosis (recommended). Maintain a temperature of 28 ° C.

Aeration, filter and lighting until the appearance of caviar is required.

The bottom of the spawning banks covered with mesh-separator. A significant part of the eggs after spawning will pass through the lattice and will not be eaten by parents.

The rest is stuck to the grid and plants.

Spawning usually begins immediately after disembarking a selected pair. The label occurs at night and ends in the morning, unless artificial darkening is applied.

If it is impossible to use a separator, then cover the bottom with mosses and ferns. Eggs entangled in the green after spawning will be safe.

Soil in the form of large glass balls will protect the failed eggs. The part will stick to the surface and in danger.

The advantage of using mesh:

  • most of the caviar remains;
  • the ability to remove unfertilized eggs;
  • ability to quantify the label.

Most of the roe barbs and fry will be eaten. Manufacturers do not protect offspring. The chances of surviving caviar and fry increase in herbalists with an abundance of ground cover plants (echinodorus), ferns and moss at the bottom.

The appliance should be provided with food, “living dust”. The only advantage is that strong and fast individuals with a good response survive.

Watch out for pregnant barbs. Unscarred caviar leads to the growth of cysts and the death of the fish.

Barbus lays up to 800 eggs. In the first spawning – significantly less.

Larvae bring 60–90%.

Fry hatch within 24-30 hours. After 3-4 days, they begin to move and eat.

Begin to reduce the temperature at 1 ° C per week to the temperature of the general aquarium. Gradually bring the water level to normal.

Turn on the lights. Luminous flux: 30-50 lumens per 1 liter capacity.

Fluorescent and LED lamps with a color temperature of 7000 K are preferred. If the backlight is excessive, place the plants floating on the surface (Riccia, salvinia). Substitute 2–3 times a week water for 1 / 4–1 / 3.

After 2-3 weeks, they begin to acquire color. A month later, the adult barb color is formed. Body length – 1 cm.

Enable filtering. Do not overcrowding. Count on 0.5 lira per fish.

Reach 2 cm individuals send to the general bank. Water change – weekly.

Sexual maturity comes in 6-10 months. Females mature a couple of months earlier than males, which is not typical for fish.

Using a siphon, remove leftovers and feces. Clusters of organics emit ammonia, the high content of which threatens the fish with poisoning.

Starter feed – “live dust”, nauplii, infusoria and microherms. Live food – a balanced diet for growth and the formation of the skeleton barbus. Grow them yourself, organisms caught in natural waters are potentially dangerous.

Feed them with boiled yolk of chicken egg sifted through a net.

Plant food – zooplankton. Put a jar of water in a warm place in the sun.

In 3-4 days Wednesday will bloom. Using a syringe add barbs.

Chopped oat flakes will do.

As you grow, increase the size of the food. Add Artemia, Daphnia. The shallow tubule is separated from the ordinary.

Washed lump in a jar. Fill the vessel with cold water. Large worms will drown.

Drain with small individuals. Repeat the procedure several times.

Do not feed barbs with one type of feed. For dynamic growth and intense color you need variety.

Feed 4 times a day. In two months, go to three meals a day and enter the fasting day.

The reproduction of the barbat of Sumatran is feasible for beginners to aquarists. It is enough to follow simple recommendations.

  • Soft water up to 5 ° W.
  • Neutral or weakly acidic medium.
  • Balanced nutrition with a minimum of dry food.
  • Stable temperature conditions.
  • Clean water with aeration and filtration.

It is impossible to breed in the general aquarium. Defenseless roe and fry become prey for adults.

It is better to get offspring in spawning. Spawning is stimulated by temporary separation and changes in environmental parameters.

It is a little work, and the school of 6–8 individuals will turn into a full-fledged barbnik.
