Labo breeding: the subtleties of the procedure and key points

Agree, a flock of green labo able to decorate almost any species aquarium. Among thickets of plants and heaps of stones, brisk fish with reddish fins stand out in particular.

In nature, these fish live in the northern regions of Thailand, where they are caught in clean and warm brooks and the upper reaches of the Menam River. If you believe the information of various authors, in the habitat chemical parameters of water vary in wide ranges:

  • Water hardness from 3 to 12 degrees;
  • Active reaction environment 6.5 – 7.8 pH;

This feature allowed the fish to be very plastic in terms of conditions.

The main forage for labo is algae of various kinds on the rocks, snags and aquatic vegetation. Thanks to a pair of antennae, the small fish probe the substrate in search of tiny animals and algae. Due to the structure of the oral apparatus and the mouth-grater, the fish perfectly scrapes the algae from the stones.

In addition, Labo excellently eat small crustaceans, insects and mosquito larvae.

For the first time, green laboos appeared in our aquariums in 1981, which were artificially bred at fish farms in Thailand. These fishes have been successfully transported to pet stores all over the world for more than a decade, and the demand for aquatic organisms continues unabated.

From the green fellow albino forms differ in red eye color lemon-yellow body color. Some aquarists are convinced that the combination of red and yellow colors of albinos looks much more impressive than the original form of the fish.

For a long time, it was thought that to breed danios was a very difficult and sometimes impossible task. The first success was recorded when gonadotropic injections were used as a stimulant for spawning.

Even taking into account the fact that every aquarist can handle a syringe perfectly, not everyone can dissolve a labo. And there are several reasons, but this is not the most important thing, the fact is that not every aquarist is able to properly grow fish-producers.

A group of young individuals that are planned for breeding should have at least 15 fish. In order for hydrobionts to grow and develop normally, a large number of algal fouling must be present in the aquarium.

Due to the lack of algae, fish can often conflict with each other, only these skirmishes do not cause any harm to the fish.

If one of the future producers lags behind in development, the rest of the fish immediately begin to spread rot to the congener, driving him to the farthest corner of the aquarium, not giving access to feed. Accordingly, in order to avoid skirmishes, an aquarium for a two-colored labe must be large in volume with many different shelters in the form of heaps of snags, stones and thickets of aquarium plants.

Fish must be placed in an aquarium at the rate of 10 liters of water per 5-centimeter fish. For larger hydrobionts, this proportion should be slightly higher.

Labo without a problem can get along with almost any peaceful fish, the main thing is that the conditions of detention and the hydrochemical parameters of the water fit all hydrobionts. Hydrochemical indicators of water can vary within the following limits:

  • Water hardness 5 – 18 degrees;
  • Active reaction environment 6.8 – 8.0 pH;
  • Water temperature 24 – 30 degrees.

The water in the aquarium should be replaced, even taking into account the powerful filtration, because for normal development the fish need microelements contained in fresh water. Feed the fish with small crustaceans and bloodworms need at least twice a day.

But albinos should be grown separately from their green counterparts, since at a younger age they have less competitiveness. Later, when the fish grow up, they can be kept in the same aquarium.

As the fish grows, they have to be sorted out and discarded the retarded individuals. However, on reaching 9 months of age, lagging fish can be transplanted into another aquarium. In the absence of larger relatives, these fish can catch up with our fellows and become full-fledged producers.

If the necessary feeding and housing conditions are observed, you will be able to have a full-fledged Labo family in a year.

The fish reach sexual maturity at the age of one year with a length of 12-15 centimeters and a weight of 13-15 grams. You must know the weight without fail, since the dosage of gonadotropic preparations is calculated based on the weight of the fish.

Unfortunately, the fish do not have any pronounced sex differences. The only difference that becomes noticeable before spawning is a more rounded abdomen in females when filled with caviar, through which the eggs shine through.

When you determine the sex of fish, females and males need to be seated in different aquariums and continue to be kept separate. Before spawning, producers need to feed hard, especially for females, and often replace the water in the aquarium.

As a spawn you need to use an aquarium with a volume of 150 liters. Water in spawning should be the following parameters:

  • Water hardness 2.5 dGH;
  • Active reaction 6.8 – 7.2 pH;
  • The water temperature is 27 degrees Celsius.

Unfortunately, Labo is still divorced only with gonadotropic injections. This is because the hydrobiont is a brook fish, and it is impossible to recreate similar conditions in an aquarium, including hydrological changes.

When preparing the producers for spawning, you should take into account that in natural conditions caviar becomes floating and it carries water to the places where there is either a weak current or it is completely absent. In such places a lot of plankton, which the younger fish will eat at first.

Accordingly, the spawning aquarium should be equipped with a powerful filter that will create the flow of water.

Next, the fish must be injected, and at the end of the spawning period, the producers must be removed from the aquarium into a special otsadnik, where levomycetin is added to the water, taking into account the proportion of 5 mg per liter of water. A day after spawning, the fish can be released back into the aquariums in which they were kept before spawning.

When you remove spawned fish from an aquarium, it is necessary to reduce aeration in the spawning area and make sure that the eggs constantly float on the surface. After 8 hours, the air supply must also be reduced, since as a result of the eggs hitting each other, the embryos can begin to hatch ahead of time.

Larvae hatching begins 15 hours after spawning. This is where a filter is needed, because after hatching in aquarium water a large amount of decomposition products appears, polluting the water. After three days, when the larvae begin to crawl on the walls of the aquarium, they need to start giving live dust.

Fry Labo grow very quickly and by the end of the month of life they will reach 3 centimeters in length.

At first, the fry look inconspicuous: on a gray background there is a dark spot near the tail, and the fins are transparent in appearance. Fry laboos acquire their first color at three months of age and with a body length of 5 centimeters, only the black spot does not go anywhere and will decorate the fish before puberty.
