Lalius keeping in the aquarium

На пару взрослых рыбок достаточна емкость 15-20 литров. Химический состав воды для содержания не важен. Но температура не должна снижаться ниже 20 градусов по Цельсию. Поэтому аквариум обязательно надо снабдить обогревателем с терморегулятором.

Дно укрывается грунтом темного оттенка. Темные тона грунта и рыбке больше нравятся, и выглядит она на темном фоне привлекательнее. В углах аквариума желательно устроить заросли мелколиственных растений, в которых пугливый лялиус любит прятаться.

Аквариум желательно накрыть крышкой или стеклом. Это не только предотвратит выпрыгивание самца лялиуса из аквариума, но и убережет от простудных заболеваний рыб, которые дышат атмосферным воздухом, если его температура в комнате понижена. Желательна фильтрация воды, так как рыба любит чистую воду. Освещение – общее яркое, верхнее. Кормить желательно живыми не очень крупными кормами. Можно кормить и сухими кормами. Желательны растительные подкормки (салат, шпинат, водоросли).

Lalius Breeding in the aquarium

Breeding is better in the spring, in April – May, when there are no problems with obtaining live dust. As a spawning aquarium suitable tank for 15 – 20 liters. The water level is about ten centimeters.

The water must be soft. To soften the water, boil it for about ten minutes. In most cases, this is enough. However, it is still advisable to check the hardness of the water using one of the methods available to you. It should be about 4 -6 °dH. Boiled water stands for three days. Before pouring it into the spawning tank it should be 3 – 4 hours to blow air with an aquarium compressor.

In the corners of the aquarium must necessarily be arranged thickets of plants, so that the female had somewhere to hide from aggressive during the spawning period of the male. On the surface of the water should be thrown a bundle of riccia, which the male skillfully uses in the construction of a nest of air bubbles.

Training of producers

Male and female for a week before spawning is desirable to keep separately and during this period feed intensively including vegetable supplements. The temperature in the spawning tank is maintained with a temperature regulator at 23-25 °C. It is desirable in the prepared aquarium first start the female and give her a couple of days to get used to it.

Once in a properly arranged water body, the male starts building a nest. Periodically he chases the female, who hides from him in a thicket of plants. When the nest is ready, the female comes out of the shelter and settles down with the male under the nest. The male wraps his body around the female’s abdomen and squeezes the eggs out of her. The eggs are rich in lipids and therefore do not fall to the bottom, but rise to the surface. Lalius male picks them up with his mouth and places them in the nest.

When to remove the female from the spawning ground

After the end of spawning, the male begins to beat the female and may even kill her. Therefore, as soon as spawning is complete, the female should be removed. Do it carefully, as the male during this period pounces on everything that approaches his nest. So pounced on the net, he can jump out of the aquarium. Therefore, first you need to notice where the female hid and then, covering half of the aquarium glass quickly and carefully fished her out.

The male takes care of the nest himself. He adds air bubbles, removes spoiled eggs, and guards the nest. Incubation lasts about 48 hours. And after another three to four days, the fry swim. Now daddy from the spawning ground should be removed and start feeding the fry infusoria, nauplii crustaceans. In extreme cases, yolk.

The fry grow relatively slowly and unevenly. Therefore, they should be sorted periodically. As they grow, they are transferred to larger feeds. At about 1.5 – 2 months, males have stripes characteristic of adults.
