Hello dear aquarists. Today I want to talk with you about another labyrinth representative.
Lunar gourami in nature lives in ponds densely overgrown with grass. The homeland of this representative of the labyrinth family is Southeast Asia, and in particular Thailand and Cambodia.
For the first time this fish was brought to the territory of Europe in the distant 1951.
The lunar gourami has a tall body, which is slightly flattened laterally and elongated. The mouth is small, the eyes are decent. Unlike other types of guramocs, the back of the lunar guramka fin is significantly shorter and has a more rounded shape.
The scales are uniform, has a bluish tint and shimmers in the light. The female is not as slim as a male and with its back fin it is more elongated and pointed.
The ventral fins of the female are colored orange. During spawning, the breast in males becomes yellowish-red.
Under natural conditions, the lunar gourami can grow up to 20 centimeters, but in conditions of bondage it is rare when it exceeds the 15-centimeter mark.
Lunar guramka refers to a peaceful and rather shy aquarium fish, which, if a danger is detected, are immediately hidden in the vegetation. It is possible to contain this representative of the labyrinths with both small fish and large ones, although there were still cases when an adult individual of the lunar guramka offended Lyalius and labiosis. Fish mostly prefers to stay in the middle and upper layers of water.
Leads daytime life and all his free time is engaged in cleaning aquarium plants from various fouling.
When selecting an aquarium for this gourami, it is necessary to adhere to the proportion: for 4 adults – 100 liters of water. An obligatory condition in an aquarium with gourami is dense vegetation, which is best achieved with long-stem trees (Bacopa, Ludwigia, Vallisneria, Elodea, Rogovistnik, Ambulia).
Do not forget the same about the other elements of the decor (stones, snags and so on). But at the same time, it is very important to leave enough space for the fish to swim around the aquarium and light the jar well.
Aquarium soil is preferable to dark color.
The process of breathing fish is carried out with the help of a special body-labyrinth, which releases oxygen from atmospheric air. Do not forget to cover the jar with a cover glass, since all your inhabitants can jump out of the aquarium.
And besides, the cover glass will create a kind of greenhouse effect over the surface of the water and warm air from the lamp will stay there. And this is very important for gourami, if you do not want them to catch a cold.
The parameters of water in the aquarium with lunar gouras should be approximately as follows:
- water hardness: 5-20 °;
- active reaction medium (pH): 6.0-7.5;
- water temperature: 24-26 ° C.
Be sure to replace every week up to 30% of water to fresh. Just do not forget about the filtration and aeration of the aquarium.
You can feed the guramka with any kind of food, starting with live food and ending with all kinds of substitutes. Since the fish is a modest nurse of the aquarium, do not forget to feed it sometimes with dry food of plant origin.
Just do not let the fish overeat, it is better underfed than overfeeding.
The lunar gourami reproduces from the six months of age, this is precisely the time of its puberty. The spawning process is carried out in banks of about 100 liters or more.
Required in a spawning aquarium presence of the substrate. Throw in the aquarium for spawning small-leaved plants that will stay near the surface.
They are later used by the male in preparing the nest.
It is advisable to cover the viewing wall of the aquarium so that the fish are not scared. Water in spawning should have the following parameters:
- water hardness: 4-10 °;
- active reaction medium (pH): 6.0-7.0;
- water temperature: 26 – 30 ° С.
Make the water level in spawning a little more than 10 centimeters. In order to propagate the lunar guramok, aquarists select one male and a pair of females.
Ideally, of course, to plant a whole group of fish to spawn, this is for sure, since not every male is able to fertilize all the eggs. Before breeding, producers should be kept separately for two weeks and actively fed.
After that, the male is placed in a spawning aquarium and he proceeds to the construction of a nest for eggs.
The nest is about 25 centimeters in diameter and about 15 centimeters high. As soon as the nest is ready, the manufacturers will start the marriage games.
The male envelops the female, and at about three o’clock in portions, he spawns in the prepared nest. The number of eggs depends on the size of the female, and can vary from 100 to 5000 eggs.
After spawning, the female is removed from the spawning ground and the male remains on his own to keep order in the aquarium with the children.
Dead and unfertilized eggs male neatly removes from the nest. Somewhere in three days the fry will begin to swim and eat independently.
After this, it is advisable to remove the male from the spawn so that he does not eat all the offspring and cut in a weak aeration.
Gradually, the water level in spawning is lowered to 7 centimeters and kept so until teenagers do not form a labyrinth organ. Small things can be fed rotifers, ciliates, egg yolk.
Once a week it is necessary to substitute up to 50% of water. Somewhere in a week, you can add the first plants (fern and cabomb) to the jar.
They need to be planted in the ground and press down with a load. Why exactly these plants?
It’s simple – they clean the aquarium water. Watch for the development of young stock, as it rarely develops evenly. There may be cases of dominance of some individuals over others.
In this case, the fish need to be transplanted from each other.
