Hello dear readers! Gourami nagging belongs to the labyrinth family and lives in densely grass-covered lakes, streams and ponds of Cambodia, Thailand, Laos, Malaysia and Indonesia. They christened the fish with a grumbler because it makes specific sounds with the help of veins on pectoral fins.
These sounds are like a silent crash.
The body of a grumbling gouram is elongated in length and slightly flattened at the sides. The mouth is small and pointed upwards.
The eyes of the fish are large, the fins on the abdomen are long and filiform. The tail has a rounded shape. The grumbling gouram is painted in a golden brown shade and has a bluish-green tint over the body.
The entire length of the body passes several longitudinal strips of black or brown. Fins have may have purple, red and blue reflux. It is possible to distinguish a male from a female by pale color and thickness of the body.
The coloring of the female is noticeably paler and she is somewhat slimmer. Anal and dorsal fins in males of a pointed form are elongated at the ends.
In aquarium conditions, ghouls grumbling can reach 7 centimeters in length.
By itself, the fish is a schooling one, peace-loving like other labyrinths (lyalius, macropod, pearl gouram, marble gouram, chocolate gouram). This aquatic animal can be easily started up by novice aquarists, since it does not require careful maintenance. Best of all, the fish looks in small aquariums with dense vegetation, among which you need to leave free islets.
The fish is daytime and it gets along excellently with other peaceful fish from other families (swordtails, red neons, thorns, rodostomuses, labo). For Labo gourami grumbling will not compete, as he prefers to stay in the upper and middle layer of water.
The lighting in the aquarium with a guram is necessary to be bright, and the capacity itself does not require much. For one pair of fish, a 30-liter aquarium with ample planting of aquarium plants is enough; you can even diversify with floating plants (pistia, riccia, azolla). Do not forget to decorate aquas with snags, stones and leave places for swimming.
A hydrobiont breathes atmospheric air and periodically rises to the surface to inhale. Therefore, be sure to cover the aquarium with a cover glass and a lid with lighting so that there is warm air above the surface of the water, otherwise your pets will catch a cold.
The water in the aquarium with guramki should have the following parameters:
- hardness in the range of 5-20 °;
- acidity: pH 6.0-7.5;
- temperature: 24-28 degrees;
- mandatory regular replacements up to 30% of the volume;
- filtration and aeration.
Grumbling gourami is an omnivorous fish. Under natural conditions, insects, small crustaceans and zooplankton go to feed.
In aquarium conditions, fish can be fed with good ice cream, dry and live food.
To breed grumbling goura need a spawning aquarium of 15 liters minimum, aquarium soil can not be used. The water level in the spawning should be no more than 15 centimeters.
On the surface, it is desirable to have floating plants that go as a building material in preparing the nest. Cover the sight glass so that the fish do not worry.
Water in spawning should have the following parameters:
- water temperature: 27-30 degrees;
- rigidity: 4-10 degrees;
- acidity: 6-7 pH.
For spawning, it is necessary to select several producers (the best is a group of fish, because not all the male is able to fertilize the eggs) and they are kept apart for two weeks. Caviar nest males build near the surface of the water.
During spawning, the female can sweep from 70 to 180 eggs. At the end of spawning, the female is removed from the aquarium, and the male is left to care for future offspring. The male carefully removes the dead calf and returns back to the nest of restless larvae.
Two days later, the fry begin to swim and feed themselves.
As soon as the larvae turn into fry, dad needs to be removed from the spawn, to include a small aeration. Then the water level must be lowered to 5-10 centimeters, and the water will not change until the young labs have a labyrinth and they do not start to get enough air from the surface.
Feed the fry with infusoria, rotifers and egg yolk. Grumpy grunting become sexually mature at 4-6 months of age.
