Usually inhabitants of an aquarium are bright, beautiful, graceful, but always very silent creatures. Although there is a variety of fish that can fill the apartment with unusual sounds. Grumbling gourami - a small and very original exception. Of course, they are not parrots, and endless chirping is not published. Yes, and their grumbling itself is more like a quiet croaking of frogs or a quiet chirping. But the very ability of a wordless creature to surprise others with its "chirping" makes it a potential candidate for any worthwhile collection of aquarium fish .

The length of our grumblers does not exceed 7.5 cm, so for a couple of gurami enough for a full tank of 30 liters. But all the same it is better to have a flock of up to 10 individuals, diluting it with representatives of other species of aquatic inhabitants. It is necessary to know that these fish know how to absorb atmospheric air, using a peculiar labyrinthine organ. At one time there was an opinion that it was they who were making their own chirping sounds, but then another answer was received - grumbling is created with the help of the tendons of the pectoral fin by the principle of guitar strings.
Taking care of these ghouls is not a difficult task. Inhabitants of lakes, large ditches and rice fields like thickets, so it is best to fill the aquarium with plants and provide it with not very bright light. The water temperature should be about 22-25 °, the pH within 6-7.5. Filtering and aeration should not cause a strong current, otherwise gurus will not create nests. Change the water (up to 10-20%) a couple times a month.
What fish get along with the gurus?
Our grumblers belong to micro-predators, consuming with pleasure, like larvae, insects, crustaceans, fruit flies, and small shrimps. In addition, these fish eat frozen and dry food, which facilitates their maintenance. Sexual maturity of females of these gouramis reach to six months of age, but males need twice as much time for this. In appearance, the female is a bit pale and slender than the partners. Sometimes "guys" arrange scuffles, but they do not cause any damage to the opponents.
