Even with all the hardiness of this fish and its ability to use atmospheric oxygen, one should not underestimate the importance of maintaining high water quality. It is recommended to renew a quarter of the aquarium's volume weekly. During routine aquarium cleaning, it is advisable to leave the back wall untouched so that algae, serving as an additional food source, can remain on it. Special attention should be paid to filtration: the filter should be powerful enough, but at the same time, it should not create a strong current, as these fish prefer calm, still waters. The presence of a lid on the aquarium allows for the formation of a layer of humid air above the surface, the temperature of which will be higher than room temperature. This minimizes temperature shock when the fish gulps atmospheric air and reduces the risk of damage to the labyrinth organ. When decorating the aquarium, provide several shelters using natural or artificial elements such as snags, grottoes, imitations of sunken ships, or castles. Any substrate can be used, but dark shades will help enhance the fish's coloration; bright substrates (yellow, red, blue, and others) are not recommended. Plants should be grouped, with a preference for species with stiff leaves or artificial analogs. Floating plants are allowed, provided they do not hinder the fish's access to the water surface.
