Nutrition and feeding

In nature, fish, while burying themselves, sift the sand through the gills while looking for insect larvae or small crustaceans. In an aquarium , the best will be a varied diet in the form of high-quality, dry and live foods that sink to the bottom, such as Artemia, Tubifex, Dafnia, Ochotka.


The aquarium should be at least 120 cm long. The most suitable substrate for thorns is the sand in which they eagerly bury themselves. If a different medium is used, they may become stressed and have difficulty eating.

To decorate the tank, you can use twisted roots or wood, which will provide them with shaded hiding places. Not too strong light and a few dry leaves on the bottom will complete the natural effect of the tank. An efficient filter is also necessary, which will oxygenate the water well and ensure its proper circulation. Like many other species that inhabit flowing waters, the silt-eaters are quite sensitive to organic pollutants. Therefore, approximately 30 – 50% weekly water changes are recommended.

As a company, fish living in the upper and middle parts of the water are recommended, such as Razbora , Danio and other carp or tetras.
