In the aquarium it needs water at 10–20°C (50–68°F). Prussian carp care at a glanceTemperature10–20°C (50–68°F) BiologyInhabits a wide variety of still water bodies and lowland rivers, usually associated with submerged vegetation or regular flooding. Can strongly tolerate low oxygen concentrations and pollution. Lake dwelling individuals move into river mouths to avoid low oxygen water in winter. Feeding larvae and juveniles occur in high-complexity habitats as reed belts. Feeds on plankton, benthic invertebrates, plant material and detritus. Spawns in shallow, warm shores on submerged vegetation. Able to reproduce from unfertilized eggs (gynogenesis). Life span reaches up to about 10 years. Eastern European or wild form of the goldfish.Source: FishBase, licensed CC BY-NC 4.0.

Clear and definite data on original distribution in Europe are not available due to introduction, confusion with Carassius auratus and complex modes of reproduction. At present, widely distributed and commonly stocked together with Cyprinus carpio which is transported throughout Europe.
