Occurrence

Garra rufa occurs in the river basins of the Northern and Central Middle East, mainly in Turkey, Syria, Iraq and Iran. It is legally protected from commercial exploitation in Turkey due to concerns of overharvesting for export. Garra rufa can be kept in an aquarium at home; while not strictly a "beginner's fish", it is quite hardy. For treatment of skin diseases, aquarium specimens are not well suited as the skin-feeding behavior fully manifests only under conditions where the food supply is somewhat scarce and unpredictable.

The misleading information perpetrated by those who utilize Garra rufa in profitable ventures is that the Garra rufa actually eat dead skin but this is not strictly true, the filtration systems of tanks that have been analyzed have been shown to capture the skin.

During their activities of foraging they slough off dead skin. They are simply looking for food which in the wild consists of aufwuchs. In both marine and freshwater environments the algae – particularly green algae and diatoms – make up the dominant component of aufwuchs communities. Small crustaceans, rotifers, and protozoans are also commonly found in fresh water and the sea, but insect larvae, oligochaetes and tardigrades are peculiar to freshwater aufwuchs faunas.
