The red garra (Garra rufa), also known as the doctor fish or nibble fish, is a

Western Asia.[4] This small fish typically is up to about 14 centimeters (5.5 inches) in total length,[4] but locally individuals can reach as much as 24 cm (9.5 in).[5]

In the wild, Garra rufa feed on detritus, algae and tiny animals (arthropods and other zooplankton).[5] Since the early 21st century, this fish has been integrated into a spa treatment where they feed on the stratum corneum skin layer of patients with psoriasis. While the doctor fish treatment has been found to alleviate the symptoms of psoriasis,[6] the treatment is not curative, and no cure for psoriasis currently exists. The use of the fish as a spa treatment for the wider public is still widely debated on grounds of efficacy and validity.

Distribution, habitat and taxonomy

As traditionally defined, Garra rufa is native to

Lake Maharlu system.[1][4][5] It lives in rivers, streams, canals, reservoirs, ponds and lakes, although it tends to avoid stagnant waters.[1][4] It often is common or abundant, even in areas that are heavily influenced by humans like polluted canals.[1][5]

The

Karun, Balarud and Bashar systems in Iran, G. mondica (new species) of the Mond River basin in Iran, and G. amirhosseini (new species) from the Sartang-e-Bijar Spring in the Tigris River system in Iran. G. jordanica and G. turcica have entirely separate ranges from true G. rufa (thus limiting its range to the Tigris–Euphrates system and river systems in Iran), but the others do overlap in range with true G. rufa or at least occur in the same river basins.[8][9][10]

Other members of the G. rufa complex are

G. widdowsoni.[9]

Doctor fish facilities at spa resorts exist in many countries worldwide. In 2006, doctor fish spa resorts opened in

Milwaukee, Wisconsin. Wisconsin ordered the closure of the doctor fish service shortly after its opening. In 2010, the first spa opened in the United Kingdom in Sheffield.[2][3][12][13] In 2011, the UK Health Protection Agency issued a report assigning a "very low" risk of transferring infection from the procedure.[14]

The practice is banned in several of the states in the United States and Canadian provinces as cosmetology regulators believe the practice is unsanitary, with the

Wall Street Journal saying that "cosmetology regulations generally mandate that tools need to be discarded or sanitized after each use. But epidermis-eating fish are too expensive to throw away".[13] The procedure is legal in Quebec, with a few clinics in Montreal.[15] The animal rights organization People for the Ethical Treatment of Animals (PETA), which opposes all human use of animals, denounces the practice, citing callous methods of international transportation and suggesting that the fish are deliberately starved between treatments to force them to eat an abnormal food.[16]

Garra rufa seen in the spa and

overharvesting. Despite its ability to survive in polluted waters,[1] the species requires clean, well-oxygenated and moving waters to thrive in an aquarium.[7] 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 can be scarce and unpredictable.[citation needed
