| Garra rufa Heckel, 1846 |
The term doctor fish is the name given to two species of fish (Garra rufa, discussed here, and Cyprinion macrostomus). They live and breed in outdoor pools of some Turkish spas, where they feed on the skin of patients with psoriasis. The fish are like combfishes in that they only consume the affected and dead areas of the skin, leaving the healthy skin to grow, with the outdoor location of the treatment beneficial effects. The spas are not meant as a treatment option, only as a temporary cure for symptoms, and patients usually revisit the spas every few months. Some patients have experienced complete cure of psoriasis after repeated treatments, but due to the unpredictable nature of the disease, which is strongly influenced by endogenous factors, this is something that may happen, but not to be usually expected.
The nicknames nibble fish, kangal fish, and doctorfishen are commonly applied to both species of doctor fish. Outside the medical context, Garra rufa is called reddish log sucker.
The species 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.
In 2006, a Doctor Fish spa resort opened in Hakone, Japan. These fish are used to clean the feet of the bathers at the spa.
