The red garra (Garra rufa), also known as the doctor fish or nibble fish, is a species of cyprinid that is native to a wide range of freshwater habitats in subtropical parts of 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]

Distribution, habitat and taxonomy

As traditionally defined, Garra rufa is native to Turkey, Syria, Jordan, Israel, Palestine, Iraq and Iran. [1] Some of the main systems where it is found are the Kızıl, Seyhan, Ceyhan, Orontes, Queiq, Jordan, Tigris–Euphrates, Kor, and Mond river basins, but the species also inhabits other coastal river basins in the Levant and Iran, as well as the endorheic 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 taxonomy of this species has been labelled with uncertainty. As traditionally defined ( sensu lato ), there are some morphological variations over its relatively large range and it has been recognized for several years that it likely was a species complex. [5] [6] Several subspecies have been described, but their validity is questionable and in the last few decades authorities have generally not recognized them. Nevertheless, reviews published since 2014 have provided genetic and morphologic evidence for recognizing some of them as separate species, while other new species have been described from the species complex. This includes G. turcica (formerly a subspecies) from its Turkish range, except the Tigris–Euphrates system, G. jordanica (new species) from the northern Dead Sea basin, including the Jordan River, in Israel, Jordan and Syria, G. gymnothorax (formerly a subspecies) from 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. [7] [8] [9]

Other members of the G. rufa complex are G. barreimiae , G. elegans , G. ghorensis , G. longipinnis , G. nana , G. persica , G. rossica and G. sahilia , but these were generally recognized as valid species many years ago. [7] [8] [9] Finally the complex includes four cavefish: G. lorestanensis , G. tashanensis , G. typhlops and G. widdowsoni . [8]

Doctor fish facilities at spa resorts exist in many countries worldwide. In 2006, doctor fish spa resorts opened in Kangal, Turkey, Hakone, Japan, and Umag, Croatia, where the fish are used to clean the bathers at the spa.[ citation needed ] In 2008, two widely known doctor fish pedicure services were opened in the United States in Fairfax County, Virginia, [10] and 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] [11] [12] In 2011, the UK Health Protection Agency issued a report assigning a "very low" risk of transferring infection from the procedure. [13]

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". [12] The procedure is legal in Quebec, with a few clinics in Montreal. [14] 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. [15]

Garra rufa seen in the spa and aquarium trade mostly originate from commercial facilities in Israel and to a lesser degree Turkey. [6] Since Israeli and many (but not all) Turkish populations of "G. rufa" now are recognized as G. jordanica and G. turcica instead, this leads to questions over the true identity of most of the fish seen in the trade. [7] [9] [16] It is legally protected from capture from the wild in Turkey due to concerns of overharvesting. Despite its ability to survive in polluted waters, [1] the species requires clean, well-oxygenated and moving waters to thrive in an aquarium. [6] 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 ]

When used as a prelude intended to enhance the effects of ultraviolet light expoure in psoriasis treatment, fish pedicure is known as ichthyotherapy. [17]

Capoeta, also known as scrapers, is a genus of fish in the family Cyprinidae found in Western Asia. The distribution extends from Turkey to the Levant, to Transcaucasia, Iraq, Turkmenistan, in Armenia, particularly in lake Sevan and northern Afghanistan. This genus is most closely related to Luciobarbus and in itself is divided into three morphologically, biogeographically and genetically distinct groups or clades: the Mesopotamian clade, the Anatolian-Iranian clade and the Aralo-Caspian clade. The Mesopotamian clade was split off to Paracapoeta in 2022.

Similar spiny loaches, occurring generally south of the range of Cobitis, are nowadays separated in Sabanejewia.

<i>Garra</i> Genus of fishes

Garra is a genus of fish in the family Cyprinidae. These fish are one example of the "log suckers", sucker-mouthed barbs and other cyprinids commonly kept in aquaria to keep down algae. The doctor fish of Anatolia and the Middle East belongs in this genus. The majority of the more than 160 species of garras are native to Asia, but about one-fifth of the species are from Africa.

Garra typhlops, also known as the Iran cave barb is a species of ray-finned fish in the family Cyprinidae. It is endemic to caves in Iran. Like other cave-adapted fish, it is blind and lacks pigmentation.

Eidinemacheilus smithi, also known as the Zagroz blind loach, is a species of loach in the family Nemacheilidae. This cavefish is endemic to an aquifer in the Karun River drainage in the Zagros Mountains of Iran.

Garra widdowsoni, commonly known as the Iraq blind barb or Haditha cave garra, is a species of cyprinid fish endemic to underground water systems near Haditha in Iraq. Although traditionally placed in its own genus Typhlogarra, this is not supported by genetic evidence, leading to its move to genus Garra. This cavefish is considered critically endangered because of water extraction, which has lowered the groundwater level. Once abundant, a survey in 2012 found that it now was very rare. Another species from the same place, Caecocypris basimi, may already be extinct. The only other known cavefish in Iraq is Eidinemacheilus proudlovei.

The Mesopotamian barbel or leopard barbel is a species of cyprinid fish found in the Tigris-Euphrates river system and is an inhabitant of large rivers. It has been declining very rapidly for at least the last 30 years. This species has disappeared for 12 years until it was rediscovered in January 2024 after a local fisherman caught an individual, and soon after another individual was captured. While there are not enough data to identify the actual rate of population decline, it was once locally abundant but now almost absent.

Garra lorestanensis is a species of ray-finned fish in the genus Garra Known from the Loven Cave, the natural outlet of a subterranean limestone system of the Zagros Mountains in the Ab-e Sirum or Ab-e Serum Valley near Tang-e Haft railway station, the Tigris River drainage, the Persian Gulf Basin, Lorestan Province, southwestern Iran.

Garra jordanica is a species of ray-finned fish in the family Cyprinidae. This small fish, up to 10 cm (4 in) in standard length, is found in the northern Dead Sea basin, including the Jordan River system and Lake Kinneret, in Israel, Jordan and Syria. Populations in the coastal rivers of Kishon, Daliyya, and Taninnim have not been studied in detail, but may also be this species. In the past all these populations were included in G. rufa. Since the "G. rufa" seen in the aquarium and spa trade mostly are of Israeli origin, this leads to questions over their true identity. In the southern Dead Sea basin G. jordanica is replaced by the much rarer G. ghorensis.
