The doctor fish (Garra rufa) is a cyprinid from the eastern Mediterranean and Middle East, from Turkey and Israel to the Tigris-Euphrates in Iran. Fish sold as G. rufa are marketed worldwide for their questionable ability to remove dead skin, but the species likely represents a complex of closely-related taxa and it is unclear which the traded fish are. Strictly not a tropical species, it is kept at 14-20 °C.
