Description
The Doctor Fish (Garra rufa), also known as the garra rufa fish, pedicure fish, or fish that eat dead skin, is one of the most fascinating freshwater species in the aquarium and spa world. Famous for their gentle skin-nibbling behavior, these garra fish are both active algae grazers in aquariums and popular “fish eating dead skin” in natural spa treatments. Their peaceful nature, hardiness, and unique interaction with humans have made doctor fish a highly sought-after species worldwide.
Native to the warm rivers and hot springs of the Middle East, particularly Turkey and Syria, garra rufa are small cyprinid fish known for their unusual feeding behavior. In aquariums, they act as excellent algae grazers. In spa environments, they are famously used as pedicure fish, gently cleaning away dead skin cells with their specialized mouths. Their dual role as both aquarium fish and spa fish has earned them global recognition.
Garra rufa fish typically grow to 4–6 inches (10–15 cm) in captivity. They have a slender, torpedo-shaped body, usually gray to brown with a slight reddish tint, giving rise to their nickname “reddish log sucker.” Their sucker-like mouth is designed to graze on algae and biofilm, but in spa environments, it is what allows them to perform their famous dead skin nibbling.
Doctor fish are peaceful, social species that do best in groups of 5 or more. In aquariums, they are active bottom-dwellers and thrive in clean, oxygen-rich water with smooth rocks, driftwood, and live plants for grazing. Ideal tankmates include other peaceful community fish such as Tetras, Rasboras, Danios, Loaches, and Corydoras.
