Scientific name: Garra rufa (Heckel, 1843)
Family: Cyprinidae (Carps)
Size: Up to 14cm/5", according to museum records, but usually around 10cm/4".
Origin: A non-migratory freshwater fish found in rivers through much of Iraq, Israel, Jordan, Turkey and Syria. There are also unconfirmed reports of the species in Oman and Saudi Arabia, but these aren't considered compatible with the distributional range of the species.
Habitat: According to Krupp and Schneider, most Garra rufa are found in small muddy streams, rivers and lakes. However, the fish is also found in hot pools and locals bathe there in an attempt to get the fish to remove scales from their skin caused by a range of dermatological conditions.
Water: Temperatures in the natural habitat are said to range from 15-28�C. In hot pools, the fish is said to live at a temperature around the 37�C mark.
Availability: As far as we are aware, this species of Garra is not available through the aquarium trade in the UK or elsewhere. A number of other Garra species, predominantly those from south Asia, are popular fish with specialist fishkeepers. The genus was covered in the July 2005 issue of Practical Fishkeeping.

In my country, in my housing area, they have alot of these spas where you just put yourself in a tub with the GR fishes inside and they will just approach you and just nibble on your body! How cool? I've been thinking of buying these fishes just to see how they live! Near my home, they sell these skin eaters in the pet store for about 90 cents each (USD)!! (in Malaysia, it's RM 3 each)! Not expensive, not cheap so I'm saving up money to buy 10 of these! I just don't have enough info about these fish...
