They call it doctor fish cause they feed on the skin of human. They eat DEAD cells. Great. Haha. I’m really really interested with this. I want to know a lot of things about this doctor fishes. Hmmm.. this could be a good research thing in the future. But the big question is, are these fishes available in the Philippines? I want to grow some of these fishes. They seems to be very useful. According to this article in a Chinese newspaper, beauty-seekers in Southern China (and other parts of the world) are soaking themselves in pools filled with a type of small fish that eat human skin: Garra Rufa, a type of small tropical fish, also nicknamed Chinchin Yu, nibble fish or simply doctor fish, are put in hot springs. As they can live and swim freely in at least 43-degree-hot waters, they are naturally used for the treatment of skin diseases in such spas. When placed in the spa, these fish can feed themselves on the dead cells of the human body, since they only consume such cells, leaving the healthy skin of the human body to grow. The whole process is reportedly free of pain. It won’t hurt and the bather might feel a pleasant tingling on his or her skin.
