I saw one of those places last November when I was in Bangkok. It caught my eye as I had seen a news item in the U.S. where some health departments were banning them.

While looking around for the name of those fish, which looks to be Garra Rufa (»ÅÒ¡ÒÃÒÃÙ¿Ò), I found some other interesting information on the same Thai health site. It says those fish are expensive as they have to be imported, which may cause some entrepreneurs to take the cheap route and substitute a different type of fish with sharper teeth, increasing the risk for wounds. So you should verify the species first. They also warn against using the service soon after cutting your toenails or shaving your legs, as even micro cuts are big enough to let in waterborne bacteria. Also, there's a high risk of contracting a kind of Tuberculosis (Çѳâäà·ÕÂÁ), and some bacteria are chlorine resistant.
