I just wrote about the foot detox being a scam. I am not sure if a fish pedicure is a scam, but it is certainly not for the fainted hearted!
Fish pedicure salons are popping up all over the place, especially Europe (and being closed down due to infection control concerns). The idea behind it is that the foot is placed into a container of water and a particular breed of fish eat the dead dry skin and leave the normal skin alone. The testimonials are that people love it, but I am going to sear clear of it.
