Thank you for this long thread, I have read it all with great interest after googling garra rufa fish. I have long wanted to have this done to my feet after seeing bits on Tv about this and today while walking through York down stonegate I was handed a leaflet from a new shop opening , I went in to check it out and it was packed with women with their feet in the tanks and was very excited about going back when I get time, however as I walked away I started to ask myself about the welfare of the fish ( I have been an aquarium and pond keeper for over 20 years, so not sure why this question didnt enter my head immediately really!) I was worried about the filters and how often water was changed etc etc and about those little fish and secondly I started to think about what about other people with diseases and catching anything from the water ! so that is why I decided to google it. I have decided after reading all the different sides about this on this thread I certainly will not be going in to have my feet done now and will advise others against this. I really did love the idea and had always said I would have a go but do not feel happy about the whole franshise idea and people who are not qualified looking after the animals and the possible contamination, I feel they are just doing it because its the latest trend and money can be made. I just had not thought very deeply about it until I actually saw these fish and these questions had bothered me, So thank you for all the different points of view on this thread and I hope others take a step back and look into it further before jumpin in with both feet!
