The Fish Spa Experience This special breed of fish, known as Garra Rufa, is attracted to the vibration in the water given off by the pulse in your body. As soon as your feet enter the water, the Garra fish begin searching for the source of that vibration they feel. This is similar to the way a dog would sniff out a scent. This specific sub-breed does the exact same thing in the wild. So, our process is designed to mimic their natural environment, which keeps the fish happy and healthy! While they are busy looking for the source of the vibration from your pulse, their movement around your feet creates a very relaxing feeling that is often described as like bubbles all over your skin. The light sensation from the tiny fins rapidly moving across your skin is what creates this relaxing feeling!
