An interesting moment when thousands of small fish are massaging tourists' feet at Nui Co Lake Tourist Area in Thai Nguyen, Vietnam on January 16.

The video shows a lot of small fish clinging to visitors' legs to eat dead skin cells.

The fish even covered the tourists' feet. That is a wonderful and enjoyable moment for visitors to experience for the first time.

The small fish will slowly poke your feet, making you both sad and numb, a feeling that no massage service can provide.

This fish resembles a professional pedicureist. You just need to drop your feet into the tank, these "doctor" fish will immediately eat the dead cells out of your legs, helping your feet clean and stimulating new cells to grow.
