Fish pedicures, also known as ikan bilis treatment or toe-nail eating fish spa, are a form of exfoliation where tiny fish nibble away dead skin from feet. These unusual spas have gained popularity worldwide for their seemingly painless way of rejuvenating feet. In California, such services are permitted under strict regulatory conditions to ensure cleanliness and safety for humans and humane treatment of the small fish involved. Regulations and proper care must be adhered to for these unique spas to operate within the state's legal framework.
