Doctor fish

Doctor fish are a type of fish that live in warm water, usually in places like Turkey and parts of Asia. People sometimes go to spas that have a pool full of these fish and put their feet in the water. The doctor fish then nibble on the person's feet, eating off the dead skin cells. This might sound yucky, but the fish actually help to exfoliate your feet and make them feel softer. It's like a spa treatment for your feet, but instead of using lotions or scrubs, you use fish! Don't worry though, these fish have small, harmless teeth and won't make you bleed or hurt you. They also get fed well, so they aren't hungry and won't eat too much of your dead skin. Going to a doctor fish spa might be a fun adventure for some!
