A method of treatment of the skin of a human individual by fish which eat the top layer of skin includes providing a separate supply of fish for the individual, and suspending the skin to be treated in water in a fish container which may be adapted to receive a specific body part, such as a single foot or two feet, or a single hand or two hands. Each fish must be large enough to eat the top layer of skin of the individual, but should not have matured to the point of being capable of reproduction.
